For 70 dollars the T-15 is a very good egine.

I just bought an Rush Evo off Ebay and I was able to get it started no problem and to idle with hardly any tuning. They guy I bought it from was in Utah over 7000'above sea level. I am in Pennsylvania and maybe 1000' above sea level. The engine is supposed to have about 1 gallon through it but it has a lot of compression.

It's doesnt have great top end, but it does have good low end torq and is easy to tune.

The roto start is something you should look into. No more pullstarts. I also checked on my other truck, Duratrax Maximum MT and the roto start plate and gears will fit on that too.
