I have a Arrma Typhon, with a SRS-4210, and it wont drive reverse. I keep hitting reverse multiple times and 90% of the time nothing happens. Than when I let go once in while it will slow drive backwards on its own. When i set it up obviously i tell the radio its reverse capable. Im ready to eBay this thing. Reverse works fine on my DX4S. What the heck am I doing wrong?

try recalibrating
