CONTROL THROWS
We recommend the following CONTROL SURFACE
THROWS:
NOTE: Throws are measured at the Trailing Edge of the
elevator and rudder. These control surface "throws" are
approximate and provide a good starting point for the first
flights with your SPECTRA. You may wish to change the
throws slightly to provide the control authority that you
prefer.
ELEVATOR: 1/2" up, 1/2" down
RUDDER: 1-1/2" Rt., 1-1/2" Lt.
Move the pushrod wires (Z-bends, nylon clevises) in
or out on the control horns and servo horns to achieve the
desired movements. If your radio is equipped with' 'endpoint
adjustments" you may set the throws from the transmitter.
FINAL HOOKUPS AND CHECKS
D 1. Install your flight battery. We recommend you use
a 7 cell battery for maximum performance, but a 6 cell battery
will provide adequate performance under most conditions.
Neatly tuck all of the wiring into place. The plans and the
photos show a fairly neat way of routing everything.
NOTE: If you are using a 7-cell battery you should replace
the 20 amp fuse supplied in the holder with the 25 amp fuse
provided.
D 2. Make sure the control surfaces move in the proper
direction as illustrated in the following sketch.
