CRT.5 motor mount problem - RC-Monster Forums

Lol didnt even think about that... I'm running a Feigao 9L with a Mod1 Mamba Max and (at the moment) 3s 4000mah 20C packs I made myself... looks like they will be a little big to put right on the chassis, so I'll either make up a mount to let them hang slightly off a bit, or get some smaller packs... or get a bigger chassis lol (running stock pro chassis at the moment).

Will the CD affect the braking at all if I go esc braking...? cant imagine it would...

Come to think of it I don't think a brake servo will fit, so motor braking it is! dont think the L will get too hot :P

You will not have any issues with motor braking. Just up the center diff fluid weight, if your rear tires unload too much on hard braking.

The mm should not have any issues with the 9l, I run the same combo in a very heavy tube frame buggy, and it is geared for 45mph. No heat issue, just traction (a lack of it!).

Make sure you have some airflow over the esc and motor and have a look at the heatsink of the mm. Some are not help on the the fets properly, I pulled one off and re-attached it with thermal epoxy on each fet (just a little). Should help with hot spots.

My CRT.5 is running pretty much that same EXACT setup, except with a regular MM, and a CCBEC. It's geared with an 18t pinion, and the extended chassis I made for it is the same length as the RCM chassis. The 9L is a couple years old, and does just fine. The hottest I've ever gotten it is maybe 150 deg. The MM gets to about that temperature as well (no fan). Mine runs all truck tires (HPI Yokohoma Geolandars for the street, Holeshots for the track).
