Radicalisation

Near the middle just where they go into the wing boxes! I had a notion replacement might be the repair.

Having flown and rather liking the Radical I thought I would sort out the little crease in the tip of one the tails. Drill a little hole in the bottom skin to poke the superglue applicator through and

Thanks mark r. I will give that a try. Nice bright day today so no shortage of light to reflect!  Here you go Satinet. Pics as requested. 

Next, a bit of Extremism.

Oops...

Just needs the same treatment as the Acacia - now you've practiced it'll be easy(ier)

Use carbon this time - skinny fus

Hi Andy. Don't quite get what you have done there, any chance of a bit of verbage by way explanation please.

I have a feeling you might have misinterpreted my post (not all that clear having re-read it), the cracks are in the joiner on the front where the joiner exits the fuselage / enters the wing box.

I think he has, too. But the tip is one worth following. Cheers, Andy.

New joiner sourced from Martin Weberschock. Thanks to Greg for helping with the transport. Just needs a minor bit of fettling to get the correct fit. It’s close but not quite there. Must sort out the fuselage now!

Started on the Radical nose today. Strip out the gear and have a go at straightening the nose. There is no way to get it back straight because of the form of the break. The nose was only hanging on by half of the remaining side so a short bit of surgery with a nice sharp Swan Morton no 10 and we have a two piece fuselage. Drastic? Well no not really. It was 4/5 of the way to being off anyway. The control runs were bent in the prang and need sorting out. Also I can look at installing a crutch to help with the bending strength of the very skinny fuselage. The fuselage has obviously been repaired here before so it will be an interesting job to repair it better and stronger so that hopefully it doesn’t break there again.

Best of luck with that Graham! I can never make up my mind how best to tackle breaks that are really close to wing seat, so I’ll be interested to see what you come up with. First off, I’d be thinking of an extended servo tray, but there’s probably a ballast tube in the way.

No ballast tube in the fuselage. It all goes in the joiner and wing root.

Not sure what to do with that strange doubler inside the fuselage that doesn’t really fit. It’s the bit on the back of the nose section. It has bits of thin ply added to it as packers to fit the rear of the fuselage.

That looks like an attempt at an internal repair. 

I have never liked putting in internal tubes etc, mainly as it's very hard to make them stick well.

I think I would break that all away before putting the nose back in place, initially with cyano tack. Even if pieces are missing. Remove completely any servo tray and fit a new former that extends back across the break. 

Once it's solid enough to work on , I would then sand it right down removing as much as I could but leaving enough to allow new patches of glass cloth to be added. Possibly in lots of small pieces initially so as to build layers.before adding larger pieces and adding pressure and heat. Hopefully rebuilding into similar number of layers to the original, by replacing old glass with new, and feathering into the old stuff.
