lrp sxx wont change profile

[lukewheels]

Has anyone else had this issue? The motor runs at one speed regardless of profile 1-10. I've swapped sensor lead, board, reciever, transmitter, unplugged servo, reset end points, battery swap, the only change i get is one fast burst after setting end points then back to one speed. Any ideas? Last nights racing was hard work when running flat out!
