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 ,,,
