The DS-16 Carbon represents Jeti’s new flagship, State-of-the-art, transmitter that sets a new standard for the RC Industry. Jeti’s final touches and finishes are outstanding. The front panel of the system is made of genuine Carbon Fiber with UV stabilized acrylic clear coating and the case made of anodized, CNC cut, solid aluminum.

This revolutionary, digital, 16 Channel, 2.4GHz, frequency hopping radio system is fully designed and manufactured by Jeti Model in the Czech republic. This is one of the most advanced radio systems on today’s market. With their solid CNC aluminum case with a fully integrated antenna, a mini USB port, built-in speaker, headset jack, metal transmitter gimbals with Hall sensors (4096 step resolution) and 9 ball bearings for precision movement, a large 320×240 backlight display and many other features the Jeti DC/DS-16s are sure to become the new standard in transmitter performance.

One of the attractive features of the Duplex 2.4GHz line of products is it’s full integration with all Duplex telemetry sensors. You can easily observe up to 40 different parameters in real-time directly on the transmitter. Or, by using the JetiBox Profi (sold separately) you can see your data in parallel mode giving you and your copilot valuable real-time information (see video).

One of the most important features of Jeti’s transmitters is the gimbal and switch function assignment flexibility. With the DC/DS-16 you are free to fully customize your radio. You can swap switches or sticks (Mode 1-4) and the on-board computer will recognize your changes and assign functions anywhere you like. Other important functions are programmable Sounds/Alarms and even user-recordable sounds. This audible alarm feature was specifically designed to keep you informed while also keeping distractions to a minimum. We think this is the best way enhance both your enjoyment and your model safety. You can simply set a receiver battery capacity alarm for the desired capacity used and once that number is reached the system acoustically and visually gives you warnings

We’ve all heard the expression, “I’d Rather Be Flying”  And after a long cold winter, I could not agree more! Without a doubt you and everyone else in the hobby has certainly noticed the trend toward almost-ready-to-fly (ARF) aircraft and more recently the availability of plug-and-play models at your local hobby shop.

87

This has widely been viewed as a positive movement in our hobby for getting more people flying quickly, while also providing many unique model choices for enthusiasts.  The pitfalls  however is that often development and manufacturing care doesn’t meet the user’s needs and expectations, resulting in only short term success.

In the sophisticated world of RC jets the plug and play options have been limited to small electric powered models.  Larger models being marketed as ARF’s primarily come as a painted bare airframe requiring the owner to provide all the onboard systems and layout.  Often also providing the builder with countless hours of head scratching, and in some cases reengineering and reinforcing, in an attempt to get his new model flying.

That is until now.

For more than 30 years, Bob Violett Models (BVM) jets has been a brand synonymous with providing well engineered designs, industry leading quality, and reliable customer service to the jet community.  BVM have recently taken their experience and thorough testing program to the ARF market by partnering with China based Premier Aircraft to develop and supply a new type of large scale jet. After significant BVM testing and a number of design refinements, BVM has released their first offering under this partnership, a 1/6th scale F-16, and is the basis for this article. Utilizing Premier’s manufacturing center to execute under BVM’s strict guidance and recommendations is proving to be a successful combination.

82

Acquiring a new BVM F-16 starts with the buyer, who can reach BVM direct at their Florida headquarters, or via any one of their many outstanding field reps around the world.  The F-16 is built to order and available in a number of standard schemes or in a custom scheme with details provided by the buyer.  Some additional delivery time may be necessary for custom schemes.  I elected the standard 3-tone military grey scheme with some custom markings on the vertical fin as seen in the accompanying photos.  Dealing directly with BVM couldn’t have made the ordering process and exchange of painting details any easier.  At the same time I also ordered the optional ordnance package, which includes a number of scale missiles and fuel tanks with their associated mounting pylons.

