Elevator/rudder servos.
All views are with the plane on it's back and from the front.
pic 1:
Installed four HS-645 (133 oz for 6 volts) for the elevator and rudder (two each).
This is the right boom: elevator on the left side and rudder on the right side.
pic 2:
This is the left boom: elevator on the left side and rudder on the right side (mounted horizontally).
With the elevator servos both on the left I get the exact same movement (theoretically!) to each side of the elevator.
At least it is when I move the elevator transmiter stick: no binding.
I did this so no 'reversers' are needed.
I connected up the elevator to the servos because, once I put the vertical stabs on, you can't get to the elevator control rod and horn.
I mounted the left rudder servo horizontally, again, to remove the need for 'reversers'.
I used some 'L' brackets to rotate the servo 90 degrees.
Yellow and Bob Violet sells these.
Pic 3:
Elevator in the full up position.
pic 4:
Elevator in the full down position.
(both of these throws will be dramatically reduced for flying).
pic 5:
I used Debro's 4-40 swivel ball links (#861)
I used 3/4" servo arm distance (center screw to ball link) on the elevator and 7/8" servo arm distance on the rudder.
pic 6:
No time like the present to start routing the wires to where they will actually be located.
The receiver will be in the front of the center fuse.
pic 7:
It's a mess already and I've only done elevator and rudder!
The elevator used one 'Y', two 12" and one 18" extensions (as did the set of rudders).
I used HD twisted extensions from air wild: they have some very good prices on HD twisted wires.
