Well, on the Dle I tried to set up the throttle for the mid position of the carb arm at neutral on the servo and then adjusted both end ATVs to get the required result. The required result being 8000rpm at WOT, 4000rpm at neutral and 1700 or so at idle with carb closing to throttle cut. But with the onboard tach, I had to add nearly 100% expo to get that. Then, in the landing approach, I kept 15% power (to prevent the bounce due to too low an airspeed, this is an over weight glow conversion). Controlling the sink, when I would add power to maintain altitude, there would be a sudden increase in RPM and the airplane would gain height. That would force me to go to idle and then the airplane would bounce due to either overspeeding or stalling beforehand. In 7-8 weekends with 3 flights each time, I had only a couple of satisfactory landings.
A colleague on the field also tried to setup the same way but they tried to do it without expo but with the engine running to get the 4000rpm adjusted using the e-z connector on the throttle. That day we were both struggling with understanding the interface on the 8FG and we didnt get it right and gave up. Subsequently, with the 12FG I never got to try it. Since you cant see the carb opening in gas, it is difficult to setup the throttle like in glow. Another variable was the idle stop screw and the needles. When I tried to adjust the LSN from factory settings after a gallon of fuel, it went up to 4000rpm at idle. Had the idle stop in then, next time I tried it with the screw removed, it hit 4000rpm while no one was holding it (my left had was firmly stuck in the fuse as I always do whether or no someone is holding the airplane, so it didnt budge) and I had quite a scare trying to get to the ignition switch with the 16x8 running. Needless to say I didnt try that again
I know there is a writeup from Jedijody on throttle linkage geometry, I tried it, but setting up the geometry like he showed didnt give me the servo movement at idle to have the throttle cut working properly. I did do the setup with all trims at neutral though.
Did I do something incorrect?
