Hi i got a ripmax harmony twin and the recomended glue for fitting the nose cone is thick cyano. I dont have any of this and desperatly want to fly it this weekend otherwise i might not get the chance for a long time again. So my question is will any two part epoxy secure it in place?

Expoxy should hold, if its plastic to wood then scuff the plastic a bit. Epoxy does not bond that well to very smooth surfaces.
