TEST FLIGHTS: TRIMMING FOR STRAIGHT AND LEVEL FLIGHT
1.
Locate a flat, open, grassy field for initial test
flights. Choose a nice day with a light breeze
(no more than 5 mph).
2.
Turn on transmitter, then glider. Check controls
and flight surfaces for proper operation. If you
are unsure, start with "Low Rate" elevon
deflections listed on page 13.
3.
As shown, use simple, overhand javelin-style
launches until you achieve proper trim. Pinch
sides of fuselage in front of wing with middle
finger and thumb, supporting rear of glider with
index finger.
4.
ALWAYS launch and land your glider into wind
to minimize ground speed. Throw the Alula-TREK
firmly but not excessively, like a javelin, without
twisting your wrist. Make sure to point nose
towards horizon (not up or down). Make trim
adjustments via trim levers on your transmitter
until glider flies straight and level.
5.
Once you have achieved a straight and level
glide, you can progressively try harder launches
and eventually side-arm launches by utilizing the
method described on Pages 17-18.

HOT TIP: PREVENT LOOSE CLEVISES
It is possible for the clamping action of the
clevises on the pushrod to loosen after
numerous flights and several hard landings.
Once the glider has been flown and trimmed
to you liking, we suggest adding a drop of
instant glue (CA) to the clevis/pushrod to lock
the pushrod in place. DO NOT get any glue
on the clevis pin and control horn connection.
