foamie hinges
Hi all,
Im new to foamie building and based on the directions of the F22 kit i built, a single strip of scotch tape on one side of the elevons was all that was needed to secure the surface... however while flying it today, when I applied full up elevator, both elevons separated from aircraft, which was actually rather funny, but I was wondering if there is a better way to make these hinges, should there be tape on the bottom too? Thanks in advance.

Better tapes are 3M package sealing tape or DuBro hinge tape. If needed you can add some strips (fore & aft) on the underside with the tape pressed into the beveled joint. (DuBro tape is Blenderm repackaged.)

RE: foamie hinges
What works well on foam is hot glue hinges. Leave a 1/32 to 1/16 gap between the surfaces and run a thin film of hot glue between about 1/2 in. wide and onto the surfaces about a 1/4 in. Works well and you won't break them. Try it on some scrap to see what I mean
