I dunno what your reasoning is that TT is crap but i got a TT .40 that will turn a 9x6 apc sport prop at 16500 with 200 on the pinch. It won me fast time 2 times in AMA 424 pylon racing. Everyone else running any other engine at comparable prices (<$100) have not come close. Bolt your Magnum one with a 9x6 APC on a Viper or Predator and see if you can beat me in Bowie, MD at a race. Has to be a .40 though.

For the price i think tundertiger engines are the best in there class. I have 4 of them. 3 .40 pro's and one .46 for my ultra stick 40. Everyone at my flying field keeps wanting to know what engine i have on my ultra stick too. While there engines are quiting on them, mine has never dead sticked me right out of the box.

I'm tired of hearing everyone bad mouth TT. Those people probably don't know how to set up an airplane right in the first place.
