A bit of a first for me - asking a construction question!
I'm putting my CMP Discus together, and have met a minor hitch, sort of.
The destructions call for the rudder to be hinged by the supplied 'hairy mylar' discs, and direct that epoxy be used to stick them.
Now, I've never used these things before, so is epoxy best, or would thin cyano wick into the tight slots better?
Logic says cyano.
Over to you!

I totally agree with Andy, cyano is the stuff to use with furry hinges.
As of yet I have never had one fail..........god help me now!

|Cyano it will be. I'll have to nip out and get a tube tomorrow, as the one I have has gone all crunchy!|

Tube? Which type are you planning to use?
I always use the very thin type so that it "wicks" in by capillary action...I've only seen it in bottles but you may have a different source/terminology?

hinges---after a lifetime of modelling i made my first silicone hinge two weeks ago--after watching one of my friends glider pull high G stuff with them in it---i decided to give it a go......dead easy-no fiddling on with mylar/cyno ect and really strong(amazed) and no gap..............

I used Evo-stick hinges on my MiniBongo, twelve months on they're still holding together despite some rough treatment.
Cyano tubes - sounds like Eric is off to Poundsavers, I really rate their cyano, the stuff in tubes seems a little thicker than their bottles, either way £1 for 10 2gm tubes or 5(?) 10g bottles is good value. It's holding all the hinges in my Enya 60 powered Katana 46 with no problem.

Flexible hinges- cyano.
Robart hinges- epoxy.
I tend to use Robarts for almost everything now. I'm not exactly sure why, as they are fiddly to apply, more expensive, and the others have never let me down. I just like them.

I'm with you on this one Andy although I use a proprietary hinge glue that has a very fine nozzle.
