Status: online 		Just wanted to give an update, here are some pictures of the repaired Extra right before the fist test flight. Dry weight is 26.25lbs, one click of left aileron and one click of down elevator and it would fly hands off the length of the field. I still have a lot of dialing in to do, but so far everything is holding together.

Status: offline 		hey i have a question for you uys my friend has a comp arf extra he crashed he said that its got gear damage which i know is easy to fix but the big damage is about 3 inches behind the taiking edge of the wing on the fuse i guess it crunched it there but he saiys its not fixable, at least not to the point where it woud be safe to fly again. what do you guys think?
i was thinking about trying to fix it but not real experienced with this kind if repair

Too many people believe that once you break a composite airframe it's the end of the plane. Not true at all. When you do patchwork on a comp plane just think about how the patch/repair will carry into the rest of the structure. A long time ago a comp specialist told me to think of a tree and how all the curves come together to make an entire tree. Each part adds to the strength of the other.

If you can''t fix it with a hammer, you have an electrical problem.

Status: online 		John,

That was a really nice job on your repair. A good thread to show people that just because a fiberglass/composite ship goes in the ground, it does NOT automatically go in the trash!

Kevin, as Ed and Surfer Dude have said, it is a common practice to repair composite/glass fuselages. I have found that working with glass one of the BEST properties is that the repair can be done both in a lightweight manner plus there is no loss of strength. Look over John's repair/methods and I think you'll get the idea...Just to give you an idea... I repaired a customer's .60 sized pattern fuselage that had been torn in two pieces..... and when it was finished, not only would you never have known it crashed but you couldn't even find the repair points. It just takes time.

I'd pick up that broken plane, fix it, and then let it get around that you have a new, secret technique... don't tell anyone that you simply read up on the topic..all information carefully hidden in BOOKS..(and computer screens)..LOL...

btw... Ed... things are a POPPIN'!!! Havin' fun again.....

Status: online 		Sorry I haven't looked at this post for a while, thanks for the kind words of encouragement. My friend just dropped off his 2.6 meter extra with some moderate damage after a pancake landing. I think I will start a new thread on the repair process. I am like the challenge of fixing the Comp-Arf's, the only thing I am not looking forward to is replacing the landing gear plates inside the fuse.

I fully agree with you Dan, just because a Comp-Arf goes in doesn't mean that it is lost for good. I have another 3meter Comp-Arf that was involved in a mid-air and lost the entire vertical stab and one half of the horizontal. I haven't got up the strength to tackle it yet, but I have no doubt that it will be just as strong when I am finished as it was when it was new.

Thanks Again,
John

Status: offline 		sticks-RCU--- I took a gear plate out on a 2.6 a year ago on a gopher hole when I landed of the paved strip. It actually is a piece of cake to replace, don't sweat it. If you run into any problems drop me a line.

How did you get the old plate out? Any suggestions are welcome.
