Speaking of the conections to the carb for the ZDZ 80, I have a question. I haven't owned a gas engine before with a choke plate that needed to be servo operated. The choke on the ZDZ 80 carb has a major detent that it snaps over on the way from open to closed. Does this need to be altered somehow to allow the servo to operate the plate smoothly? It would seem that there is enough resistance to put most standard servos in a stall situation. If it needs to be altered to operate smoothly what is the process to do so?
Vince,
The detent you speak of should not pose any problems. But one should use a good servo on the choke and the throttle.
We tend to think that we can easily use elcheapo servos for these, but the throttle servo is used as much as any control on the airplane and you do need precision on the throttle.
