ditto unstable

today i just put the back plate on my Hyper .21 to get rid of the pull start for a few reasons.
one like you said less moving parts = higher speeds.
two pull starts break over time.
three my arms get tired of yanking on that cord on those days when it wont fire up.

the back plate was $10 and i ordered the starter box, which will be like $100(give or take) and will work with my 1/8th buggy and 1/10th on-road.
