plug on the fi ll line. It’s a good idea to add an extension to the vent
line as shown, that goes up and to the rear of the tank. This helps to
avoid draining fuel from the tank when the model is pointed down.
4. Install the throttle servo at least 12" [305mm] away from the engine.
Make sure that you get both carburetor’s full range of rotation with
your servo travel. Be sure to use a non-metallic linkage with the
included 6-32 link. A high-torque heavy duty metal gear servo is
recommended to operate the throttle on the DLE-222.
5. Control of the chokes will be necessary during start-up and
operation. Make sure you have manual access or control of the
chokes via a servo or mechanical linkage before completing
installation of the DLE-222.
6. Connect the ignition wires from ignition modules to the spark plugs.
7. Install the muffl ers onto the engine with the included gaskets.
Tighten the four bolts on each muffl er evenly to ensure a proper
seal. Be sure to use thread locker and that the ignition wires do not
contact the muffl ers.

exhaust holes in the cowl.

Drill and Install the Propeller
The easiest way to drill the propeller to fi t the hub is to use a drill guide.
If you do not have a drill guide, you can use the following method to
drill your propellers. Most propellers within the recommended size
range have a 0.393" [10mm] center hole pre-drilled. If your propeller
has this predrilled hole, move on to step 3. If not, start with step 1.
1. Remove the cowling from the aircraft. Use the included propeller
washer to mark the centering hole on the propeller
2. Once the location is established, use a drill press with a 13/32"
(0.406/10.31mm) drill bit. In order to achieve a clean hole opening
