I bought a 36-50-3300 for my HPI NMT, but it has ended up in my E-maxx for the moment.

Performance is good in the maxx on a 5s2p A123,13/68 gears(3905 tranny). About mid 30's for top speed, wheelies up to about 10-15mph. With a novak HV heat sink it was running 120f after about an 8 min run. Without the heat sink I was hitting 170-180 in about 6-7 min. On a 15t pinion it was up in the 40mph range, lifting the front end into the 20mph range. I havent ran the 15t since I put the heat sink on but it was up close to 200f after a 9 min run.

I seized the front bearing after about a dozen runs, but for the price($35) I'm very pleased with the motor so far.

Gee, Medusa has a 36-50-4800. I have a 36-50-3300 Medusa on the way and an Eagle tree micro logger ready to go. I hope to have some good graphs of the Ammo Vs. the Medusa this weekend..
