Rebel ailerons

[allsure]

G'day.

I have completed the assembly of my wings and I am setting up the ailerons.

However I have found problems. The left aileron rubs on the rear extension of the wing skin, and the right one misses the skin by about 1/4"

What is the recommended factory clearance between skin and aileron?

How do I alter the clearances? (I really don't want to unpick the skins and re do the hinge mountings)

The trailing edges of the skins have developed some ripples also. Any ideas on fixing that?

Thanks and regards

Hello Ian!

I thought you installed those one lug anchor nuts of mine on the aileron hinges!?!?!??! IF you did, loosen them off and put a shim under the top attach area only. This should drop the hinge line down enough to get the flaperons to quit rubbing the trailing edge. If you don't have the fabric on them yet, you will need a little more room yet. The 1/4 " seems a little excessive. Do both wings have the same amount of "rear extension" or is the right one a little shorter than the left?

G'day Wayne

Yep! I did install your one lug anchor nuts, and what a fine idea the are.

I spent some time just trying to work out the way to fix the gaps, and I found that by putting a 1/8" shim under the top bolt of the hinge bracket, and nothing under the lower bolt hole the gaps are now more acceptable. I assume that using different size shims will not do any harm?

I some how assumed that the same thickness of shim had to go under both the hinge bolts!

I can absolutely recommend Waynes nuts (one lugged variety that is) as a great way to attach the hinges. If I had not fitted these I could not have loosened the hinge bolts to allow adjustment of the shims. The fix then would have been much more difficult, and I probably would have had to unpick the wingskins to get at the nylocks.


I also have bought from Wayne clip nuts, that I will use to attach the fibreglass wingtips and aileron and rudder tips. This idea of Wayne's sure makes it easier to remove and fit the tips. I hope that I never need to take them off, but the clip nuts will make it a cinch to do so. I suggest to all Rebel builders that you do yourself a favour and talk to Wayne about his nuts.


That was an unsolicited testomonial!

G'day

OK I give up!

Just how do I manage to tighten the nits on the aileron hinge bolts?

I have found that the access holes are too small to get a spanner in to the nuts.

Ian, for the outer two, hold the nut with an open end wrench and do the no/no and turn the bolt from the outside. The easiest way with the middle "shared" bolt, is to tighten it when the flaperons are not hooked to the push pull linkage (or together)! That way you can hold one bolt with an open end wrench and at the same time tighten the nut with another open end wrench while rotating the flaperon (through it's full travel) and the wrench as a unit! The big trick is keeping track of where the cotter pin hole is (mark a line on the head to help orient)and to get the pin in requires the use of an offset pair of needlenose pliers (only pin when you are sure it's the final assembly!). Do not use elastic stop nuts on these hinge bolts as I have found used on a few of the Rebels that have come through my shop! If you are having trouble getting the nut/washers in place to start things off, the washer goes in with the needlenose pliers and the nut can be taped to the box end of the wrench and held in front of the bolt, while turning the bolt to get it started.

Follow what Wayne said. I also took the torch to a good wrench and customized
it with a bend to make it work. I also have a couple of 7/16 Inch opened end
(spanner's) around here with the outsides of the jaws ground flat to reach in
some where on the plane.

I bought in my youth the wrench fit in no problem and the 1/4" drive rachet

Wayne is there a reason to put the outer bolts facing in? I installed
mine with the bolt inside and the nut on the outside for easy tourquing and
pinning.

Drew as long as the bolt is there and has a pinned nut on it, that is all
that matters! Your way would certainly make it easier to adjust the "grip"
by adding a washer or two if necessary under the nut!

G'day


Thanks for the responses regarding tightening the aileron bolts. I appreciate your help.

I knew that there had to be a way!

Hi everyone, I'm new on the rebel forum and was wondering if I could get
some education on rigging the ailerons on my rebel. I've got them giving me
pretty close to the same deflection on both sides but it is not near the amount
talked about in the manual. Where they give a measured distance from the
trailing edge I've been using a smart level. I'm getting 7.5 to 8 degs. up and
down (no differential). As much surface that's being moved I'm wondering if
that would be enough? Could someone let me know the deflection they're getting
and if what I'm getting is not enough maybe some input as how I could get more
without starting over on the plane!
Any help on this would be muchly appreciated.
Thanks, Randy

I know this has probably been discussed at length but I just had to ask.
Couldn't find anything in the archives.

I was walking by my uncovered ailerons, and thought to myself - such a small
area to be left uncovered by aluminum. Has anyone skinned the ailerons in
thin aluminum (.20) as opposed to fabric. I know this is done on the Elite.
Will the weight make them unmanageable?
