Back to work after the Christmas break. I had to work out a way to make the inlets so they were reasonably sculptural and yet fairly easy to make. I had to increase the size of the inlets because of the higher mass flow in my engine. I will make the ears so they are part of the cover and will come off with it. This means I can get to the inside to trim out the opening in the skin. I marked the position with pins so I know where to cut out. The cover will be subject to some forces and I will not rely on the magnet system but have a pull out wire that holds it in place.

Finished the intakes apart from some more sanding. Not filled anything yet and I think I will go for a white fuselage and a light stain on the woodwork. The angle of the retracts looks fine but there is limited ground clearance so I will need wingtip skids and tail skid to protect them from scraping.

I have now filled the balsa sanded it and applied glass and skinning resin. This is a job that I never actually enjoy and always fear that the resin will not set after early experience I had with a poor product. However all went well this time. I skinned it last night and it is not fully cured this morning but will obviously do so. I struggled a bit to get the material to follow all the contours and as a result applied more resin than I should have. Having filled the balsa surface meant that very little resin was absorbed into the surface. I guess I should have had a sponge to hand and mopped up the surplus. Never mind all I need to do is apply a second thin coat and then rub it down when set hard.

I primed the fuselage and then decided to cut the hatch out. I had marked the hatch cut out lines and they were getting a bit faint. Just to make sure they were in the correct place I inserted a number of pins and made sure to follow the holes left when I used the razor saw. I cut the bottom line with a scalpel. I was delighted that the hatch came out perfectly and will need no construction, just opening up the intakes and a bit of sanding and general cleaning up.

I will add an upstand to the engine mounts to secure the hatch from side to side and will have a wire latch.

Nicely done John.I made the same error over doing the resin.Annoying when you have to sand it off.

Cut out the horns from 2.0 mm thick fibreglass sheet and made slots for them into the balsa blocks let in earlier. You can see that separating the elevons will be simple, just the ribs to saw through.

Glued the horns in with epoxy, they are off set to allow for ball links. I use Great Planes nylon links with a screw that goes through the ball, and the horn.

Hopefully tomorrow I will have time to saw the elevons off.

I have sawn off the elevons and flaps without any dramas. Nice and easy with Andres method. I had already glued balsa strips to the edges and I needed no filling pieces in the surfaces themselves but the trailing edges needed some thin balsa
added to get a level surface. This I have now done and cleaned off ready to add a thin ply facing skin. I am doing this as I have to tape the flying surfaces on and it makes it neater and more robust.

The thin ply strip were simply glued and taped on with masking tape onto the flying surfaces while the glue dried.

Great Job!

Hej John,

You are building very good. Everything is clean. I hope I can see her one day flying. If You ever go to Germany with this bird, please inform me. I will be there as a spectator.

Lothar thanks for the kind remarks, all I can see is the mistakes I have made. It is not the standard I have seen of your builds. I have to get it flown before making plans to come to Germany. I have the 6 turbine engine Arado 555 and the Boulton Paul P111 to complete the Large Model rules for 1 hours flying before I can bring either. We just need it to stop raining and the wind to calm down. If all goes well we plan to go to Pampa in Belgium and Porz near Koln this year.

Meanwhile I have some more fun in the workshop....I am just not happy unless I am making something.
