RE: looking at several planes, what's the best one
I don't think he said he wanted a beginner plane. He did say he flys a ParkZone P-51 pretty well. If he can fly that well he should be able to fly a stable EDF. So actaully he is asking which of those are the most stable. If he can fly out the P-51 at full throttle he may be ready to step up.
