Dale. I have always questioned the use of this chart. IMO when one sets up this way you will have close to full RPM by the time you hit half stick. My question for you is if you are running at full stick and back off just a tad do you see an RPM decrease? I have always set up my gassers so that the throttle servo has equal travel above and below 1/2 stick. Then I set the pushrod length so that at half stick the carb butterfly is approx 1/2 open. Any other adjustments are easily accomplished with a throttle curve on the TX. The goal is to slow the application of throttle from 1/2 to full in order to sperad out the throttle response over the whole stick movement. I think the chart defeats this. The benifit I do see with the chart is that the power comes off idle slowly and that can be of use for a newbie but it wrecks the rest of the throttle curve.
