hows that Sig 4 star 60 ...... the xtra easy 2 i have had the largest wingspan of any trainer available, at 69" it was great .... the 4* 60 has a 71" wingspan so i kind of would like that, even if it means getting a new engine, it would be worth it to have something a bit bigger and with more wing area .... i think ???!!!?? also, since i have the JR transmitter, what are my restrictions with regards to servos and receivers, brands, types, etc ... thanks... this stuff has been a bit of a mystery to me as of late ...... thanks again!!!
