I have one of each now. I was wrong in my earlier post. I have the p1 in my st and the p2 in my gt8e. I don't know if I'd use it in 8th off-road but they are pretty quick and seem to be up to their rated specs.

I also found out that hobby King now sells them (rebranded) in a pretty cool red color. After bad experiences with trackstar I've been going name brand but I would actually buy the hobbyking rebranded ones since they seem to be the same just different color.

Either way they are pretty great and not too good to be true.
