RE: question about what glue can be used on a rc?
Yeah they are right, the only thing that might hold up would be a two stage plastic epoxy, which a small tube is like $5-6, even then it could brake again. You can probably just buy a replacement for that much and it would be stronger and undamaged.
And just an fyi a hot glue gun is even less strong then superglue, hot glue is for like craft projects...lol
