Great stuff! Now I know some stuff to try, I mean look for out at the field! They don't seem to worried about cheating, it is just racing for fun. But I think there have been a few guys inside the motors! Limited to a stock MA 10x6 prop, any fuel, can only remove internal muffler baffles. Motors are supposed to be stock otherwise. I think these mods would not be breaking any rules, just "bending" them a little. I think I will buy a TT GP 42 next, since it really still seems to displace as a .40, and is an accepted motor with the club.
Oh forgot to add, I already have a Tettra tank
