Just picked up a motor for the flm savvy - 02.18.2009, 11:41 AM

Anyone who is familiar with the flm tranny forward savvy knows that motor choices are a bit limited due to the proximity of the motor to the batts. I was originally looking for a 1521 1y smooth can, then went to a medusa 80mm 1600kv. Both were to be run on 6s lipo and a MMM. I plan to get the flux single speed parts for the tranny, so that I can ditch the mech brakes and servo.

Well, I ended up finding a deal on a 1521 2y (780kv) for 80 bucks shipped! So I have decided to use that on 10s lipo with the lutach 10s esc I have. Looking at the speed calc I am guessing the flux tranny ratio is similar to the 2nd gear of the 2 speed. With 7" tall moab 40 series tires, 16-18/47 gearing should put me where I want to be. Not sure how the motor wil perform running around 30k rpm, but we shall see. All I lack to finish this is the flux tranny parts... Hopefully they wil be available soon!
