Howard..?? Anyone..??

Hope that you and yours are well.

I won a Speed Passion ESC at the Asphalt Assault Race.

I already had a Speed Passion 17.5 Motor (New In Box)
at home...

I tried to hook them up in my son's SC10 with a
Traxxas 2.4 Radio and Rcvr....

It programs "exactly" the way the Directions say,
seems fine, and I get steering but No Motor function.

I have tried different motors, and different receivers.

Any ideas?
