Strange behaviour when controlling RPM

My Velineon 3500 motor works fine with the VESC when setting the duty cycle. However, whenever I set a RPM the motor goes crazy. For- and backwards randomly. I'm using MIT Racecar configs files for the motor. Those were used before with exactly this motor. 

What could be the reason for this behaviour? I thought maybe the number of poles in the additional info register is wrong, but this had no effect.

Me too, using an assortment of different motors - same problem.

My PPM input is unusable.  I've got a remote-controller that uses UART instead of PPM, and exact same setup works fine with that... so might be a PPM input problem or bug in code relating to that
