fike dave vera is a factory driver for reedy
he's been in more a mains at a national level in twelth scale since the 80's than a lot of guys. he'll run the motor once or twice and will get a skimm of the topped and frsh brushes but remember its a national and i dont think but maybe a handfull of people can out finger him with the throttle and be more effeciant.
eventhough its second hand info straight from the horses mouth.
he was running a 10 double because its what mike gave him he didnt for see anyone racing 12 scale, the motor wasnt that efficiant
your running a 11 wind motor not the 8 and 9 wind motors these guys were running.
i run a lot of twelth scale here in florida and have tested with mods i have test a kr touring car motor and a trinity motor of the same wind but desiigned for 12 scale
the effeciancy is crappy compared to the trinity motor . a 12 scale motor is for twelve scale and ten scale is for tenth scale, .
