Interesting. The reverse setting shouldn't affect the brakes, because the brakes operate by just disconnecting the battery and short-circuiting the motor to itself. The braking strength is regulated the same way the acceleration strength is, by PWM-ing the motor connections thousands of times per second.

As already mentioned try reducing the timing slightly, I have found the more timing on the motor the weaker the brakes are, adjusting down by even 2/3 degrees can make a big difference

Thanks for all you answers. So according to you ESC brand has nothing to do with brake strength.
I've a national race this week-end... I won't be able to try a tekin or LRP esc... But I will test all the other tips.

I'll keep you up to date

I race R1 wurks V16 motor with a 1650+ rotor, and a gear ratio between 4.2 and 4.5 (huge tracks)

I tried different speedo : Orca B32, SkyRC TS160, R1Wuks Digital2, HW XR10
I played with settings : initial brake, brake frq, brake strengh, etc... but I always find that the brake feeling is not good.... sometimes too weak, sometimes not linear...

So experienced drivers... what are you advices?
Which speedo is the best for TC stock racing ? which firmware version?
Does the condensator have any influence?

Thx for your help
I've tested many spedoo racing in STOCK 13.5 BLINKY class, but only one have a real brake... LRP FlowX with Stock FW!

Completely agree that it shouldnít, but for some reason it does (at least on the older justock ESCís) Itís definitely something I wouldnít have looked at without some else pointing it out to me a while back. Itís one of those odd things that couldnít hurt to test.

I think ESC brand has a lot to do with brake strength. Suprised the XR10 did not work for you, those supposedly have one of the strongest brakes.

I wonder if they bodged-up the firmware so the maximum PWM setting for reverse also affects the maximum PWM setting for braking -- like, if you have reverse set to 75% and braking set to 75%, braking is actually limited to 75% * 75% = 56%.

If you're running in a blinky class, then it doesn't matter whether you buy an ESC that has lots of adjustments, so the cheaper one would seem to be better. However, the power capacity and the efficiency of the MOSFET transistors are both important, so double-check those specs before buying.

Yes power capacitors and mosfet transistors are important, but so is drive frequency, punch control and a decent esc fan to keep everything cool.....

I don't know anyone who runs an ESC fan for blinky. It's just unnecessary weight.

I usually run a fan on all my esc's no matter what motor I run and I also double the esc capacitor if it can fit the car.....

If you removed the muffler bearings from your tc4, you would have a lot of room.
