Opfor:

Well I had two flights today with the A-10 and the TT.46. Awesome. Man she looks and fly's like the real thing. Not an acrobatic bird so some may be dissapointed. She is not twitchy at all, not that it won't turn sharp, it can but rather you don't get that jerky looking movement. It's more than just the way the throws are set up, it might be due to the weight. It fly's jet like.... hard to describe. Its fairly easy but I still had our ace land her she comes in fairly fast probably due to the weight She fly's inverted well and tracts through loops good.
If I recall the aft fuselage section is made from 3/16 balsa. That might be heavy ??? but if I had to build it again(and I would) I would cut a series of 1 1/2" holes in the sides and tail feathers to eliminate weight. Not too many though. With the motor hanging so far back literally every once counts a great deal more than a reg. plane that has it's motor closer to the cg. As far as a aux tank................ I tried that. If your set up works that way then go for it but again that extra weight of the fuel tank should be avoided. I would still use a perry pump as long as the motor runs RELIABLY. By the way The TT.46 runs with a 10-7 pusher prop at 13,300 rpm. Iam no pro by any means but will give any help I can.
