Control surface adjustments: Adjust rudder parallel with vertical stabilizer and set position by tightening set screw in EZ-
Connector. Adjust elevator parallel with horizontal stabilizer and set position by tightening set screw in EZ-Connector.
VERY IMPORTANT: With the wing seated in fuselage adjust aileron parallel to angle of top side of fuselage.
Under no circumstances should the ailerons be centered flat with the bottom surface of the wing.
If using a computer radio set control surface throws to those recommended on the plan sheet. We suggest a starting
point of 30% expo to smooth out your control of the sticks. Cut all push rods down allowing only ½” additional length
beyond the ez-connector at each servo.
Motor and propeller mounting: Mount the Hacker A30-16M, VSport 350, or E-Flite Power 10 using the radial mounting
hardware included with your motor package. Note the spacing on the 4-40 blind nuts has been established for the Hacker
A30-16M using any other motor may require slightly elongating the holes in the motor mount hardware. Secure the motor
to the firewall using the provided four (4) 4-40 x 3/8” machine screws (thread-locking compound on these screws is highly
recommended). Proper down thrust is built into the firewall. Two 1/16” plywood washers are provided in this kit to shim
the left side of the motor (as viewed from the cockpit) to achieve proper right thrust. Place both ply washer under each of
the two left side motor mount arms. Right thrust will vary with your power system selection but we have found that with
the recommended Hacker A30-16M and 11x5.5 propeller one 1/16” shim is typically about right. To reduce right thrust
simply remove the shim and reduce it’s thickness through sanding.
Install your balanced propeller to the motor. Never run a propeller assuming it is in balance without checking it first.
Never run a propeller that is known to be damaged, repaired, or out of balance. Never run a motor with a bent shaft. In-
flight vibration from out of round and out of balance components will cause pre-mature failure of airframe and electrical
components. If you are un-certain how to balance a propeller, seek advice from an experienced hobbyist or your local
hobby retailer.
Mount the wing: Prior to mounting the wing you’ll need to fit and install the wing retention tabs 1/16” plywood parts LE3 to
the wing leading edge. First, verify that LE3 readily fits within rectangular notches of former F2 adjust thickness as
required so that LE3 easily slips in and out of this notch. Next slot your covering at the wing leading edge where LE3
installs. Seat LE3 into position as illustrated below. Again, test the fit to the fuselage, adjust fit, and retain parts by
wicking thin CA around slots holding LE3. Note that covering has been omitted for clarity in the photo below.
Retain wing to fuselage using four (4) #33 rubber bands two (2) on each side of the fuselage. Use fresh rubber bands
prior to each flying session. DO NOT cross the rubber bands, use bands of greater size / thickness, or exceed six (6)
rubber bands (three per side) as this will prevent the wing from cleanly departing the fuselage in the event of a crash.
