NOOOOOOOOOOOOOOOOO! WHYYYYYYYYYY? I kinda like it
it’s not my call to make anyways. Not exactly adding a whole lot of weight and this is t a Mugen MBX8R eco…where guys add 30gram weights to balance it lol. but is it actually something a lot of guys do? just ripping out the ebrake?
It’s on ch3
Toss that Hand Brake already dude. It is useless fluff.
Why is it NOT your call anyway??? 
You lost me on that one!
I know exactly what your problem is there. Part of the problem is the manual adjustment and also that crappy RTR 3 channel radio,, along with the crappy Spektrum HB servo doesn't offer any dedicated 3rd channel
"Trimming". It is either full H. brake or not.

Arrmas first mistake.. I can help further, But...........I'll let others explain it for you.
I tossed my HB on my stock heavy 16.25 pound running weight FireTeam. And not because I am saving a stupid 3 grams or whatever. The HB is just Novelty Marketting Fluff with no real practical use at all whatsoever.
Get it out of your system if need be,
then yank it out. At the very least unplug it from the Rx. I hope you weren't enticed buying the V2 Infr just because of this silly HB and are stuck on this Fluff. It is not anything great at all. With a poor design execution.
Just a
BEC amperage Overhead liability at best. Worse case is what you are now having issues with.
You need to read the Radio manual better to understand why it was improperly designed, implemented, and controlled.
That HB ruined the V2 IMHO. One excuse to raise the V2 Infr pricing with some additional Marketting Box art to show off.
You never see any Videos out there with guys using it anyway.
And the speed runner guys will NEVER keep it on the chassis. It gets tossed first thing out the box. Just makes the chassis all bloated. The HB servo alone draws
Idle amps from the
BEC,
whether you use it or not.
I would want the Steering servo and Receiver to get
all the available ESC's BEC amps exclusively. The priority. And the floating HB Disk interferes with the Rear Drive shaft rotating smoothly and Center diff's Rear Output cup.