 

While my F-16 was being built I set about collecting the limited number of items I would require to complete my jet once it arrived.  After all, the beauty of this approach is that within a few evenings of receiving your new model you can be enjoying it in the air.  The owner needs to supply a radio receiver and batteries of their choice, as well as their own turbine and associate ancillaries (including UAT/CAT) to install and operate it.  I chose Futaba guidance and a Kingtech K140G turbine for power.  With ample power to fly this 30 lb. dry airframe and internal fuel valves, the K140 also would further reduce my assembly time.  The essential scale pilot is also an item sourced separately by the owner, and is available via BVM.  The scale cockpit is included with the kit and is secured between the fuselage and the canopy hatch.  For a more scale appearance I raised the back of the ejection seat one inch before installing the pilot.  Once he was secure I used some silicone to attach the cockpit to the bottom of the canopy hatch so it can be taken on and off as a single assembly.

During construction BVM provided reassuring status updates which avoided me having to overcome language, time and distance obstacles had I ordered factory direct.  From previous experience I can’t overstate the value BVM provides on this front.  During my wait I was also able to see a pair of examples of this new F-16 first hand from club mates who had ordered prior to me.  In both cases I was thoroughly impressed with the quality and obvious attention to detail that could clearly be of BVM influence.

1

A week before the successful maiden flight of my new F-16 (more about that later), two large cardboard boxes safely arrived via DHL Global.  One for the airframe and the other for the optional ordnance.  After inspecting the outside of the boxes I couldn’t resist opening them to reveal my new jet.  I was pleasantly surprised to not only find every component carefully wrapped and secured in its own bubble wrap packaging, but both boxes were lined on all sides by reinforcing sheets of thin plywood.

It took about 2hrs to completely remove all the parts and loosely assemble the complete airframe for the first time.  Most of that time was spent unwrapping the protective bubble wrap.  The attached photos demonstrate just how complete this airframe arrives out of the box, and two things were immediately evident.  First, it was clear that the factory had taken great care in the fit and finish and had assembled the model before crating it up.  In fact, the onboard air system still had air in it!  The second thing that impressed me is just how big and light this airframe felt.  Granted the turbine wasn’t on board, but despite its size I was easily able to maneuver the entire model by myself.  The finish is very well done with an accurate 3-tone grey scheme, well masked markings and a consistent matte finish.  I couldn’t resist adding the ordnance for some photos, and was pleased that all the predrilled pilot holes lined up perfectly with the supplied pylons.

The BVM supplied photo-illustrated manual made assembly very straightforward.  It walks you through removing items that are secured inside the airframe for shipping, as well as giving hints and assembly tips along the way.  One helpful suggestion was to order a pair of extra-long ball drivers, one 2.5mm the other 9/64th.  While the airframe appears to have a familiar mix of both metric and imperial bolting, the key mounting bolts for the fin, stabilizers, and wings are all a common head size.  Another nice feature of this assembly bolting is that the factory has installed a c-clip on the end of each bolt to prevent it accidently backing out in transit and becoming lost.

The model features all high voltage, metal geared, brushless servos, and high voltage digital air valves.  All the components in the airframe are installed and pre-wired so the owner just needs to fish all the air/fuel lines and servo/lighting wires through the fuse where they all accumulate under the forward cockpit hatch.  All the leads are clearly labeled thus simplifying what can often become a confusing task.

Let’s run through some of the main systems in the F-16, starting with the smoke/fuel system.  From the factory the airframe comes plumbed with dual fuel tanks over the CG, totaling 3.3L as well as dual forward smoke tanks, totaling 2.2L capacity.  Both systems use 6mm tubing and have their own dedicated vent connections with nicely machined magnetic plugs and reminder flags.  The smoke system comes plumbed with its own BVM electric pump as well as stainless steel injector stick.  For added fuel capacity I elected to remove the smoke pump and plumb my smoke tanks into the main fuel tanks with these empting first before the main saddle tanks.  This also gave me the opportunity to check all the secured connections within the tanks and nothing appeared to be rushed or forgotten by the factory.  Also, as you can see in the attached photos, inspection of the hidden glue joints revealed consistent and complete clean coverage along all joints.  The user needs to add his/her own fuel pump, filter, UAT/CAT and manual shut off valve all of which I did under the forward hatch for easy access.

