Gee, really? I figured since this was the Savage forum that you were converting a Revo.

j/k

Maybe he's asking what kind of Savage? Savage 21/25, X, X SS, or XL?

Thats why I didn't include it in the initial post. But I am converting a Savage 25. The diffs are already upgraded with hardened gears aluminum diff cups and bulks.

2 or 3 speed?

And what size (diameter) tire will you run?

2 or 3 speed I have the option, and current tires are 40 series pro line mashers 6.6" in dia. Also have pro line 40 series mulchers that are 6.1" dia.

Stick with the 1521, I did the 1527 on 6S and it wasn't controllable at anything over half throttle. In fact it wasn't even that fun to drive. I have a 1521 in my Savage now and that is much better. I use the 1577kv with 6S Flightpowers and a gearing of 52/16. Good mix of wheelies and top speed and temps stay reasonable. Get the new high speed 3rd gear set that just came out and top speed is even better! The only drawbacks are you still get a lot of busted drivetrain parts! Guess that goes with the brushless territory.

The 1521 1y sounds good. I would stick with the smooth can for battery clearance with the flm chassis. Gearing with the 52t spur and an 18t pinion wiil get you around 45mph and also help with battery clearance. I figured that gearing with the 2 speed, if you use the 3 speed you should pick up 3-4mph.

Only issue with the flm chassis is that if you try to run a small pinion or spur, the motor will intrude on the battery space. Just something to think about. Otherwise you project sounds like a beast! The 1521 should put out some power. I plan to run mine on a 1515 sized 1200kv aveox and 8s lipo. Have to use an air esc though, but not too bad.

Which 1527 did you have? Did it run cool through the pack? Looks like the 1521/1y/s is the right direction. I want insane power, I'm building this more as a exhibition truck.

The idea I have in my head is. Half throttle down the road, punch it and wheelie past my buddies with nitro savages, and buggies. This is not going to be raced as I have 16 other r/c's I do that with.
