I am kinda wondering the exact same thing. I crashed my trainer last fall and just completed my 4 * 40 kit. I installed the evo .46 NT that I had on my trainer. The plans only recommend up to .40. I think the evo .46 is the strongest .46 size 2 stroke engine there is. At least that is what it said in the AMA magazine. If I were buying an engine and didn't have this one already I would probably by a smaller one.


I am eager to hear the responses you get. I can tell you I taxied it in in the drive and I gave it full throttle for like one second and the tail was already in the air.
