This is easy, do a test. Find an old servo with a clean case. Mix up some 5 minute and micro about like mayonnaise. Put about a quarter size blob on the servo case side and squish it to a piece of smooth clean 1/4 plywood and you want to push down so the servo contacts the wing but not forces the wing flat in one area, push down so the epoxy just rolls out all sides about 1/16. If you put too much then you get more roll out. So push down and get the squeeze out and then just hold "light pressure" until it cures. Now about 2 hours later try and pull it out.
Now sand the servo case with 150 grit, clean and repeat the test. The un-sanded servo will hold well for most guys and easily come out in a hard landing or when you want it to. The sanded servo will stay put in a hard landing but still come out when you want it to but will take a little more force. Also add some 8oz glass or carbon to the wing skin to stiffen the servo area if it has not been already done for you before you epoxy in servos.

Based on the comments here there seem to be a huge variance in techniques when going for the glue-in approach. I have only seen two variations where the servo is glued in using a bed of epoxy and micro balloons and is either bare or wrapped in masking tape. But some people are describing servos that pop out of the epoxy easily and others are describing needing to grind the servos out. Can those who have had really good luck with gluing there servos in provide some insights? Thanks for all the information, Corey RCSE-List facilities provided by Model Airplane News.
