cap one end of the carbon tube. After
adding lead shot inside the carbon tube
and confirming the weight on a scale, I
added CA inside of the tube to firmly
secure all of the lead shot and capped
the other end of the tube. I weighed
the complete assembly and made an
additional unit so I had two weighted
tubes per aileron.
The weights were secured by
inserting epoxy and milled fiber inside
two holes that were made at each
wingtip of the hollow composite
aileron. I counterbalanced and pressed
the tubes into position. This was done
for both ailerons, and I added 50 grams
per aileron instead, with great results:
a tight linkage setup with a decreased
workload for the servo!
I have discussed a few solutions for
preventing flutter. Ensuring that slop
isn’t in the hinge line and the servo
linkage, and fully or partially balancing
all control surfaces, will pay off when it
comes time to take to the skies.
If flutter is present in flight,
immediately throttle down and
land the aircraft to prevent a crash.
Remember, seek the advice of a fellow
expert pilot or feel free to write me
Until next time, fly hard!
