I sorta agree with Britbrat. I have 2 TT engines, but they are the GP (bushed) type. Thet ran great out of the box and I have never had a moment's problem with either the 42 or the 61. The BB engines are supposed to be great, but I just wanted a low priced motor for my beginnings into R/C. If they last me 10 years that averages out to less than 10 bucks a year. But either the bushed or bearinged TT would be a good choice.
