CONNECTING THE THROTTLE LINKAGE
1. Use the provided ball-link to attach the throttle linka
ge to the throttle arm on the carburetor.
2. Power ON the transmitter and receiver. Move the
throttle stick and throttle trim to center.
3. Place the servo arm on the throttle servo so the arm
is perpendicular (90°) to the throttle linkage.
4. Ensure the throttle servo is moving in the appropriate
direction. The throttle servo arm should move
towards the fuselage when the throttle stick is moved
to high throttle. If it doesn’t, reverse the servo
direction in your transmitter.
5. Move the throttle stick to low throttle on the trans
mitter. Reduce the throttle trim to its lowest setting.
6. Move the linkage connected to the carburetor to full-
idle. On the servo arm, find the hole that is closest to
12mm (1/2 in) from the center of the arm. Mark the
pushrod where it meets this hole.
7. Using pliers, bend the pushrod so there is a 90° bend at the mark.
8. Using a pushrod keeper, secure the pushrod in the servo arm.
9. Check that the throttle arm on the carburetor can travel fully open and fully closed (both
have hard stops). Adjust your transmitter endpoints to ensure full travel.
10. If there is a large difference between the endpoints, adjust the endpoints and sub-trim to
find a balance where the endpoints are within approximately 10% of each other.
CONNECTING THE ELECTRONIC IGNITION
The electronic ignition requires a voltage input of 6.0—8.4VDC. We recommend a 2S Li-Po battery.
The maximum current draw at full throttle is 650mA, and average current draw is 325mA.
BASELINE NEEDLE SETTINGS
The baseline needle settings
for your engine are 1.5 turns
out for the high-speed needle,
and 1.75 turns out for the low-
speed needle.
To adjust the settings, screw
the needles in by rotating
them clockwise. They will seat
gently— do not force them,
this could damage the needles
or carburetor body. Open the
needles the number of turns
listed above.
