Wing bolting question!

       Remove this ad - become a site supporter!
I have a Tiger2 that I am getting ready to fly and I am a bit worried about the dowel on the front of the wing securring it, there is one on the front and 2 bolts on the back, I am not worried about the wing ripping off in upright flight because all of the force will be into the fuse but on inverted flight (since i love doing it) should i have any conserns or maybe do something to keep it from ripping out!

I had a tiger that I crashed ealier this year. I was flying inverted and I think the wingbolts actually fell out. I was pushing forward stick and it started diving a bit so I went to full forward stick and nothing. I toasted the plane. Anyway it the dowel held up to all I could throw at it but I would watch the wing bolts if there not nylon. Mine had 6-32 bolts and blindnuts. I wouldn't build it that way myself but I bought it second hand. Anyway I learned my lesson. If

To awnser the question really simply don't worry about that dowel.

I add a short piece of fuel tubing over my wing bolts (when I use steel) between the wing and the saddle, to give me something to compress and keep them from backing out.

Also, The Tiger is notorious for developing aileron flutter, watch for flimsy ailerons, and torque tubes.

HTH, Jim.

bolts coming out...

I had a Cherokee ARf that had steel wing bolts. They kept coming loose so I converted to 10-32 nylon bolts. End of problem. Now if that fog hadn't come down aand ate my plane......

You could slip a short piece of brass tubbing over the wing dowl to give it some extra strength. Don't forget to burry the tubbing about a 1/2 inch or so into the LE of the wing. You would also have to enlarge the whole in the bulkhead where the dowl slipped into.

This is the setup that is on my CG Extra.

Get rid of the dowel and add two new screws at the front of the wing. The dowel will eventually wear and get sloppy any way. How much time, effort and money have you got riding on a piece of wooden dowelling?

I purchased a Thunder Tiger Super Decathelon. The covering was so crappy that after flying it for awhile I decided to recover it. Got it all finished and had a few flights. Got to horking it around one afternoon and the wing popped completely off and the fuse became a powered lawn dart! The wing bolt down plate at the rear had come completely off as clean as can be. On examination, it was discovered that there was very little glue holding the plate on.

I called the dealer but really got no where as expected as I was told I over stressed the wing. On an aerobatic airplane with the required engine? Yeah right! Guess all I gained from the experience was to check the stress glue joints of ANY Arf that I purchase in future. Chalk one up for Jim Mc on Arfs for this one! LOL!
