3D printing technology can create some amazing things, but how about a UAV that includes integrated electric ducted fans? Designed and built by a Boeing-assisted team at the University of Sheffield, this aircraft weighs 7.7 pounds and can fly at 45mph using its integrated motor. It is made up of modules that are bolted together, with the fuselage section (included the ducted fans) printed as a single ABS part. And the ducting inside can even move for greater pitch control! The motors and electronics are added later. We hear the team is working on a nearly 10-foot-span version that uses miniature turbines for power.3D_printed UAV1

Today, more than ever we are enjoying a literal “Golden Age” of RC electric flight. The amount of quality motors, batteries, controllers and connectors is just about limitless as are the types and sizes of airplanes you can fly with E-power. Even though there are plenty of plug n play packages out there where you get everything needed in one box, the newcomer can find it difficult get started. Whether you are a beginner or an experienced RC pilot, if you’ve never experienced an airplane with clean, quiet electric power, there are some basics you need to know to be successful. Let’s get started.

opener

Today, there are all types and sizes of electric powered models, take your pick.

The first thing that you need to understand with electric airplanes is you have to look at the entire power system as a whole. One that will work together for maximum power and efficiency for the plane you are flying. And with that, you have to understand how much power will be needed to fly your plane safely. Whether you’re flying a lightweight micro indoor flyer or a large 3D aerobatic plane, its performance is based on the amount of power it develops relative to its ready to fly weight. If you get an ARF model airplane, then everything will be included and you’re good to go, but if you are putting your plane together with separate airframe and power system components, then you have to know what will work together.

types

From trainers to sport planes, gliders and electric ducted fan jets, the choices are endless.

Power

Electric motors, propellers and battery packs along with a suitable electronic speed controller make up your power system. But you have to use the correct combinations of equipment for your system to operate properly. To determine the power of your model’s power system, you need to measure the voltage and current while the motor is running. The three important parts of the power formula are amps (A) , volts (V)  and watts (W). But before we can talk about selecting power systems, we need to understand some very basic things about electric power.

motor

Picking the proper electric motor and propeller is a very important first step.

A watt is the unit of electric power in the same way that horsepower is used to express power for an internal combustion engines. You produce a certain number of watts by moving electricity through a device that converts it to power. Movement of electricity through a power system is described by the term ampere (amp), and the force that causes it to move is the volt. The basic relationship between these units with the equation Watts = Volts x Amps (W=VxA.). The most important thing for modelers to understand is that you can produce watts by using a lot of volts and just a few amps or you can use a small amount of voltage and lots of amps. It all works together. What this means is you can use a small amount of battery voltage and a large propeller diameter/pitch size or a larger battery voltage and a smaller propeller depending on the requirements of your model. And to properly power our models we can use a simple rule called the “Watts per Pound Rule”.

Watts per Pound

This categorization is a loose, flexible way to estimate the amount of power needed for a specific size airplane while giving the performance required for safe flight. The rule is really just a guideline to determine how many Watts of power are needed per pound of airplane weight and is expressed as W/lb.

•             50W/lb. or less.  Very lightweight micro RC and slow flyers.

•             50 – 75W/lb. Sport powered sailplanes and gliders, basic trainers, lightweight scale planes, Vintage RC and RC Assist Free Flight designs.

•             75 – 100W/lb. – Basic sport flyers, intermediate aerobatics. scale low-wing designs and medium size warbirds.

•             100 – 150W/lb. – Advanced aerobatics, pattern flying, 3D planes, larger warbirds and EDF jets.

•             150 – 200 plus W/lb. Unlimited 3D aerobatics, warbirds and large jets.

–Fast Fact: 746 watts = 1 horsepower

Batteries and Charging

charger

Having a quality multi-type battery charger is an important part of the electric modeler’s workshop.

Compared to the NiMH and NiCad (nickel metal hydride and nickel-cadmium,) battery packs we used just a few years ago, the new generation of lithium Polymer (LiPo) battery packs (often referred to as Li-poly) have totally altered our definitions for power and flight duration. Where the older types of batteries offered 1.2 volts per cell, (1V under load), Lipo cells offer a nominal voltage 3.7V per cell and they provide much larger capacities along with an impressive weight saving. More voltage and more capacity and lighter wing loadings have really improved our airplane’s flight performance.

C-Ratings

LiPo batteries must be charged carefully and with chargers designed specifically for LiPo battery packs. Though there are many new Lithium battery packs on the market with extreme charge and discharge ratings, for the best longevity of your packs you should use a 1C charge rate. (1 times the capacity of the battery) Example: 3.3A for a 3300mAh battery capacity.

batteries

Lipo battery packs are the most common used today. It is important to pick the correct one for your model’s power system.

