radio interference
 

If this has been addressed I'm sorry but I could not find anything on it . I just finished my 30 cc homelite conversion and put it in a hanger 9 cap 232.I ran it up and down the road to see how it handled and noticed while it was sitting still the rudder was jerking up and down and the motor also was fluctuating. what can I put in it to stop this as I sure it is not flyable this way.

You can find a lot of words about interference in the forum, try search.
You can also check this: never metallic pushrods between the trottle servo and the engine.
If you use pull-pull system the cables must not to be in contact each other. If the "interference" was only with the engine running check all the cables, switches and plugs. Warning with very long servo extensions. Good luck

I forgot to add that when the engine is not running everything works great.It is just when the engine is running that everything oes nuts.

I'm betting that you don't have a resistor plug. If you do, make sure that the ignition is as far apart from the radio components as possible. Another fellow had a similar problem, and it was because he cut off his ignition cut off wires on his magneto type ignition, and just tucked them away. If you have a mag type ignition, run a cut off switch with it. As mentioned above, make sure there is no metal to metal contact anywhere, such as in the throttle linkage, that can vibrate together. This can cause severe radio interference.

Good luck,

Thanks for the help.I'll try these things tomorrow and let you know if it worked

Thanks for the heads up AV8TOR that helped a lot .once in a while it still quivers but not near what it did . now I am going to reroute my servo lines as far from the motor and shut off as possible,and hopefully that will cure the problem.

Hi,

Glad that helped, but it's best not to fly it until the glitching is fixed/gone. If your antenna is inside the plane, try running it outside and attaching it to the top of the vertical stabilizer. I know it doesn't look as nice this way, but it's better than losing a plane!

Good luck,