The air system is controlled by individual one way electronic valves, with a dedicated valve each for gear up, gear down, doors open, doors closed, and brakes.  Synchronizing the actuation is all done via a pre-programmed electronic sequencer which worked flawlessly right out of the box.  The sequencer is also adjustable by the user if needed and I reduced the delay between the doors and gear slightly as a matter of personal preference.  The sequencer also digitally displays air system pressure in Bar and radio battery voltage.  The brakes use very little air and operate off the same air system for simplicity.  BVM shows in the manual how to properly lubricate the brakes to soften the non-proportional braking action and to date this has worked well without locking up.  Another nice feature of the air system sequencer is a built in failsafe.  Should you forget to add air or the system gain a leak and lose air the gear is automatically dropped and locked.  My limit is set for 3bar and in testing on the ground has worked repeatedly.  Another nice feature of the electronic valves is that without power they can be operated manually by pressing a small button on the top of each valve.  A BVM fill valve and pressure gauge reading in PSI also comes pre-installed in the forward equipment bay.

As mentioned previously, the F-16 comes with all high voltage servos.  Their connections are well labeled and come in a nicely shielded servo lead long enough to reach the radio compartment.  I’m using a Futaba HV RX and Powerbox iGyro to handle the radio signal to the model, and this is driven by a pair of 2-cell 1900mAh lipo rx batteries.

A very nice scale feature of the F-16 is that it comes will a full complement of navigation, anti-collision and landing lights all pre-installed, wired and programed.  The associated lighting controller allows the user to set a 3-position transmitter switch to control the lights by having the lights off, all on with the exception of the three landing lights, or a third position with all lights on.  Also the lighting controller in coordination with the retract channel automatically turns the landing lights off when the landing gear is retracted, and turns them back on when the gear is put back down.  Despite their intensity, even in direct sunlight, the lights use very little battery power and are run off the main RX batteries.  One of the only options I added was a simulated afterburner ring which I aquired from Details4Scale and it runs off it’s own controller and 6.6V LiFe battery.

Following the recommendations in the manual my model balanced perfectly on the recommended CG without having to move anything from my preferred locations.  No equipment is required in the nose cone and thus can be conveniently removed reducing the fuse length by 12 inches for storage and transport.  My layout can be seen in the accompanying photos and may provide some ideas for other owners.  The manual also shows a couple different layout configurations in the radio and turbine areas.  This forward compartment does get busy but provides convenient access to all the important systems.  I added a faux carbon tray in the center of the existing one to hide the visible plumbing, and also provide somewhere to mount my RX switch and onboard turbine data analyzer.  Care had to be taken to avoid equipment on this tray from interfering with the cockpit floor when installed.  One item that was included that I elected not to use was a molded turbine bypass.  The diameter of the K140 was slightly too large to fit within the supplied bypass, but I have seen smaller diameter turbines fit and perform well.

It took me less than a week of evenings to complete the equipment installation on my F-16 and get it ready to fly.  A very useful touch from BVM is the inclusion of full size templates with the manual for setting the control surface throws and neutral points.  These have turned out to be spot on.  I always like to do a turbine run test with all the installed equipment and plumbing in the airplane, with the exception of the turbine itself.  That gets mounted on a secure stand next to the model, pointed away for obvious reasons.  This allows safe adjustment of startup settings and once everything is operating smoothly, then the turbine can be mounted in the model.

After going over all the settings and doing the necessary range checks with the turbine off and with it running, everything was set for The F-16 to officially become an airplane and fly.   By following BVM’s setup recommendations the first flights went off without a hitch.  The F-16 only required a couple clicks of up elevator trim and it was grooving along very well, the Kingtech K-140 providing ample power.  The model slows nicely with the added drag of the doors open and gear down.  Despite using no flaps, the approach speed was predictable and landings were uneventful.  Ninety-five percent of my flying is from grass runways and to date the F-16 has exceeded my expectation for ease of handling and durability on grass.

