I was repairing an aileron of my lost and found EZglider, my very experienced friend advised me to use white silicone (as used in bathrooms) instead of hot glue or tape, saying it makes a very supple and resistant hinge.

Followed his advice, still have to fly the repaired EZglider or the Windrider Fox (WIP) where I used silicone.

Cheers.

Always test on scrap pieces first to see the results for yourself,It's a lot better than finding out while it's in the air and you will know how strong it is and you will be 100% confident with it.

Good and sound advice, no doubt. I am also sure there is a right and a wrong way to make them with silicone (he lent me some Rubson), as it is the case with tape, hot glue, or pin hinges.

I tend to trust my friend, his help has so much improved my game with gliders!

He has used silicone hinges on some of his foam planes (he also has an EZglider for the days the wind is too gusty to fly his big gliders, he repaired this way after a landing in a wire fence hidden in tall grass).

My friend has been building planes for more than 60 years (also worked as a professional builder of RC planes for scientific projects).

Members of the club give him their wrecked planes when they despair from being able to rebuild them. One or two weeks later, they come back better than new.

He has shown me how bad built were wood ARF from major well known brands (no cheap HK), were wings and fuse had up to one third of unions that were never glued.

He regularly flies 3 to 4 m ws all wood gliders he builds from scratch, varying from vintage to high performance (of his own design). For them, to my surprise he uses the covering film of the wings for hinges.

Here is one of his last builds, she flew perfectly from day one after a good tow.

Truly a knowedgleable guy in scratch building to have around.

Flew my Ezglider with the repaired aileron using white silicone without problem.
It is only one flight, and no indication of the durability of the material, so I will check before any flight.

As jimboflyin very wisely advised, make a mock up aileron and try your technique before using it in flight.

Cheers.

I think it was the first thing that I learned the hard way when I thought I found the next best hinge application.

Silicone hinges used on a 4 m WS glider, DG-300 Elan Acro.
http://www.jivaro-models.org/dg300_reichard/page_dg300.htm

" Mon système d’articulation est fait comme à mon habitude au mastic silicone, ça ne bouge pas dans le temps et c’est costaud. "

If your french is rusted, is says : "My hinges are made with silicone mastic, it doesn't vary with time, and it is very strong".

jimbosflyin's excellent reminder : make a mock up aileron and try your technique before using it in flight.

Cheers.

If people are aware that aquarium glass is bonded with silicon and they need to hold a heck of a lot of weight together then the hinge repair is a light duty job for silicon
I probably won`t be trying this method very soon as all my silicon is in those big builders tubes and it would be a waste to crack open a tube for a few grams of silicon. I will keep an eye out for the small toothpaste sized tubes instead
Wot, no Depron?

I used a small tube of white used for bathroom.
Clean well surfaces to obtain a good adhesion, you can mask with tape to avoid messing.
The hinges are very supple and minimize stress on servo.

I have used Uhu Por in the same way on light models (dust with talc to stop hinges sticking), but wouldn`t trust Por on bigger things

Silicone makes for great hinges, takes some technique tho. Practice on scrap and let it dry overnight.

Finally got around to attaching the rudder back onto my Redaq. EPP hinge tore due to embrittling (real word?) from the paint, worked clear RTV into the hinge area and pinned in place. Should be good for tomorrow.
