Default question about brakes/delay

I have a hpi wr8 and hoping someone could help with a question. When I go from reverse to forward the car brakes and I have to release the trigger and hit it again to make it go forward. Which I like. However going from forward to reverse there is no brake or delay. It just slams right into reverse... I can't imagine that being good for the gears.

Is there away to make it so I have a brake while moving forward? So I don't have to drag brake or slam it in reverse?

Thought maybe some one could help me out.

Thanks

The HPI Vapor esc is actually a rebranded Castle Creations Sidewinder SCT esc. The Sidewinder does have a mode where when you hit the brakes it will brake and then you have to go to neutral on the trigger and back to brake/reverse in order to go in reverse. Unfortunately HPI dictates the firmware in the esc's Castle makes for them and I'm not sure if the HPI version supports transmitter programming like the Castle Sidewinder SCT does. The HPI version does support using the Castle Link tomconnect to your computer for programming where you will be able to change the mode as well as other settings like punch, braking force, reverse speed, throttle curves, etc.

Ahhhh common problem....

if u have brakes in reverse but not going forward that means it's setup backwards

so what u need to do....
Reverse channel 2 on the controller, this will correct the brakes, but it will make the car run backwards when it should be going forwards so u need to reverse the direction of the motor, it's done by swapping wires for sensor less motors and a .program card for sensored setups....

providing u do both those steps, u will have normal braking again

I think I may understand what you're talking about. I want to switch what I have numbered on the picture. I want to switch 1 and 3 around then reprogram my transmitter and see if that fixes the issue. The next question I have .... can those wires that I labeled "1, 2 & 3" be pulled directly up and and out to be switched? Pull from the end of the black or pull up on the gold? I don't want to ruin anything.

Switch 1 and 3 and pull from where the black ends. The gold stays on the ESC. They are bullet connectors, so you will be pulling the bullet out of the socket.
