It is vitally important that the throttle operates correctly and does not bind at either end of its
travel. Switch on the radio and centralise the throttle stick. Holding the throttle barrel at its mid
throttle position, nip the grub screw tight in the pushrod connector. Use your transmitter’s end point adjustment - EPA/ATV
- (or adjust mechanically) so that the throttle opens and closes as shown in the diagrams below
Stage 6
Remove your engine’s prop nut and washer. Install the spinner backplate followed by your
propeller. Use the moulded pegs to align the propeller so that when the propeller is in the
correct position, the spinner cut-out will align correctly with the propeller. Re-fit your prop washer and nut, then tighten. Fit
the spinner nose with the two screws supplied.
