Flying the H-King Floater Jet
First thing is to double check that the center of gravity is correct and also check that the controls are
working in the correct direction. When you move your aileron control stick to the right the right
aileron should go up and the left one down. When you move the stick left the left aileron should go
up and the right one down. When you move your elevator control stick down the elevator should go
up and when you move the stick up the elevator should go down. The rudder control is
straightforward, left rudder stick is left rudder and right stick is right rudder.
Wait for a day with light winds and find a large grass area clear of tree's, wires, away from roads
and buildings and free of spectators, a helper is good to help you launch the Floater Jet. Switch on
your transmitter with the throttle closed and connect the flight battery, check the controls are
working correctly and in the right direction as above and that all control surfaces are neutral. It is
always good at this point to do a range check of your equipment to check that everything works as it
should do. Get your helper to hold your model at about waist height while you walk away working
the flying controls. It is good to check the motor as well when you are a distance away from the
model to check that it does not interfere with the radio signal and give you glitching servos. Please
make sure you warn your helper before doing this so that they keep themselves well away from the
rotating propeller.
Once satisfied everything is working as it should you are now ready to do some test gliding. Get you
helper to hold your model just above head height and facing into wind, they need to give the model
a firm throw with the nose slightly down, do not have the motor running for this exercise. The glide
should be long and flat with no tendency to turn. If it dives slightly then apply a small amount of up
trim on the transmitter and try again. If it raises its nose and gently stalls then you need to apply a
small amount of down trim. Keep doing these test glides until you get a long flat glide. If the model
has a tendency to turn left or right then apply either some aileron trim or rudder trim in the opposite
direction to the turn. Once the model is trimmed nicely do some practice launches and try doing a
gentle S turn into wind while it is gliding just to get used to the controls.
Once happy with the test gliding you should now be ready for some gentle flying with power. Once
again get your help to hold the model just above head height and into wind and when you are ready
apply some power, do not apply full power as it is not needed, half or just over is more than
sufficient. When you are ready ask your helper to launch the model, if trimmed correctly it should
climb away nice and gently with no tendency to turn. If it does try to turn use the ailerons to keep the
wings level and the model flying straight into the wind, the climb should be gentle, do not climb too
steeply or it may stall and spin or spiral into the ground. Once up to a safe height and well up wind
throttle back slightly until it stops climbing but not so much that it starts coming down. At this point
check the trim of the model, let go of the aileron and elevator stick and watch the model, any
tendency to turn or climb or dive then adjust the trims as necessary. The elevator should be fine if
you did the test gliding correctly, the model will climb under power, this is normal and when you
throttle back in should go into the long flat glide that you trimmed for. Between quarter and mid
throttle somewhere it should maintain its height and fly leve
l, you may need to keep adjusting the
throttle to maintain level flight depending on the weather conditions.
