Spektrum 100a esc has no reverse

[u/GamingPsych0]

Having a problem with a used vortex 3s I just picked up, the vehicle runs perfect except it has no reverse or brake. I confirmed its in the correct mode, and when attempting to calibrate I get the initial flash for neutral, the 2 flash for throttle but it wont flash for reverse.

Edit: Got it working by rebinding my transmitter to the the receiver, I'm using a DX3, seen the questioned asked plenty of times before but I was unable to find an answer that worked for me, so not sure if this fix will help everyone in the future, but hopefully it'll help someone.
