Best engine there is for that money, nothing, and I mean nothing comes close !
Don't get me wrong, there are faster engines around... but not below 300 dollar.
Great engine, you won't regred... or it must be that you didn't looked at a 4 stroke... but that's a whole other story
ps. The HPI .18 stock engine is also not bad if you don't want to go to a startbox. But it doesn't compare to the TZ ! And no
the TZ is not available with a pullstart..
