No, don't buy a new TT.46, go get a magnum,os or better yet, a supertigre 51. I have a TT42, not the same animal, but it took a while to get it right, it seems that the TT's have no mercy for lean runs, mine was almost cooked and lost due to my low tank position in the pulse xt.
Whoa, I strongly disagree with this statement. While I like ST's also, the TTPRo 46, with a bit of castor, is very resilient. The first engine I really had to tune was a used beater TTPRO46 and I botched it up time and time again. It was so lean at times, it would deadstick, then too rich, blubbering all the way around the field. This was before Idiscovered RCUand RCG, now I know what I am doing, but that beater 46 still flies great.