As with most things in RC, extremely high performance RC Lipo batteries with very large capacity ratings have become very popular. Some of these high performance packs have very high charge and discharge ratings up to 5 to 15C charge rates and 45C (continuous) and 90C (burst) discharge ratings.

Safety Warning: Because of their internal chemistry, extreme care is required when using and operating LiPo battery packs. Overcharging a LiPo battery can cause the pack to burst and vent violently and can cause the pack to catch fire. As for over discharging, most ESCs allow you to set a low voltage cutoff or use the default which varies by manufacturer. 3.0v is the absolute minimum anyone should use as allowing Lipo cells to go below this voltage will damage them. As with any high-energy electrical equipment and battery packs you should always carefully follow the manufacturer’s instructions for proper use.

Fast Facts: LiPo Packs

  • Unlike other types of batteries, lithium polymer batteries can be stored for one to two months without significantly losing charge.
  • Lithium batteries should not be trickle charged
  • Typical maximum and minimum voltage for Lipo cells should be 4.23V and 3.0V volts per cell respectively.

Connectors

connect

Like airplanes, battery connectors come in several styles and ratings.

Connectors are an important element in any electric power system, and you’ll find them in between motors and ESCs and between the ESC and the battery pack. The most important thing to remember is to use the proper size connector for the battery and power system being used. Most of the battery manufacturers today include connectors already attached to the power leads or at least include them in an accessory bag. Using a low quality connector or one that’s too small increases resistance in the wiring and this translates to heat and lose of power. As a rule, you should use as few connectors as you can to maximize efficiency. Many experienced modelers will eliminate the connectors between the motor and ESC by soldering the power leads directly together.

adaptors

Adaptor cables help you manage your battery cha

Most brand name electric equipment has its own brand and type of connector and you need to use the matching type to charge your battery packs. You can however, simplify your life by switching all of your battery and ESC connectors to a generic one. This will then allow you to mix and match battery packs between airplanes and you can use the same charger to service your battery packs. If, the charger has the proper settings to match your packs. The most common at Deans Ultra T-configured connectors and Anderson Powerpole (APP) (also referred to as Sermos connectors). The Deans require soldering and some heat shrink tubing, while the APP connectors can be soldered or crimped onto the power leads with a special crimping tool.

lineup

At the annual NEAT Fair in Downsville, NY, the electric power airplane hobby is highlighted for all to see.

Glossary:

Ampere (Amp): The standard unit of electric current. The current produced by a pressure of one volt in a circuit having a resistance of one ohm.

Battery Eliminator Circuit (BEC): – A circuitry that allows the battery that runs the motor to also power the receiver and the servos. This is often built into the ESC

Brushed Motor: The traditional type of electric motor where brushes make contact between the rotor and the stator. The touching of the brushes essentially creates the timing and current to make the motor spin correctly.

Brushless Motor: Type of electric motor used in RC electric aircraft. Brushless motors are much more powerful than traditional brushed motors, and are commonly used in electric aerobatic aircraft. They can be inrunner or outrunner motors.

Current: The flow rate of electrical energy. Measured in Amps

Capacity:  Is a measure of how long you can draw a specified current from a battery. It is measure in Amp Hours (Ah), or more commonly for the scale of equipment used for electric flight, mill-Amp Hours (mAh).

Electronic Speed Controller (ESC):  The thing that controls how much current is given to the motor and hence how fast the motor runs. Often they have a BEC (see above) built in.  There are two main types – brushless and brushed.

Horsepower (HP): A measure of the rate of work. 33,000 pounds lifted one foot in one minute, or 550 pounds lifted one foot in one second. Exactly 746 watts of electrical power equals one horsepower.

Inrunners: Get their name from the fact that their rotational core is contained within the motor’s can, much like a standard ferrite motor. They run inside the can.

KV:  A rating for brushless motor that equals a 1000 RPM per volt.  So a 5KV motor would spin at 55,500rpm approximately if you applied 11.1 volts (3s).

Li-Po: Stands for lithium-ion polymer battery. These are the most modern kind of battery pack being used in electric aircraft. They provide enormous amounts of power for their size, especially when used in conjunction with a brushless motor.

 mAh (Milliamp Hour): A measure of a battery’s total capacity. The higher the number, the more charge a battery can hold and usually, the longer a battery will last under a certain load.

NiCD:  Abbreviation for nickel cadmium. They are a form of rechargeable battery cells used in radio control gear as well as motor battery packs. NiCDs are being used less and less these days, as NiMH and Li-Po batteries take over.

NiMH: Abbreviation for nickel metal hydride batteries, they are the successors to NiCDs with much better performance and up to 3 times the capacity for an equally sized battery. Only Li-Pos top NiMHs.

