Rummy's Savage E-5SC

I think the 1520 is more than enough to push that truck around. A 1717 would get less run time, wear out the truck faster due to excessive torque, heat up the batts quicker due to larger current draw, etc. Other than looking cool, it's a loose loose with the bigger motor. Just my opinion.

You have no idea what you are talking about.

A 1717 would be the logical choice as it produces more torque. It has a larger diameter stator so it will be able to procue the needed torque.

I have run both the 1520 and the 1717 and the 1717 is the clear choice winner for a heavier vehicle, and a longer wheelbase vehicle.

I ran both with a MMM and a zippy 5kmah 40c lipo. No heat issues on the esc or lipo with either but you could feel the torque difference with the 1717 and it ran cooler...

Nothing against the 1520 but it is a good 1/8 mt motor. Get much bigger and you need a larger motor. I would like to see a 1725 motor, around 1400kv for 8s use with the MMmxl.

But this is just my opinion too, sure I may have days of runtime with hundreds of brushless setups but what do I know...

Interesting. Well, I have never run a 1717, so as linc suggested, I can't speak from experience on that motor, only based on everything I've read on other related forum posts, which is as I stated earlier, it is an amp hog. I do run a 1520, and can confirm that it is a torque monster, quite efficient, And total overkill for my standard length Savage - wouldn't have it any other way. Best of luck on your project, hope it goes well . . . Looking great so far!
