Today, I made a start on this. I have decided to start on the fuselage, as I prefer to build wings. One of the things that I haven't yet done is to build a laminated structure, so this was where I decided to start. The two fuselage laminated formers. I bought a roll of proper tracing paper from e-bay just lately, and put it to use on the laminated formers. I found that the plan is not quite right, I traced out the formers, then flipped the tracing over and laid it back over the former. The curves were not symmetrical. F5 was 1/16 out at the worst point, F3A was closer, but I ended up rubbing out one side, then flipping over the tracing paper and tracing the same side so that I had a symmetrical former. I then glued these onto a couple of sheets of 1/4 ply with upholsterers spray adhesive and set to work with the scroll saw and made a couple of jigs. Cutting 16 strips of 1/4 wide 1/32 ply seemed to take a while. The other one is done as well, both now clamped up and sat drying overnight. Cheers Mark

Looking good Geoff. Keep up the good work👍 -

Thank you all for your kind comments. I’m looking forward to getting back flying, once we are all let back out again. I have made a start this afternoon on the Ballerina repair, that I mentioned a while ago, covering off, new wood glued in and now it’s waiting for sanding. Hopefully, tomorrow, I will get the covering on and it will be ready for getting my flying back up to scratch before trying to maiden this. Thank you all for following along and your kind comments along the way. Much respect to the guru (Peter) for his design talent and his helpful words of encouragement along the way. I will try to post up some flying shots here when I hopefully get it flying. Cheers Mark

Looking good Gary. Nice neat snake exits👍 Its all about the orientation of your phone when you take them. Landscape one way, they come out correct, landscape the other, upside down. Cheers Mark

Thanks Gents. Other than a bit of plumbing and the final checking and setting of the linkages, it is now finished. I ended up with the receiver battery (2000mah 5 cell Nimh) under the tank to get it to balance correctly. No ballast necessary 😎 I still need to run the engine in, but that can wait until there is a possibility of flying. Many thanks Peter, your design has given me hours of pleasure building. Cheers Mark

Posted by Nigel R on 29/04/2020 07:08:18: That fin is a thing of beauty. It would never have occurred to me to tackle it like that. You have an extraordinarily neat junction between tail plane and fuselage too. How on earth do you do it? Hi Nigel, Many thanks for your kind comments. I did that with lots of careful use of the iron, changing from cool, to just tack the covering to medium to stick it down, to hot to shrink it where it needed shrinking, being careful not to shrink the junction too much. If I had a pound for the amount of times the temperature got changed while I was doing that I would be a rich man..... Today, I seem to have got a lot done. Starting with gluing all of the surfaces in, I like to use superphatic for this, flooding the hinge slot with it, then after carefully putting a little oil onto just the hinge pins, slotting them home. I also got the other side windows in and the receiver: A few days ago, I bought a vinyl graphic online, I got this put onto the wing today: I then made up the loom for the aileron servos: And I got the aileron loom, servos and linkages installed: That's the wing finished, just a couple of bits now on the fuselage, then check C of G and position the battery, with a bit of luck, it wont need any lead. We will see. Cheers Mark
