5. Prior to mounting the engine we strongly suggest using a lightweight fiberglass or carbon fiber cloth
with resin to provide extra strength to the firewall mounting. This can be done easily by laying the
cloth across the firewall and down the sides of the engine box about 4 inches.
6. Cuts holes as required for fuel tubing, and connect the tubing to the engine and route the vent line as
necessary. Determine your throttle servo location and cut holes as necessary for the throttle push
rod, and install your throttle servo.
7. Cut holes in cowl for muffler exhaust pipes and install cowl. There are 4 bolts that are used to bolt
the cowl ring to the fuselage. The two top bolts are bolted using the aluminum angle that is bolted to
the motor box, and the two bottom bolts are bolted from the front of the cowl ring, reaching in from
the exhaust hole at the bottom of the cowl.
NOTE: For canister exhaust or tuned pipes use a 90mm drop header and we recommend
either MTW or KS exhaust systems.
Initial Set-Up
1. Now, with everything on the airplane such that it is practically ready to fly except for the wing
panels and wing tube, check the initial CG using the method described below. Note that this method
does not actually determine the actual CG, but a balance point, which, when the wing panels are
installed will place the CG at a good position for initial flights.
2. Thus, with the wing panels and wing tube off, lift the aircraft with your fingertips at the wing tube
socket on both sides of the fuselage. The aircraft should balance level, or with the nose just slightly
low.
3. Initial control throws are as follows:
When setting your throws we recommend using CRC or similar throw meters.
Aileron: 25 degrees up and 20 degrees down for low rate
40 degrees up and 35 degrees down for high rate
Notice:
We recommend a 5 degree difference between your up and down throws when setting up
your Ailerons, this will allow you to have a more axial roll.
Elevator: 12 degrees up and down for low rate
35 degrees up and down for high rate
Rudder: Aprox. ½ of max available throw for low rate
Full available throw for high rate
4. Recommended initial mix ratios:
10% up elevator with either left or right rudder
2% right aileron with left rudder
2% left aileron with right rudder
