I used good ol 30 min epoxy on the FW-190, Tom. Just be sure when cutting to leave more lip than they show. I had a much easier time with the second one just because I left about a 1/4" more lip from the scribe line. Looks better too. I traced the outline onto the wing and cut away the covering, leaving a bit of an overlap, to expose the balsa underneath. 120 grit the plastic insert, woodpecker the balsa and epoxied into place with lots of tape and weight to hold firmly in place forcing the edges down. I'm finished the wing and most of the guts....my 10S Eflite P-160 install is throwing me a bit of a curve ball though. The retracts work well on the bench and keep air pressure too. Surprising after hearing all the bad things about these.
