Guys,

I have a Brison 3.2 powered GP Ultimate using CA hinges with over 200 very hard, high stress flights. When properly installed, CA hinges rarely fail. If you are seeing a bit of balsa on the hinge then the wood never got soaked enough to "harden" properly and is not a CA hinge failure. A Ca hinge failure is usually two things, the hinge literally cracks in several pieces or the outer layer seperates

Two things usually are the cause of this. Not trimming away the covering from around the hinge slot and not drilling a little hole in the slot right in the middle of where the hinge is going to go. Also triming the slot too much will open it wide enough to not get good wood penetration of the thin CA glue

A third set of reasons is either not enough CA was used, the wrong type of CA was used or only one side of the hinge was glued in. In most cases where I have seen CA hinge failure of this type is because medium or thick CA was used where it should always be thin. I've even had students show up with epoxy on the hinges and a quick tug removed the surface in question.

As far as the best setup I found for this plane was Hitec 645's all around, a YS63 turning an APC 13X6. You'll get balastic performance, loads of hovering capabilites and great fuel milage.

Mine has long since been sold. I had one of the first ones to come out. I flew it about 30 flights and sold it to a policeman in Balt. The last I knew he was still flying the snot out of it
