TRIMMING SET UP & FLYING NOTES
Boomerang SPRINT is not tricky or difficult to set up.
Set the Centre of Gravity no less than 10” (255 mm.) forward of the
Trailing Edge for the first flights.
Start with 5/8” up and ½” down Aileron (16 & 13 mm.). Elevators 5/8”
(16mm) up and down. Adjust later to your personal preferences.
The flap is very effective in slowing the glide speed. Set it up to drop
as far as possible, to act as an airbrake. If you can add crow braking
starting from half flap to full flap, to raise both ailerons about 15 to
20 degrees, the slow flight and the descent rate on the approach is
remarkable, with full control at very low airspeeds using slightly
open throttle allowing a high angle of attack with virtually no risk of
dropping a wing.
Mix in 10% down elevator with the flap movement to prevent the
nose rising as it is applied. If you have advanced mixing, this should
return to zero from half flap to full down flap.
SPRINT is capable of any aerobatics you care to try, including spins
both upright and inverted, snaps, tumbles, rolling circles and loops,
knife edge and very slow flight.
The fuel tank custom made by Sullivan for us will give up to 15
minutes of flying time. It can, of course, be only partially filled for
shorter flights if you prefer.
You should enjoy some good flying fun with the Sprint, just about
the most stress free jet flying you can get! Feel free to
