Aileron Servo - Mountain Models MiniFlash Builder Manual

Elevator and Rudder Servo
! Install the rudder and elevator servos into the servo tray.
! Attach the rudder pushrod through the outer hole of a single-horn servo control horn, then install
the control horn to the rudder servo. Do the same with the elevator servo.
We will now attach the pushrods to the rudder and elevator. We will use a piece of 1/32" music wire
bent to an "L". The short end of the L will go into the control horn hole and the long end will be
attached to the pushrod with heat shrink tubing.
! Cut two pieces of heat shrink tubing ¾" long.
! Slide a piece of heat shrink over the back of the rudder pushrod.
! Cut two pieces of 1/32" music wire 2" long. Measure in ¼" and make a 90 degree bend.
! Take one of the music wires and insert the short end in the rudder control horn.
! Slide the other end of the wire into the heat shrink and heat the heat shrink. You will adjust the
length so that the rudder points straight back. Use a drop of thin CA to prevent the pushrods from
slipping in the heat shrink.
! Do the same for the elevator control horn.

Aileron Servo

! Install the aileron servos. Feed the wire lead through the oval hole in the side of the wing and into
the fuselage.
! If you have a computer radio where you can trim the individual aileron servos, you can make the
aileron pushrods out of a single piece of 1/32" music wire. If you don't have a computer radio,
make the pushrods out of two pieces of wire so that they overlap in the middle and are re-joined
with some heat shrink tubing. This way you can adjust the length to trim the ailerons so that they
are level with the wings. Once adjusted, apply a drop of thin CA to the heat shrink to prevent the
wires from slipping.
Motor and Gearbox Assembly
! The stock motor is neutrally timed. You can get more power out of it by timing it. I have a pair of
bent nose pliers that have the tips ground to more of a point. On the endplate of the motor, there
are two holes. I place the pliers in the holes and rotate the plate clockwise as shown in the photo.
Note the position of the red dot in reference to the tab that holds the endplate on. (The dark dot in
this black and white photo.) You may need to unsolder the capacitors on your motor to be able to
rotate the plate far enough. Make sure you solder them back on!
