Is this the .46NT engine?? I got one of these things. The limiters are defeatable on it as well. I was under the impression the the "trainer system" engines were like the OS LA series 'till I saw one a friend put in a GP Venus 40. Wow! That thing scoots! He also ditched the 3 blade prop and that flywheel mass thingie. The NT is supposed to be stronger from what I've heard. Let me know if I'm wrong on this.

I bought the 46NT for a relatively cheap combat spad engine, since it'll get buried and/or mid-aired a few times I didn't want to spring for another 46FX.

Thanks!
