Preferred linkage for thottle?
Flex cable/ball link.
CA the nut to the back of the throttle arm.
EZ connectors wobble and I can't get a consistent idle.
4-stroke: flex-cable from the servo to a metal clevis driving a bellcrank on the motor mount. Make the bellcrank from an extra servo horn. From the bellcrank use a metal clevis, metal pushrod, and ball link on the throttle arm.
