| I got a Hornet CP for Christmas from Dreamhobbies.com this
last Christmas, and was having problems with the tail.
This was partly due to the fact that I assembled the
tail wrong. :-(
Because the tail rotor output shaft was so tight on the
inner races of the bearings, I had the "bright idea"
to put the bearings on the outside of the tail gear box
rather than on the inside.
No matter what I did, the helicopter was unstable in
yaw, and would start turning to the left, even with full
right rudder.
Steve (scmodchips) looked at my tail, and saw that I did
not have enough tail rotor pitch in the leftward direction
(when the rudder is moved all the way to the right).
The problem was that since the bearing was on the outside
of the tail gear box, the tail rotor slider would run up
against that bearing and not give enough left pitch to
the tail rotor blades.
Steve and I then came up with a great idea. (Somewhat in
desperation!)
The goal was to increase the rudder authority to the left.
I was somewhat desperate to find a way to do this short of
tearing apart the whole tail, throwing ruined parts away,
etc. etc.
The way I did this was to drill tiny new holes in the tail
slider front piece about 1.5 mm in from the original holes!
This worked extremely well. (I got a #60 drill bit from
Orchard Hardware Supplies, which is 1.02 mm in diameter,
about the perfect size.) I carefully measured with a
metric ruler, and then used a sharp, pointed wood screw
to start the hole. Then, just drilled that baby.
The helicopter now flies EXTREMELY WELL! I'm so excited
I can't stand it! :-)
