    Hey Chris, I am also fiddling with the tail section of my Fury. My solution is to build up with foam and then to sand back to shape. Very few, if any, have mentioned using foam on this forum - am I missing something The foam solution is lightweight and easy to shape whilst also being quite strong. The shaping is being done according to photographs, a model and the mk I eyeball. The Fury FJ3 is very different from the F-86 I have discovered...... and continue to discover Curiously all of the photos I have found fail to detail the fairing closely and accurately from the front and side, and the best images are 'stand off distance'. The one above details the rear section of the fairing quite nicely. But at least the beastie is beginning to look like an aircraft now..... Keep safe and keep well.

    Hi Chris, As I understand it (having read lots and made little and therefore very happy to be corrected by people more knowledgable than me) the glass fibre resin adds no strength and therefore you cannot (must not, should not, don't!!!) alter the structural components of your airframe. The glass fibre resin build has superb ding resistance and if done properly adds little weight - see Chris McG's thread for details of glassing and 'the sauce' which improves finish with little weight gain:. https://www.modelflying.co.uk/forums/postings.asp?th=146393&p=35 I cannot recommend this highly enough, Chris McG has written, and illustrated, an eloquent account of the glassing and finishing process. The glass fibre polyurethane build is 'probably' as good as the resin for ding resistance, and again will not add strength, BUT because the polyurethane is water based it will soak into your balsa and add weight, and will warp structures, UNLESS the balsa is sealed - this IS from personal experience. Capitalised because I really wanted to emphasise it ! I hope that is helpful and look forward to the thoughts and accounts of more experienced builders.

    Here is the canopy light for the Fury, Im guessing the Sabre is similar but I have not looked yet. I was thinking to use a plastic cover from an aspirin or similar pop out pack. Edited By David Sack on 22/10/2020 22:23:26 Edited By David Sack on 22/10/2020 22:24:00

    Many thanks Chris. Love the idea of mixing pva in with the filler, it should improve adhesion enormously. I will post piccys with progress shortly.

    Thanks Steve. I have a bit of work to do! I'll post pics when she looks a little more presentable

    How are the navigation lights working out Anthony ? Are you going to fit a beacon in the rear of the cockpit fairing ? Looks very good indeed. I would certainly like to see your solution for the on off switch !

    Looking very tidy indeed Sir, I think your nelolithic tribesman would be blown away ! Watching with interest as I will need to follow suite. The more pictures the better, and don't worry about the camo paint

    Hey Steve, that looks great ! Did the P38 add much weight. My beastie is well overweight and I'm looking to achieve a good finish without adding too much more !

    This is a bit of a call for help really. Have any of you preped the fuselage with sanding sealer before using epoxy for the glass ?? My idea is to get the surface as smooth as possible with not to much absorption of the resin - due to a raised BMI. There is a lot of info on the web but I have not found anything from 'our team' and our airframe so I'd really appreciate your thoughts. Polyurethane has been mooted as a good way to prep balsa but having had experience with warping I was going to avoid using it until the surface had been sealed with epoxy, and then moving onto McGee's sauce, using the water based polyurethane, to finish. I was going to avoid using P38, Steve McLaren has an impressive looking surface on his Sabre see his thread here: https://www.modelflying.co.uk/forums/postings.asp?th=144587&p=3 It looks great but with my plane already 'obese' I am looking for weight savings. Keep safe and keep well everyone.

    Very tidy indeed Sir ! I shall copy that, with your permission

    Good question Chris .. 'Are sidewinders a therapeutic solution for loss of MOJO?' ......... OH YES ! For the model I used a blob of epoxy resin to provide the 'lens' the first results are encouraging ! And while my model may never look as good as the plane in this pic its darned good fun putting it together and those Sidewinders are REALLY good for my MOJO Regards to both Iris and yourself and of course to Gaston.

