Foam Habu elevator control modification
Remove this ad - become a site supporter!
Went to set up my foam Habu the other night, found the stock elevator control very stiff and the stock servo just couldn't move it. Although they designed it very compact to fit inside the the vertical fin fairing, the moments are very small which makes the servo really work hard. So, took out the servo, control rods, torque rods and the plastic plates in the elevator.
I had a few HiTec HS-82 servos which I really like. So looked at what I had to work with and how to keep it relatively simple. So, just cut two rectangular hole on either side of the fuselage under the horizontal stab and mounted two series on either side with one hooked up to a Turnigy servo reverser. All the wiring fits inside the vertical fin fairing nicely and the rudder and elevator servos still plug into the stock extensions.
Now, I have a very firm, slop free elevator setup, all is good. The servo wires do extend into the thrust tube area slightly, but tape will hold them smoothly in a slight channel cut into the stab section then go up through the hole the old elevator servo was mounted in.
