It's a dog's life. I think there will be room for her inside the fuselage?

Nice! What ply is that and where from?

It's just waterproof 4mm ply from the builder's merchants. Nothing special as it's meant to be a cheap aircraft! If that was liteply I'd be bankrupt by now surprise

Here is a basic dry build to test former locations are OK for the nose section, alongside the A10 nose :

The formers will of course be hollowed out, apart from F1 which will be solid so I can bolt lead plates to it.

Very nice Andy,

I believe you said earlier that the fuselage will have a join; can I ask how you manage that? I'm almost at the stage of drawing up the AC130, so could be very useful for me.

Cheers

Ade

Hi Ade and thanks!

The load of the weight and flight forces from the tail section are transferred into the ply structure via 15mm aluminium wing joiner tubes.

I did this a similar way on the A10, but there I only used 2. The C17 uses 3 (much more tail area). So the loads are carried by the tubes and the whole thing will be pulled together with wire fence tensioners - again a carry over from what I used on the A10. If you need some pics of how I did that, take a look on the build blog on this site

Thanks Andy; just found the pic of the tensioners; know now what you mean. Many thanks

Cool, I used 3mm from Wickes (rubbish stuff) on the Imp. Which shop was it from? Want to build up a repository of budget large model building supplies

From a local supplier called BPS. I think they have branches around the place.

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!

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!

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!

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?

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 yes

that's still fine - I only feather it in from 1/3 or 1/2 span anyway even on a stumpy model. Good work.

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!

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 laugh The parts needed are minimal in cost (£10 tops), and the majority of the work is in the setup before each cut.
