Andy Meade Posted February 15, 2016 Author Share Posted February 15, 2016 From a local supplier called BPS. I think they have branches around the place. Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted February 15, 2016 Share Posted February 15, 2016 Looking good Andy - as usual - fast progress on the band saw!! Impressive. Good size for this sort of model!! Apols for off topic, but I have to ask - what's going on in the A-10 cockpit?? - looks like an Ibiza foam party! Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted February 15, 2016 Author Share Posted February 15, 2016 Yeah it does look odd! Thin foam inside to stop the pilot head butting the inside of the cockpit during transport and storage. His helmet has already marked the plastic unfortunately!

Andy Meade Posted February 29, 2016 Author Share Posted February 29, 2016 A bit of progress, but not as quick as I was hoping yet. Time is limited with a bathroom rebuild going on, and 7 PSS builds in various states all vying for attention. So, The Good Lady Wife helped me cut these on Sunday : 3.4m metres of cores. I have also some done some weight estimations using CAD and Excel - before anything is veneered, glassed, glued or painted, she should be at 25lb. Not too bad I think. Onwards!

Phil Cooke Posted February 29, 2016 Share Posted February 29, 2016 Very nice Andy and Shona. Good team work! With you cutting the panels in two have you still managed to include some washout in the tips? Does that play into the outer half only then?

Andy Meade Posted February 29, 2016 Author Share Posted February 29, 2016 Yup - my tiny brain couldn't cope with the trig to get it across the span, though I could have done it in CAD I guess. So yes - outer panels only, 3 degrees Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted February 29, 2016 Share Posted February 29, 2016 that's still fine - I only feather it in from 1/3 or 1/2 span anyway even on a stumpy model. Good work. Quote Link to comment Share on other sites More sharing options...
Steve Houghton Posted February 29, 2016 Share Posted February 29, 2016 I think we all need foam cutting lessons from Team Meade, which obviously depends on great marital bliss and trust! Great set of cores, Andy. However, I think you should plan for a big model next time; never mind these 1/15 scale tiddlers! Quote Link to comment Share on other sites More sharing options...
Phil Cooke Posted February 29, 2016 Share Posted February 29, 2016 'Core, marital values' Steve... I'll get me coat. Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted February 29, 2016 Author Share Posted February 29, 2016 lol you two! Marital bliss?! What is this strange thing you talk of? I'm no expert, but always willing for fellow modellers (and their spouses!) to come over for a wing cutting session. Dinner / BBQ thrown in too, if you are a PSS'er The parts needed are minimal in cost (£10 tops), and the majority of the work is in the setup before each cut.

Olly P Posted February 29, 2016 Share Posted February 29, 2016 Andy - you mention 3D printing some of the parts - is this a machine you have at home or one you have access to elsewhere? I'm looking at investing in a printer when/if my bonus comes through this year, any suggestions around the £400 mark? Olly Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted February 29, 2016 Author Share Posted February 29, 2016 Hi Olly, Yes I have my own at home, a 3DDP Up Plus. Here is the version 2, which is quite a good printer, but rather pricey. I got mine 2nd hand for a lot less then half of that price! I'd heartily recommend a Prusa i3 from a store in the UK. There are lots of people using them, and support for any problem can be dealt with in the UK. I use SolidWorks in my day job (honestly it's still lunch time...probably) and have a version at home too. I've used it for the best part of 12 years now, so get on pretty well. I know a few people that use Sketchup to great success, but they struggle to do things that are just a few clicks away on higher end software. They can be a source of income too! Mine has paid for itself already, as I design and sell items through eBay for aeromodelling with some success. Quote Link to comment Share on other sites More sharing options...
Olly P Posted February 29, 2016 Share Posted February 29, 2016 Andy - I've used a variety of CAD programs, and love Solidworks, but can't afford the pricetag! Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted March 8, 2016 Author Share Posted March 8, 2016 A little update today for a few bits an pieces I got done at the weekend. Here is a wiring diagram, so I know where the splits are; know how many connectors I need; and how much servo wire I require. Nothing too complicated, but Engineers like making lists and diagrams Next up, the fin has been cut in 2 positions, and full length 40mm wide lite ply spars inserted. There is a lot of tailplane on top of this to take care of, so things need to be stiff. Gorilla glued together, and taped. On the right you can just see some freshly lightened formers from the tail section. I think I drilled over 80 holes through the formers at the weekend on the pillar drill, all in the name of lightness. Here is the main-spar former, F7. I have cut a 'ole out of it, but reinforced it around where the main-spar box will run through and key into the fuselage. Some wibbly-wobbly cutting there, but who cares? It's deep in the fus . Onwards! Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted March 9, 2016 Author Share Posted March 9, 2016 Another day another update I have veneered the fin and tailplane now. I am starting the marking up of elevators and servo positions, ready to start cutting through the skins. You can see a standard size servo holder on the one half for scale... BIG! And here is the fin-top - an all lite-ply structure that the tailplane halves will be mounted in. This then bolts through onto the fin, and allows me to change the incidence angle if need be. Holes for servo wires tonight, plus boxing in servo holes. With a bit of luck I'll get the halves joined too. Toodle pip! Quote Link to comment Share on other sites More sharing options...

Andy Meade Posted March 9, 2016 Author Share Posted March 9, 2016 Thanks boss-man! Yeah the fire has really been lit for me on this one, which is a shame as I have many other projects a lot closer to completion. I try and do a bit on them all, with the C17 being the main "thrust", as I find that's the best way - no matter how little, every tiny bit you can do on any of it will always help in the long run.

David Gilder Posted March 9, 2016 Share Posted March 9, 2016 Wow Wow Wow!!! Looking very fast Andy.. Cant wait to start on mine after the A4 and AN72!! Out of curiosity, What is the span for each tailplane half? Its going to be great having a formation flight whilst getting buzzed by Phil's A10.... as I expect mine will be built around the same time as the A10 being finished!!!!!!!!! hee hee!!!!

Andy Meade Posted March 9, 2016 Author Share Posted March 9, 2016 Hey Dave - span is 1460mm across the tail, before the tips are added Quote Link to comment Share on other sites More sharing options...
Harry Twist Posted March 9, 2016 Share Posted March 9, 2016 Lovely work Andy - project coming on at a rapid rate now! That's a seriously big main spar former! Regards H Quote Link to comment Share on other sites More sharing options...
Clive Jones 4 Posted March 9, 2016 Share Posted March 9, 2016 1460 Across the TAIL??? We're gonna need a bigger hill! Clive. Quote Link to comment Share on other sites More sharing options...
Andy Meade Posted March 10, 2016 Author Share Posted March 10, 2016 Hi Harry - Yup need to make she's structurally sound! There's a lot of weight being supported here when she's at rest, and the "bump" load when she lands can be quite high, so I can't have any of this buckling. Have you gotten out with the Horten yet? Hey Clive - yes a bit big! A bigger span in the tail than my last 3 builds' wings! Edited By Andy Meade on 10/03/2016 09:06:17 Quote Link to comment Share on other sites More sharing options...
Harry Twist Posted March 10, 2016 Share Posted March 10, 2016 Hi Andy, Ref Horten - not flown yet - still in her onesie in the hangar! Finishing my B&V and trying to clear the decks to start the A4. I am also partway through another correx build ....so a couple of jobs on the go at the moment. Cracking work on the C17 -have you used any special ply for the formers? If I lose weight and squeeze in a bit, maybe I could slip into the C17 cockpit on launch! Regards H Quote Link to comment Share on other sites More sharing options...
