12th scale electric is all about corner speed, there is very little need, if any for brakes, especially at stock class speeds.

Since you're new to 12th scale, HERE is a link to tons of info on building and tuning your new car.

btw. Welcome to 12th scale, this is one of the most fun and inexpensive RC classes around
thanks for all the info.

I guess I could live with it, however, one example where I am having issues.
Let's say I am going driving on a fast long straight and start braking at the end, the brakes work well enough to slow the car down, they stop the motor from spinning, however, than the car still moves because there is no resistance anymore from the motor and the car continues to move still too fast for the corner.
I think what you are looking for is "Drag" brake. That is adjustable on the SXX under Mode4.

Start by testing this with another motor... Add some drag brake if you find you need more with specific motor. Different motors do apply different amount of brake.
Saying all that though, for 1/12th no brakes and nor drag brake!!! Only use a little brake incase of emergency...
As someone mentioned earlier, corner speed is important, and set-up so you can come on throttle smoothly but as early as possible out a corner.
This is all with Mod 4.0 / 3.5 T motors... So one thing I learned over the years with 1/12th... Apart from Practice Practice Practice... It is not a TC car, but in South Africa Nationals we have them run faster the n the Mod TC cars

Good Luck!!!

What you are experiencing is normal especially with the 12th.
Don't worry about it and drive you will find that the brakes feel harder as you go faster due tonthe rotating mass. Little speed little brakes.

Hi, it says here at LRP

Rec. Motorlimit Brushless	Forward / Brake
Voltage Input	3.7 - 7.4V
B.E.C.	over 4.5 turns
Dimension	30.5x34x16mm
input voltage	0.011V/phase
Weight (without wires)	30g
TwinBEC	6.0V / 3.0A
Does this mean only 4.5 can be run as minimum?

p.s. What is average turn for 12th


TQ - What is length and width of track and what might be motor (turn) selection for fast pace drivers

Norcal - What is length and width of track and what might be motor (turn) selection for fast pace drivers

Can a 3.5 motor work overall?

Thank you
