Flight
There’s nothing extraordinary that you need to be made aware
of before fl ying the Kunai – it has no unusual characteristics 
and simply does what you tell it. Before fl ying, always 
check control response fi rst to make sure everything is 
operating correctly.
To launch, simply hold the model overhead, apply 3/4 to full-
throttle and give the Kunai a light toss at a slightly upward 
angle – maybe ten degrees or so. Once airborne lower the 
throttle as necessary and trim for straight-and-level fl ight. 
Enjoy fl ying the Kunai while learning its fl ight characteristics 
including stall, spin and spin recovery characteristics from 
a high altitude.
Also at high altitude, extend the spoilerons to see how it reacts.
Until the Kunai bleeds off speed it will initially balloon when 
the spoilerons are extended, but will reach “equilibrium” and 
establish a gentle, slow, gradually descending glide (unless 
rising air is encountered). Add partial throttle, retract the 
spoilerons, and then add more throttle to climb out. Practice a 
few circuits like this to know what to expect when it’s actually 
time to land.
When your timer sounds and it’s time to land, extend half
spoilerons on the crosswind leg, turn onto base aligning 
the Kunai with the landing zone and extend full spoilerons 
whenever necessary. Continue feeding up elevator until all up 
elevator has been applied and the Kunai gently touches down.
