I'm glad to hear the CA hinges work on the MT Saphir's. I have nothing against CA hinges per se, my concern was more when used in conjunction with a foam core wing. Often there is a 1/4" TE thickness and large CA hinges will go deeper than this. If one slots past the wood and uses thin CA, it will penetrate the core melting the foam somewhat. Granted, given the amount of CA, it probably doesn't do too much harm.

I've seen thin hinges installed like Will describes in assymmetrical controls. Provided the sheeting is at least 2 mm thick, I've also seen them installed under the sheeting at the core/skin interface. Probably wouldn't work with CA type though given the lower surface is foam so Will's method is better.

I guess I'm just keen on hinge points but they do require a semicircular filing in the control to allow the control to butt up tight against the surface and pivot.

Will, when I get to mine, I plan to build it with e-power hoping it will alleviate the weight and size which is a little large for a 60. I'll bump up the power to ~1700W or more if possible on 6s. I believe John has an electric Saphir II conversion thread here. It appears to fly very well on and off the beach no less!
