Just got my new Pro DSM setup, switching from FM... What I find interesting, is when you turn on the RX (with out the radio on), the wheel are spinning forward, slow but going forward, I turned on the radio and the same thing, so I had to go into the throttle settings and put brake into it to stop this (about 8 clicks). I have two cars, one with a LRP Q2 and the other with a LRP sphere. Both are acting the same with to different RX units, both DSM RX units are the Pro.

Is this normal?
What am I missing?
Do I need to reset my speedo?
