Joe--after having spent a lot of time with the Russians in Romania with motor ramp curves ramps and how to get the most from them I now think that the "simple" ramps are not going to get the best performance from the props. I can set different ramps in the transmitter depending on the flight condition--bet you can't do that with the controller based ramp! I don't object to you running the simple ramps since that makes it all the easier to beat you
It was clear in Romania that people are moving to higher voltage setups. There is really little or no difference in equipment costs for the systems. A ICE 200 costs the same as a ICE160HV.
