i need to check out the cd-rom tail motor you mention. is it for dd or gears?
the mamba motor i have is 3200kv, 2200kv would be even more torqey (more kV = less torque more horsepower). most ppl seem to think 3600kv w/8t is reasonable with 3s 1200mAh. i hear 4100kv w/7t is also good, but the 7T 0.5M pinion is kind of hard to find and an 8T gives too much headspeed (~2500RPM). i figure i'd need a new brushless esc like the cc phx10 or similar to go with the mamba i have. if i decide to do it, i'll probably start with a 9T if i can find one in 0.5M.
I was thinking just the opposite on the motor. The motor in my Stampede is 2200kv. You're right, the mamba apparently would be a good motor if it fits. But then again I agree, you'd really be cooking with 8t. How many amp esc is in your car? Is 10 enough? I'd personally lean to 25.
As far as the cd motor, mine is 9 turns of 22ga. wire on a 20x5 mm stator. You can get some good ideas from gobrushless.com. I got most of my insight from a guy out in Washington named Art Newland. He put a similar motor on his Picollo tail and another homemade for the main and started talking about it in RCG. He is using total separates though, so I don't know if you're wanting to go that route. I bought a 2-in-1 to go brushless, but again, it's sitting in a box in the shop. If I burn out a tail motor (unlike Dennis, who goes through motors like Talon goes through blades) I'll likely use one of my cd motors there, but I'm pretty happy with the brushed on the main.
