I have a Tekno RC8T conversion on mines so I can afford to be creative with gearing since I run mech brakes and takes a good load off the motor.
Dan i am running the suggested 50t. Well im pretty sure its 50, i think stock is 54 for nitro and 50 is suggested. Someone correct me if i am wrong. Also as far as the pinions go, pick up novak ones off amain, they are $20 for 3 pinions. Best ive found for pinions. I dont think youll need 17 though, but i could be wrong, what is the length of the heats and main? If u run against gas and need long run time, smaller pin will = cooler temps and longer life.

Where is the Castle deal? Is it still going on? I stepped away from RC for a few months but I'm in need of a motor to finish a conversion. Thanks.

the 1512 and 1518 are only $65. i have a 1518 on its way to me for my rc8t. i was expecting to run higher pinions than on my mbx5t(2200kv 14-46) but here i read its lower pinions that keep the motor cool. cant wait to get the 8t rolling

anyone running the 1518 (long can "truggy" 1800kv) in a buggy? I bought that one for my rc8be, and ordered a 19t pinion to run 4s. What's the reasoning behind the two different motors? the weight savings between the two versions only seems to be a few ounces, but is that the reason?
should be more torque for the longer one.

A 1518 is going to be way too much torque in a buggy. That motor is designed for larger 15-20lb Monster Trucks like Savage XLs running 60+ Mph.

The 1515 sized can works fine in a buggy but is a little torque. I had good success with it running lower RPMS 25k or so and then gearing up. Very cool temps, but you have to be careful because brushless motors can run hot if there isn't enough load on them.

1512 is the right size for a buggy. even those have too much low end torque though.

Thanks, although I've already purchased the 1518 a month ago. I'll play with the gearing and make sure I find the sweet spot that doesn't allow the motor to get too hot. I can always dial down the power via the monster esc.

I run the longer 1800kv motor on 4s in my converted d8t, geared for 40mph, temps are around 65C, and plenty of power.
what temps is everyone getting from their lipos, in my ve8 they stay outdoor temp 28C but in the truggy the battery gets around 42C.
