As the person who originated the Triangle Series and did the rules throughout the 12 years, I dont understand why someone needs to re-invent the wheel with another set of rules for the same plane. Oh well.

My honest opinion as I have built a hundred of them and tried everything to make sure cheating was impossible, that the 10 x 6 prop APC is going to be the best. The T-34 is very draggy and the lower pitch will be helpful. Irun the 10 X 5 which was always fast out of the turns. The 9.5 X 6 was also very popular. I also run a 2-3/4" spinner which is just slightly oversized which is 70mm. Throw the tank away and use a good tank such as sullivan, tetra or dubro.As to the hardware, I toss the wire and use 2-56 and 4-40. As to setting the plane up, Ialways set mine up tail heavy as they turn better.

Out of the engine choices, stick to the O.S. Tower's run hard, but they dont last to long. If you dont run the O.S., the Thundertiger Pro would be the next choice. To buy the supertiger and there is a clause they may make it illegal is just a waste of money. First person to win with one will make the engine illegal.
