Tighten the wing membrane by opening the overflap, then grasping the dacron FLAP at the
wingtip and giving it a quick tug to pull it loose from its adhesive. Don't worry, the adhesive is
pressure sensitive and it will stick back after adjusting. Once you have the flap un-attached, pull
the dacron sleeve slightly along the span of the wing towards the wing tip no more than about
1/4 inch. Re-cap the wingtip flap around the spar tip tightly and apply pressure to it to hold the
new position. Tightening this wing will give it more thrust. If you notice any excess tension in the
opposite wing indicated by taughtness and tension wrinkles, that wings tension can also be
relieved by uncapping its wingtip flap and relieving its membrane tension. Loosening the other
wing will give it LESS thrust. The objective is to have both sides of the wings in equal tension
but if one side needs a bit more tension than the other to properly trim the model then that is
what is required. (NOTE:
SOMETIMES
doing this adjustment
OPPOSITE
to the above
instructions corrects the problem! There are several variables involved and it has been
observed that sometimes this process works oppositely. This little mystery is yet to be solved
but we're working on it.)
If this still does not correct the trim problem go to step 4.
Step 4) Swap spars:
Main Spars:
Swap main spars, or swap main spars and
rotate them. Flight test.
Diagonal Spars:
Swap diagonal spars, or swap and rotate. Flight test.
You may want to start with the diagonal spars first since they are simple and quick and if they
correct the trim issue, no need in troubling with the main spars.
If you have a trim problem with your Slow Hawk wing that cannot be corrected by the above
techniques, please contact HobbyTechnik or your HobbyTechnik dealer.
