Flight Preparation
■Make sure you have the right model programmed into your transmitter
■Check the direction of each surface not and also right before you take off .
■Remember nothing wrong on the ground ever improves in the air
■Check the air plane with the engine running and do a range check with
■your body between you and the plane at least 150 feet.
■Check your battery voltage after each flight, in case one servo is draining your
battery
■Recheck all screws ,horns and linkages for slop after your maiden fight and
check for damage if you made a bad landing you first time
■Have an experienced pilot fly it for you the first time if you have any doubts in
your mind about the maiden flight
■Take a break after you first flight and let the adrenaline burned off by bragging to
your fellow members how good it flies
■Fly low and at a medium speed on your first few flight
■Listen to your engine run and have an observer with you to remember what you
talked about during the flight or if you get into trouble . Always balance your props,
vibration is a killer.
■Remember nose heavy airplanes fly all the time, tail heavy airplanes fly only
once. Be on the CG!
■Flying two mistakes: high in the beginning and not close to people, planes or
runways. Being a center of the runway hog does not endear you to many modelers.
Double Check
Double check that all screws are installed, all components tightly secured, batteries
and or fuel tank are full, all surfaces are working in the correct directions, balance is
correct and range test passed before performing your maiden flight.
WE WISH YOU A SUCCESSFUL MAIDEN AND MANY HAPPY FLIGHTS WITH
YOUR NEW MODEL
