I used some Pacer Hinge glue on some Du-bro plastic hinges. And its fine for the 1 st ones you put in. But when you have to do all 4-5 at once you apply glue in hinge slots to install the aileron it sets up fast so work fast it may of been a hot day. ? I do like the easy clean up with water or windex. I may go back to 2 hour epoxy just to give me the proper work time.
