R/C model problem

I took the covering off my i/c powered biplane and discovered fuel residue had leached in under the fabric and soaked into the balsa.
Does anyone out there have any good ideas for fixing this so I can recover it?

I fly both and I enjoy both 😀

I have a .25 Colibri trainer, a large and fast .61 low-wing, a .90 Top-Flite Corsair (3 cylinder radial but plane is not finished yet) and I have a Speed 400 Corsair.

Many planes, almost no time to fly with them 😀

I also fly real Gliders, so it’s a bit difficult to find time to take the models out 😉

Thanks Steve.
It was a bit awkward where all the mess was because of cabane struts but I managed to fix it. I’ve since crashed it another two times and yet to get it back in the air. Not bad piloting I hasten to add, just wind and bad luck on take off both times. My other plane flies beautifully!

The best way of dealing with fuel soaked balsa that I have found is to iron the wood at a high temperature, using brown wrapping paper between the iron and the wood. The paper soaks up an amazing amount of oil. Just keep moving to a fresh piece of paper once that is oil soaked.

After as much of the oil is removed as possible, paint the area with Clearcoat ( by Solarfilm ), let dry, give it a light sand, and then recover.

Ah, yeah that would make it difficult. You can usually fly year round here. Some days are windier than others, but the weather usually is nice.

Bet you get better flying weather out there than I do here.
Its windy a lot of the time, so I have to take the chance when I can-not often enough, hence the long period of training.

I haven’t flown since about ‘04; I’ve got some airworthy planes, just no time.

Started flying with my father in about year 2000, he’d flown RC for several years, and I decided I wanted to get involved. Soloed when I was about 14 years old and flew for few years after that. We had a few planes that we had built from kits. One PT-60 (large .60 size trainer), a PT-40 (.40 sized trainer modified with a mid location wing and made to be a tail dragger). And a little plane called a Sunday-a built from a kit we picked up in Japan. It fit a .25 size motor. And it was the plane I learned to fly on. My father and I would free formation fly mostly, with some free dog fighting mixed in. Did that for several years at a RC club located on the NASA complex here in Houston where we live. I need to get back into it.

‘Bout 5 years or thereabouts.
Just got my Bronze recently.It was one of those silly accidents-just on the take off run a crosswind gust caught it and flipped the wing up. Didnt have enough speed to correct properly and over it went. Broke the cabane struts. Theyre not very substantial and although built carefully to plan, I dont think much of the method of fixing them to the cabane baseplate. Think it needs pinning but theres not a lot of room for it. Back to the workshop to do some more work on it. Shame because its a lovely scale model of G-EBXU and really looks the part in blue and silver.
Still got my Kamco Kavaleirs to play with so not a major problem, just a bit of a pain after all the time Ive spent on it. Got photos but the file sizes are too large and I dont have any fancy photo editing software to reduce the file sizes. So, what about yourself then?

Ouch, when that happens, it can be silly. Out of curiosity, how long have you been flying?

Thanks Cracker.
I managed to sort it out with a liberal coat of Flair grey fuelproof paint, re-covered, rebuilt,………piled it into the ground again yesterday.
It is a silly hobby.

I never had any problems with fuel soaked balsa. And I had alot of it. I rinsed the area with warm soapy water and let it dry. Then took a standard spray paint primer, krylon or the like, and coated the area. Keeps fuel from soaking into it too much in the future.
