This post is more or less your opion on repairing a motor mount (firewall)on a foamy.
I know how to fix motor mounts on foamies,but i have been having bad luck with them.
The type of motor mount that im talking about is the one's that are just a flat piece of plastic that is attached to the main body from the manufacture.I glue up the mount , which is just a flat piece of plastic with one hole in the center and for other holes for the mounting screws.I have used ca(foam safe), expoxy, and a new type of glue that works great on the rest of the plane called fabric tac).Some of you might call it the firewall.
The thing is i get it all glued up( i do wait 24 hours to make sure glue cures), put on the motor and go flying.I get to about may-be 5 - 6 flights and the motor mount(firewall) comes loose and the motor starts to wigel alot. I do use clamps and such different things to hold it in place till glue cures.
Iwant to know if you guy/gale's have any tips and tricks you do and what kind of glue do u use

Replace the plastic firewall with a piece of plywood.........you can then use servo screws to
mount the motor, and it will stay in place, until you dork it!!!

You could try Gorrila Glue

i don't think Gorilla is the problem...........the plastic motor mount does NOT have enough material to grab.......so the screws keep coming out!!

Let see a Pic if you can . maybe some screws or dowel pins in the right places may help. You can make L shaped brackets to hold it in place.