Flying the F-16 using the high rate recommendations provides precise response and you quickly forget you’re flying a complex scale jet; rather it has the feel of a sport jet.  With the lights clearly visible in full sunlight and the K140 effortlessly pushing the F-16 through the sky, I couldn’t help but marvel that I was out flying and only a week had passed since I started unboxing the model.  I’ll be the first to admit that I was skeptical on just how well a sophisticated jet like a 1/6th scale F-16 could be supplied in a PNP format.  I’m very pleased to report that my skepticism was unfounded and the new BVM PNP F-16 as exceed all my expectations for looks, performance, and grass field reliability.  Perhaps this new offering from BVM may be your next hanger addition…but trust me it won’t keep you there long if you also “would rather be flying”!

Hatch Leash

A great way to ensure your canopy arrives attached to your plane, rather than flying off one way and the plane going the other, is to use two small pieces of wood from a matchstick or a wooden BBQ skewer. I epoxy one for the inside of the foam canopy and the other for the inside of the fuselage, then I wrap a small length of dental floss (which is strong and light) to each piece. I do this before pushing them into the foam while the epoxy is still wet. This system adds minimal weight to the plane, but ensures I don’t end up losing the canopy! My Multiplex Easy Cub is shown here.

The Perfect Building Guide

Here is the way to use your old credit cards and build straight at the same time. While building wing panels on plans, you have to ensure the ribs are 90 degrees to the building board. Old plastic credit cards are great building guides as their edges are perfectly square and the corners are rounded so they don’t get glued to the rib during construction. When they get ratty just throw them away, they don’t cost a thing ‘ that is, if you have a good credit score!

Custom Sanding Sticks

For neat and straight edges on parts I cut for my airplanes, I find it helpful to make custom-sized sanding sticks to fit into tight areas. Simply get some stick-on sandpaper (usually for electric sanders) and cut it into strips. Make your sanding stick to fit and then apply the sandpaper. The end result is clean edges for a professional-looking job.

Quick Connections

I’ve found that even when servo labels stay on, it is much too tedious to plug them all in properly. So, this is my solution. I bought several different colors of heat-shrink tubing: 3/8 inch for the female connectors and 1/4 inch for the male. To make it easy to determine the correct polarity, I draw dots on the tubing with a felt-tip marker to make connecting them a snap.

Making the most of your computer radio’s features can really improve your flying. Setting up a plane with the right radio programming will make performing all kinds of maneuvers much easier. Let’s see which programs will help improve our 3D flying. But before we address programming, let’s talk about using dual servos for the ailerons. Although most planes over .25 already use one servo in each wing, we just want to plug each servo into its own channel on the receiver. By not using a “Y” harness on the aileron servos, we can independently set each one to react differently to stick input, and that allows the plane to respond to inputs more precisely.

The advantages of having two separate aileron servos more than compensate for the weight added by the extra servo. By having a servo for each aileron plugged into its own channel, you can now use the spoileron and flaperon programs; these mixes will allow both servos to work in conjunction with the aileron stick. Both of these programs allow the ailerons to have dual functions. By setting them up on a 3-way switch, you can flip the switch in one direction and have both ailerons drop down and function as flaps while still working as ailerons. If you flip the switch the other way, the ailerons will move up and act as spoilerons while still functioning as ailerons. Flaperon and spoileron can both be used during high-alpha maneuvers to help stabilize the plane.

DUAL AILERONS

ABOVE LEFT: dual rates allow you to switch from one control deflection to another. On the Airtronics RD8000, the screen shown is where you program that in. When the dual-rate screen is in position 2, the aileron servo has 125-percent throw.

ABOVE RIGHT: exponential programming is used mainly to soften or decrease the stick sensitivity of the control around center stick. Expo helps pilots by allowing them to fly more smoothly and with larger control throws. On this screen, when the dual rates switch is in position 2 (high), the ailerons have 70-percent exponential.

On this screen, when the throttle stick is moved, it also affects the elevator’s movement. This helps the plane to maintain a straight downline.

Both of these mixes also allow aileron differential programming. This refers to the ratio of up to down movement of each aileron. Many planes need more movement from the upward-deflection aileron than from the downward deflection aileron. This allows the plane to roll true and eliminates unwanted yaw when the ailerons are applied. This is important because it will keep the plane flying true through all aerobatic maneuvers.

