FINAL RADIO SYSTEM INSTALLATION
1. Whether you 72 MHz systems or the newer 2.4 GHz systems, proper radio
installation and care is vital to the safe and reliable operation of your aircraft.
Follow the manufacturer’s instruction for installation guidance of receivers and
batteries paying attention to factors such as vibration isolation, adequate cooling, and
clearances.
2. Mount your reciever(s) securely in a location which provides a clean and
maintenance free solution to your setup. All servo wires should be neatly routed and
secured in place so they will not come loose or flop around during flight.
3. The fuselage ply sides provide space to mount your switches just below the
canopy. Mount your switches according to the manufacturer’s instructions and route
your wires safely and securely as above.
4. Your receiver battery(s) can be mounted in a variety of locations depending on
your balance needs. Regardless of where you mount your batteries it is vital that
they are very secure with no possibility of coming loose. Use double sided velcro to
hold the batteries from sliding around and then use zip ties or velcro straps to secure
them tightly in place.
5. Servo and battery leads are the life blood of your aircraft. Make sure all wires
are top quality and connectors are tight and display no loose pins or frayed wires.
Servo clips are provided in the kit for your convenience. These servo clips can even
be glued to the wood structure using CA if desired.
6. Check all radio programming and control surface operations thouroughly before
your initial flight. Check your radio range according to the radio manufacturer’s
instructions both with the engine off and running.
BALANCING and PRE-FLIGHT
1. Most state of the art aerobatic aircraft allow for a wide margin for balancing
depending on what level of precision or freestyle the pilot prefers. To perform
properly without being too pitch sensitive, you must not go too aft on the
CG.
We recommends an initial CG setting of 4.2 – 5 inches
（
107-127mm
）
behind the leading edge of the wing at the root. More experienced pilots may
want to set the CG further aft for more 3D capability. Varying weights of
engines and radio gear will dictate how you should install each. The batteries can
easily be located pretty much anywhere in the fuselage.
Note: The best way to check your balance is to trim for level flight at about 1/2 to
3/4 throttle and then roll inverted. The aircraft should maintain level flight with very
little to no down elevator input. If the aircraft climbs when inverted then you’ve
probably got your CG too far aft. If the nose drops more than slightly, then you are
most likely nose heavy.
