Theoritcal CC Motor Gearing Questions

None yet. Finishing up getting the 1717 in my flux. I'm waiting on a set of pinions for my truggy, then I'll put the 1800kv in it.

Well, I have news:
I installed a few days ago the 1518 (1500 Whats, 1800 KV) in my Truggy (RC8t). I am running my truggy 4S Lipos (Thunder power - 5200mah, 50C, Team Orion 5100mah, 40C).
This motor is a monster!
The 2200KV was geared to 14/50 (about 60 km/h), and the 1518 is geared to 18/50 (about 63 km/h).
The 1518 has noticeably more power than the 2200KV (which was installed earlier), it runs cooler (the motor reached 70C but it was after a very hard bashing session in deep sands. With the 2200, I had to stop every 7 minutes for cool down).
The run times were about the same (maybe a bit shorter with the 1518).
I am very happy with this upgrade :-)
