Yeah, I have a couple of 911's, a 912 and a 913 as well...
911 is great indoors, 912 great outdoors (in mild wind) and the 913 was a rash purchase and I haven't flown it. By all accounts it's not as good as the 912 anyway.
A 9x will bind to all the previously mentioned WLToys range (but
not 3d capable 922 heli or any of the 2xx range quads) with the right module (the FrSky I believe)
Of all the bunch, the 939 is the best. New gen 949's are actually 929's with different canopy's and the 959 is an old gen 949 with firmware added for the camera. All fly well outside and are quite capable in mild wind, but turbulence is massive and off putting.
For the price, any of the range is superb. The only thing that comes close in value for money terms is the Husban X4 - it's a better machine but substantially more expensive (I have one of these as well...)
Latest toy has landed...
Build well underway
