I saw those. I was hoping for scans, maybe some build notes, airfoils, a website.

Awesome sculpting skills V1VrV2! You guys have mentioned twisting the wingtips for a control method... Could you make it a wingeron type control system, but with an extended drive to twist just the tips of the wings?

So showing us the molds mean you will be making more fuse for folks like me...?

Making a test fuselage tomorrow. Had lots of trouble getting the plug out of the molds. Didn't stick, just hard to release due to all the weird shapes involved. The test fuselage will flex unlike the plug which is rigid. Might not be as much an issue.

Use wood hammer gently knock around the weird shape areas before getting the plug out of the molds.

Before you start banging on it with a hammer try using air.

I wish I had the time and resources to learn how to build molds. It's like a hobby within a hobby.

Are you using PVA? Soaking the whole thing in warm water works a treat.

OK guys, first fuselage is built and curing now. Pulling it out tomorrow. Keep your fingers crossed It doesnt stick too bad or its back to square one!

The molds are destroyed. The geometry the fuselage created a couple places where the part was locked in the mold mechanically. The eye sockets and feet were the main culprits. Looks like the molds will have to be re-built into several sections to split the negative areas.

The good news is I saved the fuselage. It is perfectly usable as is and before spending gobs of time making new molds I plan on going ahead with building a prototype.

Feels like I wrestled with a Grizzly bear getting the part out...

Oh man!! So sorry to hear that. All that work... stay on it! You will figure it out.

Can you salvage parts of the mold? Maybe saw off the head and feet area, and re-use them?

Maybe a more flexible silicon mold would work?

Ok. Got some more done on the prototype, the basic structure is done. Deciding right now on how to install the controls and radio gear. No shortage of space in the fuselage so that should not be a problem.

Tip feathers are screwed on with nylon bolts so they can be removed and replaced easily if damaged.
