Multi-Servo Control Surface Setup Made Easy

Multi-Servo Control Surface Setup Made Easy

With many of today’s giant scale aerobatic aircraft multiple servos are often used to move each flight control surface. Modern computer radios actually have specialized menus to help setup and adjust multi-servo installations, but you can do it the old fashion way as well by using programmable mixes. Basically you setup a two servo setup (for ailerons […]
Exterior Details: Dummy Control Linkages

Exterior Details: Dummy Control Linkages

There’s an old saying that says “scale models are really never finished, you just stop adding details to them”! Each modeler has to decide for himself when enough is enough. For me, I enjoy adding medium easy to see details to the top surfaces of the wings and control surfaces and in particular I add dummy […]

Magnetic Cowl Attachment

Magnetic Cowl Attachment

Neodymium magnets are members of the rare earth family and made from a combination of iron, boron and of course, neodymium. They were developed by General Motors and Sumitomo Special Metals in the early 1980s and are the strongest permanent magnets to date.  These magnets are truly amazing. Their strength is over ten times the […]
How To Repair a Fiberglass Engine Cowl

How To Repair a Fiberglass Engine Cowl

The great thing about almost ready to fly airplanes is that for the most part, they come with great looking fiberglass engine cowls that fit beautifully and often are painted at the factory. The general method of attachment to the fuselage is the use of through-the-cowl screws making assembly quick and simple. After time however, […]

Get into Gas: Expert Installation & Setup Tips

Get into Gas: Expert Installation & Setup Tips

There are lots of good reasons to use gasoline engines to power your model airplanes. Generally speaking, they are easy to start, and run very reliably while producing their peak power at lower rpm than glow engines of similar displacement. With lower rpms they tend to make less noise and burn less fuel per minute […]
Troubleshoot Gas Engines — 11 Tips for Reliable Performance

Troubleshoot Gas Engines — 11 Tips for Reliable Performance

OK, so you’ve installed your gasoline engine properly, and made sure that the fuel tank is properly installed and the fuel lines and fuel filter are all hooked up correctly, but you still can’t get any fire in the hole—the engine just won’t start. As a safety note here, we always recommend using a properly sized heavy […]
Micro Warbird Makeover

Micro Warbird Makeover

Over the past several years, the arrival of ARFs has provided a means for many to quickly get into RC flying. Today, preassembled models have improved to the point where many exceed the level of ability, interest, and even flying skills of the purchaser. No matter the reason, ARFs do fill a very necessary niche […]
Aileron Differential: Why it’s so important and how to set it up

Aileron Differential: Why it’s so important and how to set it up

For years, depending on the model setup, modelers often used offset servo output arms and bellcranks to achieve differential aileron movement. Today, however, using separate aileron servos and the aileron differential program menu in your computer radio has greatly simplified the task. But before we take a closer look, let’s first check out the mechanics […]
Build a Scale Radial Engine

Build a Scale Radial Engine

Adding a dummy radial engine to your plane is an excellent way to add that scale finishing touch. If you have been a scale modeler for just about any amount of time, you have probably know about Williams Brothers (WB) cylinders and may have even used then from time to time. WB scale accessories are […]
Fly a Negative Snap from an Inverted Climb

Fly a Negative Snap from an Inverted Climb

There is no doubt that many aerobatic enthusiasts are interested in performing extreme moves. It is important however, to build your aerobatic sequences on a solid foundation. Years ago, when I first became interested in aerobatics, 3D flying did not exist. Instead, we concentrated on precision aerobatics and honed our skills while competing at various […]
How to: Get the Stars-and-Bars right

How to: Get the Stars-and-Bars right

If you are one of many modelers who acquired an ARF-type model of an American airplane, the chance that its star-and-bar markings is correct is about one in 10. It’s sad but true. Among models built by usually careful modelers and displayed at meets, like the Toledo Show and Joe Nall, the situation is somewhat […]
How to: Make a Cooling Baffle for a Radial Engine

How to: Make a Cooling Baffle for a Radial Engine

Warbirds with powerful engines usually develop high operating temps unless they are carefully integrated into the airframe. Therefore, they really need a custom designed cooling baffle to keep temps down. Those that think the big round hole in the cowl is going to cool that engine, as is, are usually in for a surprise after […]
