Very helpful reply. I have, however, already bought my Electrafun XP (much like the T-Hawk) 2 days ago. I launched it for the first time and it just turned right, I put full right rudder but it kept going right until the whole crashed and cartwheeled into the ground. I had to use some putty to balance the weight out so it would fly "more" straight. It did, and it flew well, except it took a long distance to complete turns. It then spiral dived and crashed straight into the ground nose first from 40m up. Now some wings ripped and the rudder servo is broken I think since the rudder won't respond []
