I started with the LT-40 ARF, it has a 71" wingspan. The wing is one piece, so keep that in mind.

I have an OS FX 46 and it certainly is much more powerful than my friends Eagle II with an MDS 40.

Also, if it is not clear, radio compatibility has nothing to do with the plane, it has to do with the receiver and servos. UNLESS, those come preinstalled like an RTF.
