Re: Ordered a 1/2A Skyray kit
That "wreck" is much cleaner than the ones I have experienced. I flew my Junior Ringmaster into the side of my flight box, completely sheared off one wing. I Figure-9'd my Q-Tee from about 50 feet up, stalled it and brought her right down on her nose, shattering the fuselage up to the wing root, ditto with my Minnie Mambo from about 100 feet. I rebuilt them all.

Your Skyray is definitely repairable, and with some gluing the broken pieces back together, then touch up finish as needed, it will be as good as new.


The late Keith Laumer has a chapter (

https://outerzone.co.uk/books/display_chapter.asp?book=4&chapter=8
Keith Laumer wrote:Rebuilding a wreck
The old ship was a dandy, but one day a combination of high wind, a bad launch, and a premature power cutoff brought her in on the concrete runway like a ton of bricks. Pieces flew for fifty feet along the pavement, and when the dust cleared, the rear half of the fuselage was here, part of the front end there, the engine lay twenty feet away minus prop blades, the wing was folded in mid-panel, and the rudder was knocked clean off the elevator. It was a total washout.
At this point the philosophical modeler might sigh regretfully, gather up the big pieces just for the sake of tidying up, salvage the wheels and the engine, and start planning a new model.
The modeler with a few rebuilding tricks up his sleeve would have the same ship back in the air within a couple of hours. In the shattered fragments of a model plane, there is a big investment in your time. Most of this investment can be recovered by careful and systematic salvage.
The first thing to do is examine the remains before the helpful small boys in the area have descended on them and borne away trophies. Often by quick action you can prevent further damage. Perhaps a component is cracked but still hanging together; don't let it get pulled completely apart. Shattered balsa is easy to cement if the fibers are still in place, but it's hard to fit together two pieces that have been pulled completely apart cross-grain. If the ship is engine-powered, mop up spilled fuel and oil in a hurry; you can't cement oil-soaked balsa. And gather up every tiny fragment; you can fit them back together like a jigsaw puzzle, and they'll be stronger than ever.
The rest of Chapter 8 along with the rest of the book make for interesting reading.

Re: Ordered a 1/2A Skyray kit
Ow!
I know how that feels.
CA is super stuff. While it won't be as pretty after a rebuild, it will still provide smiles. Chosing to fix this one will have you in the air quicker than starting over.
Or, take the opportunity to build a more intricate model. I hard-crashed and fixed my Scientific P-40 twice. The third hard-crash just meant I now have the space for a replacement model. I can't keep them all.
Clean all the parts of oil/fuel residue. Think on it for a day or two. Then decide your next move. I'd fix this one to finish the summer. Cruise Outerzone for a scratchbuild replacement to excersize those building skills. This could also be a good time to build a replacement with a built-up wing including your tweeks carried over.

Re: Ordered a 1/2A Skyray kit
Jim, the repair can look as good as new if one wants to put in a little extra effort. This is my Q-Tee, nose was shattered from a Figure-9, direct hit on the nose. Following is a summary of how I approached repair thereof.944_Jim wrote:Ow! I know how that feels. CA is super stuff. While it won't be as pretty after a rebuild, it will still provide smiles.

Fuselage with broken nose parts removed.

Patterns photocopied from plans.

Damaged fuselage front cut away.

Fuselage splicing backer glued in place.

Front fuselage sheet panel and a new cabane strut upright installed.

Rebuilt battery compartment, lightweight synthetic spackling fills imperfections.

Fuselage nose rough sanded.

New wing cabane rest Epoxied in.

Norvel Big Mig .061 with tank mounted in nose.
The repaired plane looks good as new, no one would ever suspect it was wrecked.

Q-Tee, repairs completed.

Re: Ordered a 1/2A Skyray kit
Thanks for all the great rebuild info guys. I guess I'll have to take another look at it and see what needs to be done.

Good for you, TL!

Re: Ordered a 1/2A Skyray kit
Bravo! Good job on the rebuild. I always feel less pressure when flying a rebuild than the pristine "got everything right" version. After the first one, I can fly it like I stole it. I share your happiness seeing the on-deck/in-flight pictures.

Beautiful sky TL. So glad that you put it back together and flew it. I always liked that model.
