RE: SPECTRUM 2.4 DX7 Radio range?
Its not so much its range, it will fuction the same distance as any of thier other receivers.
Being a single reciever however its subject to shadowing from things in the airplane or heli that a dual reciever like the 6200 would have a good connection on one channel or the other at all times.
Use it on foamies and stuff you fly close in.
