Default RE: 130 Flaps

I'm back. Whew have been moving Daughter into new apt. and not on line for a while.

Bill the page is 373.


The flap linkage was made using Brass stock from the hobby shop. I bent it into 2 90 degree ends so it would mount on to the threaded rod. The threaded rod was big bird elev horns. Don't remember the brand but they used 4x40 bolts and two nylon plates. The 90 degree on the brass prevents one flap from getting ahead or behind the other. This forces them to stay even. I used 2x56 bolts with lock tite to bolt the brass to the nylon eyelet. I drilled the center of the brass for a 4x40 rod end. The rod end allows the flaps to move linear while the servo moves in a rotating motion. This way there is no binding. This is probably a little heavy but I have never had a flap issue. Minor point is the outer edge of the #2 flap. (1 is closest to the fuse) does not touch the wing. This is due to the wing changing shape right at this point. I have about a 1/8" gap here but it is so minor I left it. I hope you can see from the photo I posted how I set it up. If you would like me to post it again let me know. Also if you want more photos I can take them with a digital and email directly to you if you give me your email address.
