Getting to Know Your Engine

Getting to Know Your Engine

Before you can effectively use your engine without destroying it, it’s important to know it key features, their purpose and how to adjust them. Needle Valves are tapered rods that are used to adjust the fuel mixture by restricting the fuel entering the carburetor. They come in a variety of sizes and shapes, and are […]

Eagle Tree’s new Guardian 2D/3D Stabilizer

Eagle Tree’s new Guardian 2D/3D Stabilizer

This is Eagle Tree’s new Guardian 2D/3D Stabilizer in my SU-26 airplane. You can see how small it is compared to a quarter, so it will fit just about anywhere in your model – no matter how small the plane. It should be mounted in a level orientation (it can even be mounted upside down), […]
More Vibration Cures from Tony

More Vibration Cures from Tony

On this continuing issue of trying to cure vibrations, Tony had some issues early on in his nitro scalers with vibration, and an important point to remember is that it’s a scale helicopter.  That means working with the pitch and throttle curves so it sounds like one and flies like one.  Most electric helicopter require a […]

Isolating the Source of Vibration

Isolating the Source of Vibration

Jim – Here are a few things I would suggest to isolate the source of vibration. Keep going down the list and you should find the problem. 1. Remove the main rotor blades and start the engine. Since this is an experiment, take the helicopter well away from the pit area and run up the […]
Solving the Vibration Puzzle

Solving the Vibration Puzzle

Hello Paul, I hope you might be able to offer some sage advice on a project that has me stumped.  I just completed a Century Heli / Funkey MD-500D body as an OH-6 "Loach".  For mechanics I'm using my flybarless Chaos 600 with MicroBeast that I've been flying over a year and a half. I […]
Servos for 3D and Extreme Maneuvering

Servos for 3D and Extreme Maneuvering

For those of you flying extreme 3D maneuvers, servos are now being offered with metal gears. Made from a mixture of aluminum, steel and brass, these gears are 16 times stronger than the standard gears. However, they do have one big disadvantage, and that is they will wear over time. Depending on how hard you […]

Model Avionics RevGlow and TJ RevMax

The RevGlow is finally a lightweight switchless way of igniting your glow plug. The RevGlow powers the plug for 12 seconds as soon as rotation is detected by the ThrottleMax sensor, but will not power the plug if the throttle is above 25%.  Now you can have an added measure of safety to keep your […]
Servos: Is a high price tag worth it?

Servos: Is a high price tag worth it?

Since I’m certainly no expert on modern digital servos, I called Hitec RCD and talked to their servo expert – Mike Mayberry – to get the technical information for the rest of this article. And the first thing I asked Mike was what are we getting in these higher performance, and higher cost, servos? He […]
Getting to Know Your Servos

Getting to Know Your Servos

Many years ago new radios came with four servos. These were not standard servos, or high speed servos, or high torque servos, but just plain ole servos. That’s all there were, and we were very happy to have them. Early radio manufacturers also used a specific color so their radios could be easily identified from […]
Training With A Flight Simulator – 2

Training With A Flight Simulator – 2

Flying a radio controlled airplane or helicopter is much like riding a bike. Someone can tell you all about riding a bike until they are blue in the face, but it does no good at all until you get on a bike and get a feel for the balance and control for yourself. And flying […]
