Attaching the Propeller and Spinner
Remove the prop nut and prop washer from the engine.
Install the spinner back plate. Install the propeller, the
prop washer and then the prop nut in that order (see
photo). Securely tighten the prop nut using an adjustable
wrench. Install the spinner cone.
Starting the Evolution Engine
Fuel
The Evolution Engine comes pre-run and adjusted from
the factory. We recommend using high quality Cool Power
Omega, Hangar 9
®
AeroBlend
or Power Master fuels
containing 10 to 15% Nitro. The Evolution Engine has
been test run using these fuels. If another brand of fuel
is used, it may be necessary to slightly adjust the needle
valves to compensate for the differences in fuel.
Glow Plug
The Evolution Engine comes with a specially designed
Super Plug that prevents idle and transition flameouts.
The plugs unique shape directs incoming fuel/air mixture
away from the plug element. When replacing the plug,
be sure to replace it with another Hangar 9
Super Plug
(HAN3011).
Starting the Engine
Step 1. Fill the tank with the above-mentioned 10 or
15% fuel.
Step 2. Reattach the fuel lines, making sure the vent
and clunk line are attached to the fuel nipple
and the muffler pressure nipple.
Caution: Do not attach the glow driver yet.
Step 3. With the throttle fully open, place your thumb
over the carburetor and rotate the prop clock-
wise through 6 complete revolutions, thus
priming the engine.
Step 4. Close the throttle to the idle position and have a
helper hold your airplane.

Select a servo arm that has a hole located 11mm or
7/16" out from center and attach the other end of the
throttle linkage. (see photos below)
With low throttle and mid-trim (idle position), the throttle
barrel should be open 1mm, giving a low rpm idle (see
photo above). Adjust the length of the pushrod until the
throttle barrel is exactly 1mm open. Check to be sure
the servo is moving in the correct direction. Full throttle
should open the throttle barrel fully, while low throttle,
low-trim should completely close the throttle barrel.
Reverse the servo throw if necessary.
Note: It may be necessary to slightly adjust
the length of the throttle pushrod to achieve
the correct mid-trim, low-stick idle position.
Attaching the Fuel Lines
Using medium silicon fuel tubing, attach the fuel tank’s
clunk line to the fuel nipple. This line will supply fuel to
the engine. Attach the vent line to the muffler pressure
nipple. This line pressurizes the fuel tank with the muffler
pressure, creating consistent fuel flow, regardless of the
airplanes altitude.

Vent Line
The Hangar 9 START KIT (HANSTART) includes everything needed,
except fuel and starter, to get the Evolution Engine running.
At low throttle, mid-trim, the throttle barrel should be 1 mm open.
