I'll be installing the ailerons on my LT-40 any day now. What is the preferred adhesive for the joining the torque rod to the aileron. Kit manual recommends slow CA, but I've read that 30 minute epoxy is the way to go. What do you all recommend?

TIA

Mike I am not quite sure I understand your question, are you speaking of connecting the push rod to the surface horn that is mounted on your aileron surface?


Randy

Sorry, I probably wasn't too clear. This kit does not use surface mount horns for the ailerons. A single servo mounts on the bottom of wing at the center rib. This servo runs 2 control rods (L & R ). Each control rod is connected to torque rod which is inserted in and adhered to its respective aileron. I'm trying to determine which adhesive is best for the job. While the kit manufacturer suggests CA, several other sources recommend epoxy.

Mike

Ok, yes I thought you had two ailerons since you stated ailerons as plural. 30 min Epoxy will allow you to make any last minute changes if needed and it also has a stronger bond then CA.

I've always used epoxy for the same reasons Blackie/Randy gives. However, now that I think about it, medium CA might be a better bet. The big problem with torque rods is getting the glue where you want it, and nowhere else. Epoxy might push out of the hole and get into places it shouldn't be. Medium CA might be just right, particularly if the hole is exactly the right size for the torque rod.

I would not recommend thin CA, though, since it might harden before you get everything together.

When I did mine, I used the epoxy. I stuck a piece of wax paper between the aileron and wing at the torque rod so it didn't stick together.

Use a little petrolium jelly around the bearing. The epoxy then wont get in there. I also move the torque rods a bit as the epoxy cures just to be sure. I also drill out the holes one size bigger to provide a bed of epoxy for the wire to be glued to. That way the wire doesnt wear directly on the wood and cause it to waller out after a bit. Be sure to ruff up the wire to give it good bonding surface.
