Love those wheels ding
.
I have a TMS Challenger 17x2 that goes well in the "Cobrat",also have
a 19 turn Komodo Dragon that is a good motor too on a 21 tooth pinion
and a 7.4v LiPo.
I don't remember 'em back in the day(I always ran Parma's in my Optima Mid),
but TMS's don't seem to be bad motors at all.
