So I figured I would take my SC down the street and fly a couple packs through her while I wasn't busy at work.Everything went great until the end of the second pack and I was coming around for a landing and a billboard jumped right out in front of me!!!  I was just watching it come around and "THUNK" right into it!!!  No biggie!This will be my first major repair so I have a question....I have Gorilla 5 min. epoxy,hot glue and foam safe CA.....which one should I use for the main fuselage? I might also need to go back to Americas Best and get my contact prescription checked.....Stupid depth perception!   |

Gorilla glue > WHITE! kind.
Use sparingly as it expands.
The others will work also: epoxy is faster and more brittle, hot glue is too fast for a break like that, and frankly I just hate CA. Near as I can tell foam safe CA ONLY glues fingers together and nothing else. Some people seem to use voodoo or something to get it to work.
You've got WAY more damage than you think. Check the motor, gearbox, prop, firewall, servos..... everything. Assume nothing is still OK.
Hits like that can take out the ESC too. The battery box is obviously messed up. May as well do the Popsicle stick reinforcement.
Yeah, depth perception is harder than you expect. I treed mine 2x and was SURE I wasn't within 20 feet of that tree.

Ya, I am going to tear it down here shortly. I had done all the Popsicle reinforcements just have to glue them back in. It was a very hard hit so I am pretty sure I did some damage in the motor/gear box area.

Voodoo or something to get CA to work Lol! I laughed out loud to that one Fly. I've never used it so can't comment. In fact, all I've used so far is parcel tape, clearly no use for that break sadly... Looked like a real beautiful day there too. Wish we had skies like that in Scotland...  |

Be VERY careful to get those sections perfecty aligned when glueing.
It is easy to finish up with a twisted fuselage if you don't get such a major break lined up properly.
Probably one of the reasons flydiver says hotglue is too quick. You need a glue which will afford you the time to get everything just so before it sets.
(Some day, someone will write a scientific paper on the astonishing propensity of inanimate objects - trees, buildings, fences, billboards - to inexplicably launch themselves into the path of RC aircraft.)

My opinion only....invest in some UHU POR ( Also called UHU creative in the US). Fantastic magical foam safe glue I use on depron foamies. You can also try gorilla glue, beacon-tac, copydex..... and, rather than using popsicle sticks, invest in some carbon strip (2mm) - This will make your repaired plane practically bulletproof. Also get some low tack masking tape for holding it all together while it cures...Very useful stuff.
Good luck with it, and hope you're airborne soon.
Chris.

All good suggestions from Renaud and Chris.
Bamboo BBQ skewers are the poor man's carbon. It works well in short lengths, can be split in half if wanted, plus comes in different diameters and lengths making it pretty versatile. I use it a lot reserving the carbon for important applications (but I'm cheap).
The Cub is Z-foam so is relatively immune to 'most' solvents and glues so about anything decent you LIKE to work with is OK. Always pays to test though instead of watching your plane dissolve.
Sometimes I think RC is more about glue and tape than actual flying. At least since I took up combat it sure seems that way. You should see the repairs on my combat plane!

Thanx for all the info guys! I picked up some Gorilla Glue and I actually have a T-28 wing and fuselage that a club member gave me that are pretty much destroyed so I can break a couple pieces and do a couple practice runs before I tackle the actual piece I am working on. I have never used Gorilla glue yet but have done some minor foam repairs on my Trojan with CA.
As far as the motor and gear box? How easily should the shaft spin in my finger tips? I dont seem to be missing any teeth on the plastic gear.....Is that considered the spur gear like with my trucks and cars?