DUAL RATES
Dual rates allow you to reduce or increase control deflections by simply flipping a switch. This feature comes in handy when your plane is used for normal flying and hard 3D flipping around. You use standard or low rates (small deflections) to fly the plane smoothly, but right before it enters a big 3D maneuver, flip a switch, and now you have, movements of 45 degrees and larger on the control surfaces. Although you may need that much deflection for the maneuver, it would be difficult to fly the plane smoothly and with precision at normal speeds with those deflections. That’s where dual rates come in: after the maneuver is over, dual rates allow you to flip the rate switch back to standard rates and continue flying with lower deflections.

EXPONENTIAL

Radio mixing allows one transmitter control input to affect two or more flight functions. On this screen, when the rudder stick is moved, it also affects the elevator’s movement. This mix is used for knife-edge flight.

The spoileron or flaperon program allows you to have a servo for each aileron yet still allows them to function as one. The advantage is that you have control of the rates, endpoint adjustment, centering and the amount of differential for each servo; this lets you refine your plane’s flying characteristics. The Stylus’s Spoiron screen is shown.

Aileron-to-rudder mixing is useful if your model has a problem with adverse yaw when ailerons are deflected. You can adjust the percentage of mix to fine-tune the control response.

Mixing throttle to rudder also is useful when flying an upline at full throttle. Using a little rudder helps keep the model on track. The mix can be used to fine-tune the amount of right and engine downthrust you have to eliminate any veering offline that occurs at full power.

Another program that works hand in hand with dual rates is exponential. Exponential (expo) programming is used mainly to soften or decrease the control-stick sensitivity around center stick. Without exponential, a control-surface servo will move in an amount proportional to the amount of stick movement. For example, if you move the stick 50 percent of its available movement, the servo will also move 50 percent of its available travel. This is called “linear throw” or “linear movement.”

Using exponential changes the relationship between stick deflection and servo travel. With expo, you could move the stick 50 percent of its available movement and have the servo move only 20 percent of its available travel. The amount of servo travel depends on the amount of exponential programmed in. Keep in mind that exponential settings do not change the amount of servo travel available at 100 percent of control-stick deflection. If the stick is at the end of its deflection, the servo will be at the end of its available travel. Exponential changes the amount of servo travel that will occur with stick deflections of less than 100 percent. Servo travel is small at center stick, but as the stick moves closer to the end of its travel, servo travel speeds up to reach the end of its travel at the same time.

Expo reduces stick sensitivity at center stick and allows pilots to fly more smoothly with larger control throws. Imagine having large 45 percent throws on a control surface with a plane that you are flying straight and level. You move the stick 1/4 inch, and the control surface moves 1/4 inch; that causes the plane to veer off course quite a bit and makes your flight look jerky and erratic. With expo programmed in, that slight stick movement wouldn’t cause any surface deflection, and your flight would look smooth and controlled. Exponential is great when you have first flight jitters because if your hands shake expo prevents that anxiety from being transferred to the control surfaces.

This past weekend was the NEAT Fair (Northeast Electric Aircraft Technology Fair) and as usual, electric airplane lovers from all across the country made their annual trek to Downsville, NY to partake in this E-Power Extravaganza. The MAN Team was on hand and we captured some of the action that drew center-stage on the flightline.

One regular to the event is past MAN contributor, Dave Baron who had several E-planes at the event including his tried and true, giant scale B-17 Flying Fortress WW2 bomber. The 4-engine Boeing warbird has evolved over the years and now equipped with brushless motors, Lipo battery packs and Robart retractable landing gear, the B-17 is simply amazing to watch. Dave is real smooth on the sticks and puts on a great flight demo.

The model was originally built by Joe Beshar and today, the Flying Fortress is powered by Axi 2826-12 motors powered by 4S 3700 lipos, (one per motor) with Jeti Speed controllers on each motor. It previously had 4S/2P A123 packs in it. And originally it was powered with four AstroFlight 05 geared motors with 32 NiCD cells, (motors wired in series), and it eventually ended up with 36 cells before the Axi upgrade was done around 10 years ago! It weighted as much as 22 pounds. Weight this year is about 20lbs.
