Helko........Use only the recommended motors, 700 to 900ma lipos with micro servos, reciever, etc. in the TopGun planes. I promise you will not be dissapointed with the results. I have noted by the flight tests on Scotta's planes that they all tend to tip stall. I don't have any idea at this time what causes that problem. The TopGun planes do not display any signs of tip stalling. I have never seen an email that mentioned any flight problems at all. When stalled they just nose down and pick up airspeed. Instead of re-designing the TopGun plane, just build it as described on the CD.
