RE: advise on a new elec heli
you can get the fixed pitch heli from LMH OR some times known as LITE HELICOPTERS .they have glow types to electric and have a few models to choose from.. you can use any 4 ch rx and transmitter/sender with them but i dont think you could use standard size servos so you need slightly smaller servos .
they fly ok with fix pitch but i would recomend a colective pitch any day over fixed pitch.
