Nigel, thanks for the photos, I could have taken some more wood out of the back to round it off even more I guess, there is probably enough thickness in the wood there. The tailplane is sheared on the centre section at ribs 1 for support. I will be covering in solartex so hopefully it will cover ok. Time will tell.
The plan does not show in detail the fairings for fin and tailplane so this is my interpretation using soft balsa, the rear block was recessed to accept the fin post.Triangular balsa was also added at the base of the fin to increase the gluing area. This is the completed assembly, minus fin, dry fitted.
Whilst working on the canopy I noticed that the front lower cross-brace obscures the access to the front of the fuz. This was cut out and replaced lower to allow a 1000mah battery to be placed in the nose as forward as possible.
Just had an email from VMC to say they are redrawing the canopy and making a new plug, new canopies will be available soon.
And now to the canopy, I was forewarned by VMC that they had reports saying the canopy does not fit. So after making the canopy frame I then carefully cut the moulding as close as possible to the edge to leave as much material as possible. Offering up the canopy to the frame it is possible to get it to fit, JUST. However the rear of the moulding has some distortion formed during the moulding process but it is useable. For anyone else building this kit DO NOT CUT THE CANOPY MOULDING ON THE MARKED LINES, if you do it will not fit. I have emailed VMC with this information so it can be rectified when they update the kit.
Canopy framework in position, the rear former F3 had to be remade approx 3mm larger all round to cater for the original problem with F4/5 being undersize at the wing intersection. The canopy transparency will stretch to fit once this is all dry. Some adjustment was also needed at F2 to fit the profile, however, the supplied former could be used. Next step will be to trim and (trial) fit canopy transparency once all is dry I can then see how much the original F4/5 will need to be built up on the top edge.
|Thread: Su-25 Frogfoot for slope|
This is a very semi scale model built over 30 years ago and was adapted from the Pavel Bosak plan for a 40 powered model that appeared in one of the mags at the time. It's not got the detail that most PSS models have these days but it does fly well. The wing is a thindown version as on the plan cut from foam and covered in balsa, blue foam was employed for the engine ducts. I have recently recovered the airframe in glass cloth and paint applied by airbrush. I have been pleased to get this old beast back in the air. I think the thing is you can achieve something that looks the part in the air, may not be a Concors winner but will give a good account of itself on the hill in a good blow. For info I have created an album with some more flying shots. Good luck with your own design and I will follow with interest.

Well that's the mainplane almost complete, all the major work done now to move onto wing attachment and then once that is done I'll move onto finishing the fuz and tail assemblies. Quite pleased how it has come out so far and now looking forward to swifter progress.
In the end these panels came together nicely now need to move back to the centre panel and complete that.
Wiring added for airleron and spoilers with Multiplex connector at wing join. Sheeting commenced with trailing edge, 3/32" washout added at tip tapering to Airleron root. Some builders have reported tendency to drop a wing if slowed up so washout added as an attempt to counter this. Time will tell.
Thank you for the kind words, indeed I always admired the classic lines of this model and when looking to build Lockdown 4!! thought it was about time. It was originally intended to be a winter project but with time on my hands.... The build is progressing slowly, compounded by a few head scratching issues, but will be completed before the autumn. Photos will be added to the album as I go along.
Album added, KK Elmira build Vintage Model Co.
Thanks for the photos, makes it clear how the original kit worked. I guess the two 10 gauge wire are little more than incidence pegs and the mail flight loads are carried by the spruce insert. Shows it's free flight heritage.
When I get time I'll create an album on here to show construction progress.
Thanks Piers, normally I would just go down to my nearest model shop and go through their stock of K&S parts but difficult because of the current pandemic. I've never bought so much on line in the past months but sometimes you need to just go and look!
I had come up with the same solution, 5mm carbon rod slides in nicely to the 8swg brass tube supplied so I'd probably use that. Interesting you mention the spruce joiner, this isn't supplied in my kit and I plan to replace with another carbon rod between the spars to take the bending loads on the spar. I have also incorporated ailerons having heard of the turning problems and top surface spoilers to help control landing accuracy like on my old 100s models.
I am working with VM to resolve this and other problems with the kit and plan, it was a kit they acquired from another producer and they wish to update the drawing and get it right.
Thanks for your input.
Done that and they have been trying to sort it out with their suppliers, the problem seams to be tubing is now manufactured in millimetres diameter, and the 10 swg wire I suspect is the problem. They can find a fit at 12 gauge but this would not be optimum for the bending moments at the wing join. I and working with VM to come up with a solution but thought I would through this out there to see if anyone else had come up against the same problem.
I have come up against a problem with the Vintage Models kit of the KK Elmira in that the wire supplied for the wing join is 10 SWG (3.25mm) but the tubing in which it is intended to fit is 8 SWG, not a snug fit!
A route around in my spares box produced some 4mm ally tubing that will take the 10 gauge wire with a little persuasion. However I do not have enough for the job so ordered some more from a local supplier (ATM4), on receiving the new stock I found the wall thickness was greater and the 10 gauge wire could not be persuaded to fit.
Has anyone out there had this problem and could share their solution please.
|Thread: Canberra B(I)8 from AB B2 Plan|
Today is a red letter day for me as I finally got my cranberry in the air. Flew straight and level out of the hand with no necessary trim changes, brilliant. Ok, I know I'm starting this blog from the wrong end but I wanted to share a successful outcome a quite a lot of work. I think you will agree she looks the business. The model is built from the Andy Blackburn plan and SARIK wood pack. The noticeable difference being the fighter style canopy of the B(I)8 a mark that has always been my favorite since seeing these aircraft in Germany when I was a teenager. If there is interest I'll gladly share my build progress although I have uploaded an Album which may be of interest.
Thank you to Andy for making this model possible.

Love the Oblix Mike, takes me back awhile. Looking forward to following your progress. Paul.
Mike, apologies for jumping on your build blog but thought you might like to see a photo of the completed paint job. The comments by Andy B regarding the durability of a doped surface are spot on, the surface is easy to mark when handling in the workshop but I am pleased with the finish considering there were a number of firsts for me during the process. I would recommend going the glass cloth route. Decals are from Pyramid Models with the aircraft codes produced by a club member on his vinyl cutter, I still have to make the 3 Sqdn crest for the tail and am going to try and make a water slide transfer (another first!) Hope this spurs you on with your build. Paul
