HAND TAKEOFF
It is advisable to have a helper for the first hand launches. Hold the airplane behind the wing with the throwing hand and support
the nose with the opposite hand. Run motor up to full throttle and give a firm throw straight ahead. The aircraft should be launched
firmly with the nose up 5 degrees and directly against the wind. Do not throw with nose down.
TAKEOFF FROM SURFACE
Put the aircraft on the runway. Avoid sharp turns when taxiing at higher speeds to avoid tipping the aircraft on its side. Hold 1/2
full up elevator at the start of the take-off to get weight off the nosewheel and allow for smoother take-offs. Steer with the rudder
and as speed increases, reduce the up-elevator input to 1/4 to 1/2 up elevator. The airplane will lift off when flying speed is
reached.
LANDING
ATTENTION: Always lower the throttle after landing to avoid accidental intake of materials, which could result possible demage to
the rotor and/or motor and cause personal injury.
REPAIR
Thanks to the EPO-foam construction, repairs to most foam can be made using virtually any adhesive (hot glue, regular CA, epoxy
etc.).
