Question.. cant get my head around it.
 
How do you use mechinal brake with brushless esc? How do you set it up?

And if i dont use mechincal brake, will BL ESC / motor strong enough to stop the around 5kg truck?

Thanks

There are two ways to use the Mechanical brake. If you have a 3 channel radio, run the brake on channel 3 and use servo mixing with the throttle channel. If that is not an option, use a y-cable on the esc. You will need to disable esc brakes on these as well. Many use motor brakes in heavy trucks without a problem. I use motor brakes in a 5.5kg truck and have no problem. I would make sure you are not at the voltage/current limit of your esc if doing this, leave a little headroom. I am using 6s on a 8s controller to give a little headroom.

u put brake servo on channel 3
you mix channel 2+3
you set channel 2 BR EPA on radio to 0 (so ESC does not do anything when u push brake)
you set channel 3 FR EPA on radio to 0 (so nothing happens when you push throttle)

and on ESC you either disable braking if possible or set it to lowest setting

of course you will loose reverse.

good motor/ESC can stop 5kg truck - my Neu + MGM can stop my maxx without any issues and i have to have brake EPA set to 75% as anything higher is just too much

thanks that sound too much hassle.
I guess i'll lock the tranmission.... that gives lots less friction of not using mech brake.

OH Can i keep my 2 speed instead of removing 1 gear in tranmission and lock it so i can use esc/motor braking.

You don't have to loose reverse with mechanical brakes if the nitro version already has reverse. I used to have a brushless MGT with mechanical brakes, and I kept the 3rd channel for reverse. I didn't have to do any channel mixing, either.

hi

i personally would recommend to lock the transmission in first gear.
we once tested the 2speed in the savage with mechanical brakes. no track runs just bashing in the pit as usual. we had several issues with it so after some month we moved back to the locked transmission and motor brake. much smoother.

bye
