RE: thinking of mojo
I have the 60 mojo with Saito 100 turning a 16x4w on 30% nitro. That is a PERFECT combo!!!!! Trust me and others, that combo will teach you everything that you would ever want to know in terms of 3D-most believe that it is the ultimate in 3D training. The plane is extremely tough, slow, stable when you want it to be, smooth and just locks in manuevers. I have worn the covering on mine out on the top of the rudder where I have drug the tail on the ground in inverted harriers so much. I can do really tight inverted harrier 8's within 6" of the ground with trememdous ease. For servos, I am using futaba 3010's everywhere with robart hinges and a 6volt batt for added speed and strength.
Try the 60, you will love it.
I also have the mojo 40 and burrito and they fly awesome too just a bit faster in their maneuvers and not quite as "solid" as the bigger 60.
Good luck!
