Re-check the center of gravity, move the battery position if necessary so that it balances in a very slight
nose down attitude somewhere near the forward mark (65mm). Check that the linkages and pushrods
are secure, the propeller is secure and the wings are correctly attached.
Switch on the transmitter with the throttle closed and the throttle trim fully down then connect the flight
battery. Check that all the controls are working freely, no binding and that they are working in the
correct sense, ie, aileron stick left (left aileron goes up), elevator stick back (elevator goes up), rudder
stick left (rudder goes left). To arm the stabilization system you need to open the throttle to a low
setting for 1 or 2 seconds then close the throttle. Now pick the model up and check to see if it is in
beginners mode or advanced mode. To do this move the nose up and down with the battery hatch off
and watch the elevator servo movement. If it's in beginners mode the servo will move quite a bit, in
advanced mode the servo will move less. Set the stabilization system into beginners mode then check
that it is working correctly by doing the following test. Roll the aircraft to the right, the left aileron
should go up and the right down. Roll the aircraft to the left and the right aileron should go up and the
left down. Move the nose down and the elevator should go up, move the nose up and the elevator
should go down. Move the nose of the aircraft to the left and the rudder should move right, move the
nose right and the rudder should go left. If all works correctly then you are ready to fly.
So for which ever level of skill you are select the appropriate flight mode. Place the aircraft on your
take off area pointing into wind. It is best to use either a tarmac area or an area with very short grass,
long grass could cause it to nose over. Re-check the controls are working correctly then hold in some
up elevator, gently open up the throttle and correct any swing using the rudder, with a clockwise
rotating propeller the tendency will be to swing right so some left rudder may be needed. As the model
accelerates ease off some of the up elevator so that the tail rises and the model is running on its main
wheels slightly nose up. When full power is reached the Mustang will take off very smoothly, climb out
gently, do not try and climb too steeply, the whole time keep it pointing into wind, do not allow it to turn
(in beginners mode the stabilizer will help keep the model flying straight). Climb up to a safe height
then throttle back to about half or just over. When at a safe height and upwind you can practice some
gentle turns left and right, do not try and turn too steeply at first if you are inexperienced. If things start
to go wrong, close the throttle a bit more and centralize the ailerons and elevator, the stabilizer will
then fly the model for you in a steady straight line.Once you have regained your composure gently
turn the model back to overhead the take off area.
Once you have settled down and are happy doing very gently turns then it is time to think about
landing. Try and fly a nice circuit around the landing strip at about 100ft so that you end up slightly
downwind of the landing area pointing into wind. Gently close the throttle to a point where the model is
descending nicely, not too steeply and keep the wings level (the stabilizer will be helping you with
this). When the model is about 5ft from the ground close the throttle completely, at about 2ft from the
ground apply a small amount of up elevator and just hold it there and the model will gently flare and
land. If all is well and as the model slows on the ground feed in full up elevator to keep the tailwheel
on the ground. To taxy back keep full up elevator in and gently use the throttle and the rudder to steer
the model back.
