I cant wait to see what its like on 9s once i got the CD in!

The reason u keep going through tranny gears is because the stock gear that wears out is not hardened steel. You need to get the hd gear. It is hardened and will last as long as the truck. I've put about 30 runs through mine and the gear looks brand new still.

I've been running the 1520 in my LST XXL for a few weeks now on 6s. Geared for 45mph, I ran 2 packs through it yesterday back to back and at the end of the second battery, my motor temp was 117 degrees. Temp was 24 degrees (Celsius) up here in Canada. The truck can handle the power very nice, however my diff output cups are starting to notch out where the dogbones hit. I'm thinking about picking up some of Mike's Hardened diff cups (I think I saw some?).

I love this motor. It makes me smile. I couldn't imagine this motor in a Savage though, what a waste

Wow.... 117°... could you post your setup and some photos of your machine?

Yeah, I was baffled. I had a 2200 in there previously and knew that the lower KV geared would be more efficient/cooler, however I was afraid because I geared for a higher mph with the 1520... that the motor temps would be up in the high 150's (I understand that 175 is pretty much max?).

I will post setup/pics tomorrow. I'm just in the middle of cleaning the truck up from a good day yesterday :)
