mamba max very weak braking...why?

[blueb8llz]

is it the motor or esc giving my rustler weak braking?
its a mamba max w/ 6900kv motor on 2s lipos geared 55 mph on a rustler with stampede tires.
at first, i thought maybe it's because of the bigger tires, but i put my friends vilenion esc and motor on 3s into my rustler with exact same setup, and the brakes work on a dime.

i could be going pretty slow and the brakes are still weak. i have the brake at 100% and even have 10% drag brake because the braking is soooo weak.
any clues???

maybe the brake setting on the radio?

Is the MM old? Maybe the caps are dead...? Does the motor get hot quickly? If the magnets are weakened then it will heat up quickly AND have weak brakes.

demagnetized motor?

im using the stock radio that comes with the mini rc18, i dont believe it has a brake setting. but anyways, i used this exact radio with the vilenion system and it worked great.

i bought the mm6900 combo used so i dont know the past, but he claimed it only had 10 runs hahah thats most likely a lie.
the motor doesnt seem demagged...how can you tell anyways.
it still has plenty of power, and goes fast..havent gps yet but looks around 45+
the motor does heat up pretty fast cus im geared soooooo high especially with them big o tires. it gets to about 150 degrees in 20 mins. so does this sound like a weak magnet causing weak brakes?
how can i check if the caps are dead?

Try your friend's Velineon ESC with your motor and see if the brakes are better. If not then the motor is probably fried. Keep an eye on temps just in case, so that you don't take the Velineon out, too. You might also try recalibrating the radio to the MM.

maybe the previous owner turned the brakes down in castle link? that might be your problem

[blueb8llz]

good idea to try his vilieon esc but he left now. dunno when ill see him again haha. he lives pretty far from me. so there goes that idea.
so the motor can be fried even though forward and reverse speeds are great.??
i already tried recaliberating the radio. and i have the brakes at 100% on castle link.

What about the braking curve? It's on a different tab all by itself...

reload firmware. it may help.

[blueb8llz]

i have the newest firmware. and the brake curve is in stock form.
o well, doesnt bother me that much, i was just wondering what the problem is.
but i do encounter alot of close calls because of the weak braking.
the funny thing is, i had the same problem when i installed a 6 turn brushed motor with a novak cyclone esc. and that braking power was even weaker haha. and that motor was almost brand new.
so now that i think about it, i dont think its the motors causing this.

My mamba max at 50% braking had enough power to cause my esavage to launch forward and somersault from top speed. 10% brake was wat I used in the past.

Have you tried a smaller pinion gear or different battery? My guess is the gearing is too tall and the motor isn't able to provide the braking force (torque) you desire.

[eovnu87435ds]

+1 for metalMan's idea. try a setup with some stock tires if you have em, and take the pinion down a few teeth if you can.

no something dont smell right. any motor that is not demaged should lock at 100% brake
