G O O P made me a believer.
Below are some pics of my OS .25 showing where I used GOOP glue to fix the needle assembly arm . I didn't think the stuff would hold but I can pick the engine up by the tip of the needle valve and it holds. When I say pick it up I mean rock the engine from a ling down position to the crank shaft being in an up right position.
So I just wanted to say thanks to the makers and people who have suggested using GOOP glue.

HI Ken,
Goop is a rubberised kind of glue ( akin to silicone). Once cured it's pretty tough and flexible. There are several different types, regular goop, shoe goop, marine goop and probably some others. You can find it at alot of retailers, WallMart, Target, Kmart, Home Depot, Lowes, almost any hardware store and so on. I think JB Weld would have been a better choice for this type of repair though.

Ken I bought my GOOP from an Ace Hardware store. On the tube package it comes in , it says it cures or bonds cement,china,fabric,glass,leather,marble,metal,plastic,PVC/ABS,rubber.tile,vinyl,wood, and more. When I saw this list I was hoping it would do the job and it did with flying colors.
To answer sfsjkid question about heat , it is rated for -40*F and 150*F. It partially cures within 2-10 minutes. I held the needle arm for about 5 minutes before I let it go and it didn't fall off as it did twice before I got it right. 24-72 hours is full cure time. I'm sold on it and will be using it often.

RC-FIEND,
How does it hold up in flight? Does it hold up under the vibration of the engine? I've made repairs to an OS 46 that had the same damage with JB Weld. It fixed the problem, but it didn't last long after I started flying the plane. The vibration caused the joint to fail after just a few flights. So on the last 2 that I've broken I've just broken down and bought a new backplate [:@].

Epoxy and some other glues don't work well with fibre glass. Goop was made for it. Stands up to vibration very well because of its flexibility. From a long time user.

Keep us posted RC-Fiend, if it works that will be good information to know.

It probably will be around a while. I used the 'Shoe Goo' on my tennis shoes back in the mid to late seventies. We got little school support, and I dragged my toe on serves. I could Goo the end of a tennis ball cut to fit the shoe. It would stay on until it wore through the ball rubber. Tough stuff. As a poor college kid, it saved the day (date money I'd have spent on shoes ).
I use it a lot in modeling today, although I have never been able to tell much difference in the different 'types', automotive, plumber's, wood, etc.

RE: G O O P made me a believer.
I had to make the same repair on my Evolution .61 last week. JB Weld didnt work, some kind of supposedly special metal epoxy I got at Lowes didnt work either. I finally just bought a package of nickel plated steel straps made by Dubro (2 bucks, I think), drilled out two of the holes to make them a tad bit larger, drilled a hole in the part of the needle arm that was broken, and bolted it back on. Now it's just as strong as it was to start with, is in the same place, and I wont have to worry about heat or vibration degrading an adhesive bond.

I don't know if it is glow proof, but gas will eventually break it down. There is a gas substitute you can buy at walmart. It is in a red and yellow tube and is sold in the automotive dept. It is not a goop product.
