Thanks - that's how we all learn! And now a couple of update shots, firstly underside rear covers quite a bit of filling / sanding needed to get a decent joint between rear of trunking and front edge of engine covers. Don't worry about some rougher seams on the lower / inner joints - these will be hidden by the fuel tank! And now a general shot with most major parts attached but some small areas to be tidied up: One more error in the instructions; the tail fin extensions (H1 & H6) have pins underneath but there are no holes in the upper fuselage, nor instructions to drill holes out BEFORE glueing fuselage together - bet you can't guess how I noticed this omission!! 4 Link to comment Share on other sites More sharing options...
FortyEighter Posted August 13, 2017 Author Share Posted August 13, 2017 Recent efforts have focussed on tidying up seams etc and adding all the "sticky out" bits! Think I'm just about at the final priming stage and then hopefully some authentic colours. So a couple of full airframe shots - realised that I'd put the air scoops in the wrong places on the engine covers, so managed to slice them off and re-position them and a couple of close ups of aerials etc I used the kit pitot but have managed to breake it twice - if it happens again will just get a brass replacement! Also decided not to use my turned brass static dischargers but there's always the Su-27 build coming up soon............... 4 Link to comment Share on other sites More sharing options...
Valkyrie Posted August 13, 2017 Share Posted August 13, 2017 Great detailing. That cockpit looks better each time you look at it 1 Link to comment Share on other sites More sharing options...

I noticed that when I went to fir mine. I found the rear one but not the forward one, and as you say there was nowt in the instructions. The other thing was that the parts were also indicated to fit on the wrong sides in the instructions. This build continues to get better. 2 Link to comment Share on other sites More sharing options...
FortyEighter Posted September 9, 2017 Author Share Posted September 9, 2017 If you're wondering why there's been no activity on this thread for a month, firstly I've been concentrating on two other group builds (one is in the background) and secondly I've hit a problem: As you can see in the photo, there is a nasty sunken area on the nosecone. Having filled the cone with micro lead shot I then put some filler over the inner end (to ensure that if any of the shot came loose it wouldn't rattle around) before gluing the cone to fuselage. Unfortunately there appears to be some chemical reaction going on inside the cone which is melting the plastic from the inside! I've filled the sunken section and smoothed it off twice in the last couple of weeks but the defect has reappeared both times. Guess I need to contemplate cutting the whole nosecone off the model and replacing with a resin casting, unless anyone has any other suggestion - all ideas are very welcome 1 Link to comment Share on other sites More sharing options...
Valkyrie Posted September 11, 2017 Share Posted September 11, 2017 Not sure of any fixes but same thing happened to my Ukrainian 29 build as I stuffed the intakes with filler to help weight it down. It has seemingly stopped warping and I think il hide with an oil leak or battle damage. Link to comment Share on other sites More sharing options...
lasermonkey Posted September 11, 2017 Share Posted September 11, 2017 I suspect that the solvent in the filler isn't able to boil off, as it has nowhere to go. I'd be tempted to drill a small hole or two near where the issue is, which should enable the solvent to evaporate. Cheers, Mark. Link to comment Share on other sites More sharing options...
trickyrich Posted September 11, 2017 Share Posted September 11, 2017 yeah large amounts of filler will do than unfortunately! One of the unfortunate issues with filler also in large quantities it will shrink and crack over time. In this case it has softened the plastic and started to shrink. The best thing for holding nose weights in is CA glue or even plastacine will work. Just give a few days to settle down, you an try drilling a small hole to see if that helps, then you're just have to fill it. It shouldn't be a big job and remember to mask off the area behind the radome, that'll make repainting much easier. Try to use filler for only minor stuff, thin plastic sprue or thin sheet are your best friends for filling all the bigger stuff. Link to comment Share on other sites More sharing options...

Thanks guys for your suggestions, had thought of drilling some holes but.... meanwhile I had found a resin nose in the spares box so decided to go down the cut and replace route. The resin nose needed some fettling to match the fuselage but am now at the fully primed, micromeshed and ready for paint stage (not forgetting to prime all the gear doors so they can be sprayed at the same time: And I also had an excuse to add a decent brass pitot!! 5 Link to comment Share on other sites More sharing options...

jrlx Posted September 17, 2017 Share Posted September 17, 2017 Regarding chemical reactions with lead, I've read that CA tends to react with lead in the long term (years) with similar results of sunken areas in the plastic. It seems the best option is to use miliput to hold the lead in place. Great work on the Mig, by the way! The cockpit detail was specially impressive!

Now I use blu-tack instead to keep the lead shot in place. Link to comment Share on other sites More sharing options...
FortyEighter Posted September 26, 2017 Author Share Posted September 26, 2017 Underside has now been sprayed and she is now sitting on all three legs: Have also attached all the gear doors: Now working on the HUD, so that canopies can be masked and attached before spraying the first coat on the upperside. Progress has been slow as I've concentrated on finishing my VC-10s for the "Made in Britain" build - so not sure if this one will meet the deadline, especially as I don't want to rush the painting and decaling. 3 Link to comment Share on other sites More sharing options...
Valkyrie Posted September 26, 2017 Share Posted September 26, 2017 You've done so well and it's perfect till now, shame to rush her as shel b awesome when done. Been a great build over the piece and I'd certainly still be watching if you don't manage the deadline. I'm struggling too but mine is not near your level... 1 Link to comment Share on other sites More sharing options...
jrlx Posted September 26, 2017 Share Posted September 26, 2017 I agree with Valkyrie: don't rush the build, just keep going with the same level of care and attention till it's finished. I'm not finishing in time as well but as my entry is my first build with a lot of resin detailing, I decided not to rush it.

Jabba Posted September 28, 2017 Share Posted September 28, 2017 As others have already said do not rush this just to beat a deadline. Applying the large badge decals on the upper fuselage does take a lot of concentration. Link to comment Share on other sites More sharing options...

Thanks for your comments, I thought that meeting the deadline was a long shot and have now decided it won't be finished this weekend. Will take my time on painting and decals whilst working on my F-15E (and perhaps a Flanker too). 1 Link to comment Share on other sites More sharing options...
