Hi. I cant get either of my 2 program boxes to work with any of my 120amp v3.1 esc. Both boxes work with my just stocks, but not my v3.1's. Any ideas??
Thanks

The justock plugs into the box with the receiver wire, the V3.1 has to use the cable in the box and plugs in to the connector next to the cooling fan. Usually the ESC has to be unplugged from the receiver as well.

Thanks. That must be what im doing wrong. Im trying to plug it in the same way as the just stocks. Thanks
