Author Topic: Engine failure on take off (Read 308 times)

I had just lifted my r/c plane off the runway and was about 15 feet high when the engine started running very rough. I throttled back to see if it would at least provide some power. Then it quit. I leveled off, the plane started stalling, and then it impacted some heavy brush. The wings and engine popped off, but I was able to fix the damage in 15 minutes.

So whats the proper procedure for engine failure on takeoff?

If we're talking real planes, unless you've got 700' or more you glide and land as straight ahead as possible. Even if it means going into a lake. Try turning back lower than that and you run the serious risk of a stall/spin which usually equals no more pilot.

Leveling off was a bad idea. Push the nose down and get some flying speed. With an RC plane 15 feet is pretty high.

yeah, and fly straight. if you must adjust the bank, use the rudder. Don't hit the ailers.

Engine failure in an R/C plane - well there's only one procedure you should do: open your wallet and see how much money you have.

You did about all you could but you need to find out why the engine quit.

A mistake a lot of new R/C flyers make is they run their mixtures too rich. You want to lean it out until you get peak rpm and can throttle up/down the full throw of the carb without having the engine burp. During break in for new engines, I run mine rich at max power on a test stand (vice) with a little servo mounted on the workbench to keep the throttle full open. I just leave it until about a gallon of fuel has been run through then I bolt it onto the airplane. I run the engines lean because you can go from a low rpm to a high without running as much risk of flooding the glowplug. Also, while holding the airplane, a preflight runup should include a few seconds at max power in level, nose down and nose up attitudes with you holding the airplane in the attitudes. This will help you isolate where/why the engine is running rough.
