its not the fastest motor
but it is very reliable, and easy to tune
since its a big track your gonna need alot of top end, which the CV-R lacks a little
you may wana look at something like the fantom FR-12, due to the almazing top end which is great for big tracks, and the rebuilds are the cheapest i've ever seen
your other option would be a novarossi CX-12
for pull start motors anyways...
