I notice MJX doing weird things with their products. x200 has incompatible radio with all others(f45, x100, f47). WL radios are all compatible, even camera quad v959 can fly with all others (v911,v912,v929,v939,v949) expect you can't turn on the camera. If I didn't order 2 of f45 and didn't need camera on big heli I would move to WL v912 which is almost the same (a bit smaller) but no brushless and other upgrades available so far. All my other helis will be certainly WL
