Gearboxes for shooter?

[gorrilla]

oh-kay....

so we've been prototyping a shooter mechanism, using a CIM and the kit wheels from last year...only problem, we dont have any (easy) ways of powering it, toughboxes only give us around 300 RPM, so we took out a few gears and got it down to 4:1 wich should give us around 1200 RPM(hopefully)

now ive heard(read) about other people just directly driving the wheel off the cim motor how can this be done?


1200 RPM should be enough right? if not we can use chain reduction(upduction)


so the question is....what other ways are there to do this?


(yes i read the other thread, this is more from a assembely standpoint though)
