Throttle Linkage, Needle-Valve Extension - O.S. engine FL-70 Owner's Instruction Manual

THROTTLE LINKAGE
Before connecting the throttle to its servo,
make sure that the throttle arm and linkage
safely clear any adjacent part of the airframe
structure, etc., as the throttle is opened and
closed.
Connect the linkage so that the throttle is fully
closed when the transmitter throttle stick and
its trim lever are at their lowest settings and
fully open when the throttle stick is in its fully-
open position..
Carefully align the appropriate
throttle arm and servo horn so that they move
symmetrically and smoothly through their full
travel.

L shape, insert it into needle's center hole and
secure it by tightening the set-screw in the
