Re: [RCSE] Anybody use torque system for spoiler return?
I did about the same for spoiler return springs on my old Craft Air Viking. Similar dimensions, maybe 0.032" wire, it's hard to remember exactly. Similar trial-and-error approach to adjusting the torque spring tension. It worked very well. -Ben Bill Conkling wrote: Yes, I used a small torque spring for spoilers in the wing of my old Aquila.

I put one end into the spoiler, twisted it and spiked into the spar. If the action was too light, more twist, or even a new wire with the ends bent at a different angle. I put the horn for the pull string near the spring location in the spoiler. You may have to make several before you get it right, but you will be pleased when done. It works well, and no more rubber bands to mess with, etc. bcAG4YQ Williamsburg, VA On Fri, 16 Sep 2005, Stan Myers wrote: If so what success/failure did you experience. How did you do it?

Re: [RCSE] Anybody use torque system for spoiler return?
Stan, Back in the late 70's and early 80's a flying buddy and I developed a torque drive system for spoilers. We both had poly ships with plug in wings. A single servo was used in the fuselage to drive the set-up. Since the center panels had dihedral some type of "flex-joint" was required for the drive set-up. We found a coiled spring at the hardware store that fit quite nicely into K & S brass tubing. Using three segments of brass tube one on each end for the receptacles and one in the center for the drive horn this was made up with epoxy. The outer receptacles were filled with some K & S square tubing to drive the rods. The spring provided the flex for the dihedral angle and with a little experimentation of the gap between the tubes enough stiffness to drive the spoilers. Torque rods were made of 1/16" piano wire and the appropriate square tubing to mate with the drive receptacle was soldered to the end. We made drive horns for both the spoiler and drive using brass sheet and wheel collars soldered together. The best way to drive the spoiler was with an articulated arm, forearm and bicep. This gave full 90 degree drive without over driving the servo output providing positive up and positive down. No strings, magnets, or whatever. Still have both ships that I installed the system in and fly one of them for some of our RES events. No issues with it other than the fabrication and materials search. It's great to get to the field, plug the wings on and have the spoilers ready to go.
