Yes, battered and bruised but he's OK now I believe...

Just over a month since I lost the first version, and v2 is progressing well.

I'm working on a lot of the smaller parts first, going through each one and correcting design issues that I noted during the initial build, and others that I have spotted on a review of the CAD files. On the control surfaces, I re-positioned the spars to give the correct hinge installation location and added a hinge pin guide tube to make installation of the pin easier.

For all the Airex skins, I have reduced the glass weight down to 0.75oz, and the unsupported glass is now just 2 layers of 3oz + 1 layer of 6oz. For the highly curved inlets, I reduced that down to just 3 layers of 3oz and that saved a significant weight on each part.

Hysol 9642 is being used for all assembly bonds.

Redoing the main gear doors, I made 3 sets in an attempt to get the detail reproduced and to reduce the weight of the parts.

I have made new molds for the speedbrake drag links to ensure that they fit the cutout in the fuselage and speedbrake correctly (there was no gap allowance on the first ones), plus I have worked out how to reproduce domed headed rivets in the mold, rather than just simple flat topped cylinders.

I have also remade the aileron molds to correct the surface detail, going from raised rivets to flush rivets.

I sent off the wing joiner blade spars to be machined out of AL 7075 and they have just arrived.

Great stuff Paul. I bet the second one takes half the time. Keep us posted.
Very liberal with the Hysol! Does most of that squidge out?
