CROSS SECTION
The modeler's fix is to apply a 1" long bead of clear
adhesive/sealant (silicone) into the aileron hinge flute,
beginning about 1" inboard of the wing tip end of each aileron.
Wait for the sealant to cure (overnight) and use a hobby knife
to cut it loose from the aileron side of the hinge, leaving it
attached to the inside of the hinge flute and the trailing edge.
This provides enough dampening to stop the flutter, but it will
restrict the downward motion of the aileron at the tip somewhat.

The other fix is borrowed from full-scale aircraft, and is a
simple counterweight technique. Using a piece of 1/16" wire,
bend it as shown and glue (epoxy) a 1/2 ounce fishing weight
to the end as a counterweight. Insert the assembly into the
aileron at the hinge flute about 1" inboard from the wing tip
end, and glue it in place with some 5-minute epoxy. Check to
see it is not rubbing against the bottom of the wing when the
aileron is deflected into the full down position.

Now that you are a PC owner, it may be time to consider converting your future building projects to PC compatibility When
building a new kit, check the plan and determine if it can be converted to use with a PC. In most cases, removing the firewall
and a bulkhead and beefing up the interior of the fuselage with hardwood rails and some triangle balsa stock is all that is
necessary If planned right, the trade-off in weight between removing firewalls and bulkheads and adding a PC is about
even. Even some ARFs on the market can be converted with little trouble. You'll find that the freedom you have with a PC
is well worth a little extra design and building time when it comes to a new member of your fleet, especially since you won't
have to buy a new engine, radio, on/off switch, servos and tank every time you build a new plane!
