1. Way simpler
2. Much stronger braking
3. No fade problems
Maybe others will have different opinions but I really can't see any reason to mess with mechanical brakes on these cars. The motors are capable of equal braking torque as driving torque.
Just think of them as big 1/10 electric cars.

For me the benefits of electric braking are;
1. Way simpler
2. Much stronger braking
3. No fade problems
Yes, I'm aware of that, but it does not seem to be much of an issue. It's really the same as running electric braking on 1/10 scale cars, just scaled up. Nobody runs mechanical brakes on 1/10 scale electric cars.

If these motors have enough power to launch these 8 pound cars from a standing start, then they have plenty of power to slow them down and stop them. If the motor fries as a result of electric braking then the manufacturers need to improve the motors.
Personally I think the voltage you run has more effect on motor temps. I ran 5S and my motor did not even get over 100 degrees... and believe me I was using the brake a lot since I'm the newbie racer.

I see you have the DM-1 with the Tekin RX8 System...I think?? Are you using two speed or or a center diff? What gearing? ....and what diff wt lube are you using? Sorry to ask so many questions. I'm still in the trial an error phase but I gotta say, this beast is fast and when you get a few more together it's crazy.

I agree with your three reasons but I was swayed to mechanical brakes previously and they seem to do pretty well.

Then it dawned on me that if I have to go these two routes then these motors are not yet designed for such a purpose.
Well in fact they are and they do a fine job of handling it all.

Fangs, I almost went the same direction as you did, even was going to run two speed to put less stress on the motor.

How much drag brake are you using if any? What's your gearing?

I'm going to start playing with the motor brakes again and see how it goes but I'm not too keen on the two speed. I had a two speed on something else many years ago and it drove me crazy. Too much hassle. How much drag brake are you using if any? What's your gearing? __________________ Slash 4X4 PE - MMPro, TeknoRC M6 Drive shafts E-Revo Brushless Edition - Mamba Power Baby!!

Drag brake I'll have to check with computer.. I pretty sure it's set to minimum. Current limit is way up though, close to 70% .. then again motor is a 1700 kv.