    The Fury FJ3 has a deeper nose than the Sabre and the shape is slightly different overall. The shape of the cockpit canopy is also a little less than straightforward Had I realised there were so many differences perhaps I would have stuck to an F86 variant ..................nah ! It was always gonna be Navy Unfortunatley my deeper nose warped ever so slightly and I was not happy with the cockpit. There was no option and so I have had to rebuild it. The challenge of a redesigned front end was undertaken with reference to plans for the FJ3 and using as much of the sabre kit as I could modify to fit. I had used Gorilla glue originally, this time I stuck to cyano. For me the result looks better, meaner ! In this first picture the canopy is resting on the new shape with Captain Grey and the ejector seat in position. Compared with the real thing it doesn't look too far out - but yes, the seat is clearly wrong. The rebuild also gave me an opportunity to redesign the cockpit and with the extra room to move the battery box forward hopefully saving weight at the balancing and trimming stage. The seat was slightly wrong and that has been rebuilt and primed just now waiting for the detail work.The pictures show the 'not quite right' incarnation and the (hopefully) improved version. Captain Grey says he is quite comfortable in the redesigned seat and can't wait to have some seatbelts fitted too ! For some reason he emphasized that ....... several times ? As an aside I have been bothered by the visor on Captain Greys helmet. Fortunately I found one example that looked near identical on a navy Fury pilot, dated 1957, and feel mightily relieved that the dreaded scale police cannot get me for that one (Yes your honour, I will bring the said photgraphic evidence !!!) Thanks for reading the continuing 'Greys Saga' Keep safe everyone.

    For my part Chris I am still feeling sore from finding that my front end had warped. It was not by much but - oh how annoying. So I have rebuilt it and am very happy with the new look. It set me back, but it's all part of the learning curve I guess. In the meantime I have been avidly reading your exploits and the contributions of everyone else, and like you, I'm waiting to see more completed planes take to the air. My model is now being sanded for glassing and I'll be very happy to see her fully covered ready for the hard part to begin. However - If ever I am feeling down with the project I look at my sidewinder and think, 'Oh man - that is going to look so, so mean ' Captain Grey concurs.

    Sorry to hear of your problems but there is always a silver lining ! I was made redundant at 58 and it is the best thing that could have happened to me. I was giving everything to the job, overtime, shifts, covering sick leave and more - and I was going downhill. I left my job, after a little pushing, and was able to take a deep breath. THEN I started my own business and have not looked back. I truely mean it, it was the very best thing that could have happened and now at 64 my business is doing well and I have no intention of stopping, in fact it would be nice to employ someone to do the work lol. My advice therefore is take that deep breath and look for opportunities. See you smiling on the other side.

    Great R.A.N. story, love the humour. I confess I did a double take when I saw a Sabre in navy colours. EVERYONE knows a Sabre would be **** on a carrier and you need Fury's Welcome to the build, its been fun so far and there is a wealth of information in the blogs. So many innovative ways that people have approachd problems. Will you fit the sidewinders as per pics ??? I am hoping we will get more videos of early fliers on the PSSA facebook page (wholly unashamed and delliberate promotion of the fb page plus a hint to the early birds!!!!).

    So many fantastic builds, so many different solutions. Well done to you all, and Pete and Dirk - you have been our 'Pathfinders'. (This is where I should insert a piccy of a Lanc or Mossie !) What the hell - have a link instead: https://masterbombercraig.wordpress.com/bomber-command-structure/no-8-pff-group-bomber-command/pathfinder-force-pff/20-2/ My effort still lacks ....... well quite a lot actually (Captain Grey remains concerned) . But as I do not expect to leave our small locked down Welsh hamlet for some months yet I remain optimistic she will not be a 'Hangar Queen' when we do get to fly.

    Excellent Roody, loved it! With all these learned articles I think we should rename our club the 'Power Scale Soaring University' ?? I have a couple of stories about the Smithsonian which I will endeavour to share with you on another occasion. It has been difficult to find pictures of the mounting and the best images were in a video which I am sure everyone will enjoy - follow the link https://www.youtube.com/watch?v=RCnrGUZZHhM
