Interesting stuff, but what a pity you've placed in someone's personal build blog for an Italian Sabre.

Perhaps an email direct to the magazine editor might have been more relevant...

I agree, what an utterly pointless post and way to ruin someone's blog.

" I am unable to let this matter pass without comment"..........................you should have, it's petty.

Maybe an admin can come along and delete the comment?

Andy - yup, magnets should suffice. I can always 3D print some tanks if anyone was interested? I know shaping balsa into a circular manner can be quite hard from experience!

Look forward to the woodwork starting yes

Phil has just reminded me that some of the mass-build A4's have R/C droppable tanks (Messrs Hey & Barlow IIRC?)

They are jettisoned before landing so leaving a clean wing to land on. That could be a option....

 

Et voila: The Hey Skyhawk with tanks: Hey Skyhawk

The tanks on the Skyhawk look massive, it's a very nice looking aircraft.

I'm not sure about having RC tanks, would that mean you would have to drop them before a landing. Knowing me I'd forget and rip the mechanism off or something.

How did the mechanism work in the skyhawk?

I've just looked at the drop-tanks, the shape is rounded bottom, flatter top making the front look like a bill with some anhedral on the rear fins. See on this link Andy F86 drop-tanks

To be fair, I'd look for a decent walk-around online that shows the section. I wouldn't trust a plastic kit as far as I could chuck it.

Thanks Mark, Awesome Pics Andy..

Slightly off topic but my mind was wandering and I thought about what happens to the tanks after being dropped, you may well of seen this before but check this link out, Amazing.

Oddly enough I'd just seen that on my Facebook feed just recently. Very clever!

The good lady wife took those piccies, she can steer it well when she wants to.

Great drop pictures Shona. Andy (Meade) does diecast make a difference? To the accuracy that is. Diecast is heavier how far can you throw themlaugh.

Probably just as bad Mark, if not then worse (yes I did see your Youtube cockpit video!)

The problem is, all of the little models are drawn up as artists impressions, or how a CAD monkey might perceive the full size. Can't beat getting up to the real thing, or good photos / videos of someone else doing so. There must be a preserved Sabre in the UK for a group visit?

There's one at Midland Air Museum, just up the road from here - where we went before as a group.

I had my first proper look at the plan tonight....

This is going to be a challenge for me!

Andy,

Take it slow when building and ask lots of questions. There are plenty of Sabres being built for this event, with lots of them hopefully being documented in the various build blogs.

I would hazard a guess that you will probably get more than one answer on how to complete something if you ask a question! laugh

Martin.

Here we go, I've made a start on my Sabre build. I haven't done a lot of building so any critique is welcome. I started off looking through some of the previous mass builds. Picked up a lot of tips.

I started off by making a simple bench with a 25mm mdf top and a piece of plaster board. I committed a crime and cut the plan up to make it easier to handle.

So started with the wing jig, used some triangle blocks to square it up and pinned it to the plan, only problem its its been on off the plan about three times now. I tried to mark all the ribs etc on the wing skins whist on the wing jig. I found this very difficult and for me it was easier to take it off the jig and mark all the lines on the plan. I also trimmed the skin whist flat which also helped. The skin sat in the jig over night to take the shape, don't know if this helped much.

Next job was to glue down the main spar, weighted it down and left overnight. The next day I put the jig back on the building board and pinned the wing skin and spar onto the jig.

I now started the dry fitting of the ribs, I noticed a difference between the size of the main spar on the wood list to the one on the plan, It actually turned out to be a perfect fit at 1/8 x 1/4 as on the plan, it looked too small at first glance but it wasn't.

Next was to glue all ribs in place and add the top spar, I got as far as fitting the false trailing edge.

Now the false leading edge gets bigger towards the root so I assume I just use an over sized piece of 1/8 balsa and shape it when doing the main leading edge??? Just read this back that wont work, need to trim it before the top sheet.

I'm going to add my pictures now, below thanks for reading my blog.

I have one suggestion, could somebody create a thread with a list of the gotchas and errors as they are found to make it easier for noobs like me.

Andy
