hello fellows ,,,

several years ago i tried a u.s. engines 41cc ,,, got so much RF noise from it my plane could not fly ,, i made sure there was no metal to metal ,, moved the battery ,, and it was a fm radio ,, tried a lot of things but could not get rid of the noise ,, so this turned me off to gasser's ,, but now i would like to give it another try ,,
can someone please tell me ,, the gasses with no flywheel ( the electronic ignition kind ) do they eliminate RF noise ?? ,, if you had an electronic ignition gasser would you be concerned with RF noise causing a crash ???
i would be gratful for any answers or comments ,,
thanks fellows ,,,

Even with electronic ignition RF still applies and can be a problem. Resistor plugs, shielded plug wires and all have made it better but you still need all of what you already know which is no metal to metal from the engine, no lose metal connections like clevises with lock nuts, muffler bolts, etc. On metal pull-pull cables you put a tube of one of the cables to keep them from rubbing together, personally I use Kevlar 100lb cord on my 50cc planes, way lighter and no way it's gonna create RF

There are probably hundreds of posts on RCU from people that had RF issues using a gas engine. If you were to read through most of them to the end the problem was usually traced back to poor assembly practices and work out radio/electrical components that had nothing at all to do with the engine.

I believe that all of the current production gas engine ignitions made for R/C are about as reliable and noise free as can be had. The rest is up to the purchaser to use quality products and good assembly techniques.

thanks for answers and comments fellows ,,
you would thing in todays electronic age someone could invent a small device you plug your reciever into that would eliminate rf noise ,, thanks for the replies ,,,
