Default RE: Composite-ARF Integral, kinda build thread

Integral 2 Pushrod set up and Rudder Control Horn setup pictures.

Push rods are made from 1/4" carbon fiber with Titanium ends from Central Hobbies.

They are free floating no supports from servo to elevator. I took 3 rods, wrapped heavy tent thread around all three for about 4 inches and slow CA to form a ======---------- I then added a spreader to form a Y with the ends measuring the distance apart as the control horns. Cut the fuse to match. I have 5 flights on Integral 2. There is NO FLEX and NO VIBRATION noise from the push rod.


I should have taken pictures of the pushrod before I installed it.

I mounted the elevator servo on the Tank tray just behind the tank. Reinforced the tray and added one suport under the tray at the servo. This moved the tank slightly forward of the CG. I am sure it is not enough to matter.

This also saved me the weight of one servo. And in my case 9 oz of lead off the firewall. The push rod ended up weighing the same as the wires leading to the servos that would have been in the stab.

The tail of the airplane floats rather then sag with out the 2.4 oz the servos would have weighed and the plane locks in at a much slower speed.