Outrunner: The other type of brushless motor, where the outer shell, or ‘can’, of the motor rotates with the shaft. The extra inertia produces more torque, so outrunners are more powerful than inrunners and rarely are geared.

Power:   For electric models this is a product of voltage and amps and is measured in watts.

RPM (Revolutions Per Minute): The number of times an object completely rotates (360 degrees) in one minute

Voltage: A unit of electromotive force that, when applied to conductors, will produce current in the conductors. Voltage is also referred to as electrical pressure.

Watt: The amount of power required to maintain a current of 1 ampere at a pressure of one volt when the two are in phase with each other. One horsepower is equal to 746 watts. Watts are the product of volts and amps.

meter

A power meter is a handy piece of equipment to have to check how your airplane power system is operating.

Now that the ArrowMaster has been completely built and final sanded, the really fun part begins–covering the plane and making it look truly unique. For this project, I used UltraCote as it’s very easy to work with and produces outstanding results. To do this job, you need a covering iron, a straight edged ruler (36 inches,) a razor knife and lots of new blades. Also a tack cloth works very well for removing any left over surface dust from the model. It is best to first work out your covering scheme from photos of a real airplane for a guide or by drawing sketches of what you want. Let’s get started

OLYMPUS DIGITAL CAMERA

To get warmed up, I started with the vertical fin and rudder. To add to the classic look of the ArrowMaster, I decided that I wanted some checkerboard on the rudder, bottom of the wing and the bottom of the stab. For the rudder, I used 1″ square checks. This is the first time I’ve worked with checks and I thought that working with it would be difficult, in fact it was easier than I thought and the results speak for themselves.

OLYMPUS DIGITAL CAMERA

The top of the stab is solid white and is covered after the bottom is completed.

OLYMPUS DIGITAL CAMERA

Here’s the bottom of the stab covered with the 1″ check pattern. Notice that where the tail feathers are glued to the fuselage, I left those uncovered.

OLYMPUS DIGITAL CAMERA

One thing that I like to do is to cover all cutout areas like where the ailerons are hinged at the T/E of wing. When I cover the wing surfaces, this allows me to iron the covering to the lip of the covering that I’ve wrapped around the edges. By doing this, the main covering becomes firmly attached to itself and will never come loose or shrink away from the edges. Another bonus is that the seams are almost invisible.

OLYMPUS DIGITAL CAMERA

cov05 – For the bottom of the bottom wing, I used 2″ checks. I started by centering the pattern on the wing bolt plate. This is important as it determines the pattern for the entire wing.

OLYMPUS DIGITAL CAMERA

Here’s onewing panel completed. The aileron and servo hatch are covered with separate pieces to continue the checker pattern.

OLYMPUS DIGITAL CAMERA

It was easy to keep the checker pattern matched to the wing bolt plate.

OLYMPUS DIGITAL CAMERA

Like the aileron cutouts, I covered the center section cutout separately.

OLYMPUS DIGITAL CAMERA

To keep from wasting material, I left the L/E bare and covered it with solid red.

OLYMPUS DIGITAL CAMERA

I really like the way the red and white look when the covering is shrunk nice and tight.

OLYMPUS DIGITAL CAMERA

The bottom of the top wing is ready for the red L/E.

OLYMPUS DIGITAL CAMERA

The top of the top wing is also ready for the red trim. Note the pattern in the center section of the wing.

OLYMPUS DIGITAL CAMERA

The red L/E has been applied to the bottom first and then the to the top of the wing.

OLYMPUS DIGITAL CAMERA

Here I’ve added the trim to the center section of the top wing. Looks really sharp!

OLYMPUS DIGITAL CAMERA

I covered the edges of the engine compartment in the same manner as the bottom wing. The interior of the compartment will be painted after the covering is completed. The rest of the fuselage covering went on without a hitch.

The new Revolution Design Racing Products Ultra Flat Head Carburetor Wrench is a dedicated flat head screwdriver to adjust and monitor the carb needle settings on nitro and gasoline engines. Offering a hardened spring steel 4×0.8mm tool tip the wrench is ideal to adjust the carburetor’s mixture needles while a gauge incorporated in the tool blade helps to monitor the adjustments made. Simply hold the gauge in place with the fingertips and rotate the screw driver into the desired direction to richen or lean out the carb setting – the red anodized indicator will clearly display the changes made. Part of the tool handle is also a rubber plug that helps to securely stop the engine by pressing the wrench against the flywheel. As usual the tool is constructed from high quality 7075-T6 aluminum while the blade is made from high quality spring steel. Laser-etched logos round out that signature Revolution Design look.
