It's a little hard to see the depth of the damage. If it's deep to my unlike I wood first mix some epoxy with some fibreglass mill and fill up the hole. You mite have to use some Automotive masking tape to form the shape. Just let it dry, peal tape, than sand as smooth as possible. Any imperfections can be filled with a light automotive body filler. You will than prime, paint , and spray a clear on the finished product. Any good Automotive paint supplies will be able to match the paint colour. However if you can get the paint code from BVM or some touch up paint that would be even better. The photo damage looks small so if this is the case I would do it with an air brush. If using two pack paint make sure that the rite quantities of hardner and reducer are used. Always where a proper paint mask especially with two pack paints. You will have to blend the spray job with the existing paint. Do not mask the damaged area and just paint that. It will stand out and look horrible. Hard to explain but you have to spray the repair and as you spray over the non damaged wing you slowly back off. You will be spraying a bigger area of the wing to blend it in. You could possible need a light wet sand after before the clear goes on. In saying this it's hard to give advise without seeing the damage with my eye and seeing the spray job. This is just some of the things I had to do for my own repairs. If the hole is not deep all you could is use the body filler. Not deep by my eyes is 1 mm or under. Just my opinion.

That is a very strange way to damage a model. A bit like the Qantas A380 incident.

From the photo it does not look like there is structural damage.. I would suggest just filling with a 2 part auto filler and then priming and painting. The correct yellow colour may be hard to match..

BVM have done a great tutorial on this kind of damage.. http://www.bvmjets.com/tips/Flying%2...%20Repairs.pdf

Justflying has some good ideas.. The only things I would add.. During the repair process, try and keep the "working" area as small as possible as it easy to spread the working area as you sand out the various fillers and primers..

Masking tape is your friend. Use it to limit the area you are sanding.

Good luck

Better yet, fill and sand like suggested. Then cover the leading edge with a strip of chrome film or metallic silver. Many leading edges are finished that way and no one but you will know it was not that way from the start. About a 30 min fix.

Yes..... But that would be cheating.

Actually it is a brilliant idea..

If your not cheating your not trying.
Ask me how I know this works

If you can see the fibers as you have mentioned... Dab a bit of thin CA there. It will wick back into the fiberglass and replace the resin that was shatter in that area. Then do as the others have mentioned. Its not serious at all.. mostly cosmetic.
