now that I'm in for repairs
 

What is the best glue too use? I have wood glue. My plan is too try and use the wood glue for a basic hold and then run JB weld epoxy around the seams to strenghten. All the damage is internal in the fuse. I've had great luck with JB Weld on just about everything. It is extremely strong. I think its the best I can do with engine cowl/firewall.
What is the best way to remove the glue that was there before the crash?
The guy that had the plane before crashed it once, there was some fire wall damage. It looks like they used a clear epoxy. Like JB weld only clear.

Thanks

JB Weld is not the best choice for R/C repairs unless you snapped a piece off the engine or other metal component. Too heavy and it does not penetrate the wood so you'd end up using lots.

I use Titebond II for wood to wood. 30 Minute epoxy for firewall or major structural splices (spars & fuselage longerons).

What exactly are you repairing? Foam or plastic needs different cements than balsa. Wood in the tank area is probably already fuel-proofed and so wood glues don't work so weel unless enough bare wood is exposed.

The best investment would be some triangular balsa stock in assorted sizes. Titebond this in beside cracked formers and sheets for repairs.

Charlie,
THanks, It's all wood from the fire wall back to just behind the fuel cell.

Here are some samples of solutions I've used. For a cracked sheet fuselage use TitebondII and pieces of paper grocery bag with the glue wiped on both sides (clean up any slops & spills with water & paper towels. Buy a box of popsicle sticks (like $3 for 500 at a crafts store) and "sister" broken frames with them or pieces of them and epoxy. Coffee filters and thin CA can be used for reenforcing snapped balsa sticks or sheets.

It always pays to think about how best to keep the weight down. Lighter flies better.


I use two kinds of epoxy - 30 minute and finishing resin (like a very thin "two hour" epoxy). I have never been satisfied with the 5 minute epoxy.
