I need advice from a professional who has built and flown nito powered scale helicopters. My creditials are that I have built and flown RC helicopter ranging from 30 to 90 size airframes all of the pod and boom design. Now I want to get into scale. The model I desire to emulate is a MD500E. I have choosen to mount a fuselage of this design on the mechanics of an Align 600N LE. I have encounted very little information on this airframe but what I have read is that vibration is a serious issue that seems to manifest once a scale body is is attached to an existing airframe. Before I take the pluge into this realm of RC helicopters what are the things I must be aware of and how to negate the possibility of failure.
