Hi Guys,
My LST is almost done, but I never had so much wiring in my car so I'm a bit confused

First of all the set-up of my LST:
- Brushless motor
- ESC
- BEC
- 5S LiPo
- 2 Steering servos
- Mechanical brake servo
- Receiver
I will set the brake amount on my Quark at 0%, but how can I brake mechanically by pushing the throttle stick backwards? (Like it normally should be)
I've got awesome painting skills so I drawed something
Could anybody answer my first question please? And I've got another question; does all things in my drawing are right?
Thanks,
Patrick
