We have had good experience in trying to match the free speed RPMs.

So...

CIM free speed RPM = 5,500
Drill rpm = 20,000

ratio difference = 20,000/5,500
If you do the math, you get about a 4:1 difference between the two (assuming that the Chip has the same characteristics as last year's). Amazingly enough, this is the same GR as the first stage of this year's DM GB (Zsun = 15, Zinternal = 45, Zplanet = 14).

We're planning on building a first stage for the drill motor, where the output shaft and mounting configuration will mimic the Chip. The GB after that will be identical (x4).
