Default Speed control delay

My son's Hobbywing v2 speed control has a problem. After reverse, there is a slight delay before forward engages. Anyone know why this would be ?
Thanks

Often a small delay is meant to not strip gears or burnout motors. From reverse to forward seems odd though. I'd probably check the radio settings or start from scratch by resyncing the ESC to the receiver and resetting it too.

This sounds like the correct answer...

Is it sensorless? maybe you have the direction reversed on the speedo/radio and wires swapped from speedo to motor?

There is often a delay in both directions built into an ESC. From reverse to forward especially because that is what most people use to try and get an RC car to pop wheelies which inevitably leads to a stripped gear. Typically from forward to reverse the ESC will go into braking mode before it will go into reverse so you get a delay there as well.

It's supposed to do that so you don't abruptly go fwd/rev and strip gears.

Thanks for the responses. Understand about the stripping of gears, but I've never seen this delay before. It's a sensored set up. I did re-calibrate the esc, but its still the same.

We also found the delay with other HW ESCs when large amounts of drag brake and/or after heavy braking. Solution at least for us was to just use forward only and no more delay.

It'll always be that way.

most hobbywing esc give you the option to make it go from forward to reverse instantly through programming but this is only used for rock crawling.

Thanks for the help guys. I've had other Hobbywing esc before, including sensorless ones, Speed Passion and Turnigy ones, but never a delay such as this. It does have 10% drag brake, but I've always used that. I'll try no drag brake and see what happens.

This is normal functionality. The justock acts the same way but the v3 and v3.1 does not. Tapping the brakes 2x in a row will trigger the delay.
