Thanks, Peter. I'll give that a try. I did a search for 10mm plastic tube on eBay and this stuff came up at about 2 quid/metre. I had thought of trying to get some Serabend from somewhere but I'll see if I can find some silicone tube in my junk drawer.

Hi Geoff try blocking one end of plastic tube filling with sand then block the other end heat with heat gun bend to shape when cool open up and the sand will run out

Hi Geoff, I had the same problem to solve when I built my Hawker Demon. I made the zig-zagged exhaust pipes from balsa sanded round as explained on this plan in the diagram just in front of the fin :

https://outerzone.co.uk/plan_files_06/6269/Hawker_Demon_RCM_757_oz6269.pdf

I probably then sanding-sealed them and covered them in tissue doped on with the sanding sealer.

The same thing could be achieved by laminating 1/16in x3/8in balsa strip, as often used for forming the outlines of wing tips and tail surfaces.

Kind regards

Gordon

Having seen yours, I wish I'd put mine further out. It's a better position both for keeping clear of the stitching and, being wider based for stability. I should have read your build thread more carefully

No building today. Got a load of stuff to organise for a swap meet. I keep building and I need to clear out planes and engines that I'll never use. I hope to get home with an empty car ... that's if I don't buy something myself - but Avice will be with me to keep her tight hold of the family purse strings devil

Can you expand on your first paragraph. "Put mine further out" What further out.?

Thanks Martian and Gordon. Tha's two ideas to try

OT, the plywood hooks that hold the top wing in place at the front of the support platform are shown as near the centre on the DB drawings but they could be placed near the edge of the platform which would, arguably, make them a bit more stable. In practice the wing is very secure when the DB drawing is followed.

I felt the same way as you regarding the plywood hooks built into the top wing mount. In the end I just built it as per plan and never had a moment's bother. The Moth isn't going to - or at least shouldn't - endure violent aerobatics, so in the end I just put my faith in Boddo. If they're corretly done Geoff, the wing struts will lend sufficient stability to the structure as a whole once the top wing is bolted in place. I did drive some small woodscrews into the plywood hooks from the lower side of the plate they're mounted on though Geoff. I'll be doing the same when I get that far with the latest one.......

It's actually all coming flooding back, as the first time I did all this was in 1990 (the model in my header pic)........... The biggest difference this time is the huge improvement in the quality of the kit. I think that was down to Eddie Stocker when he ran DB, although Richard the new owner seems to be keeping up the reputation well enough as well as introducing some new ideas of his own ie: re-kitting the Tinker bipe. That model was a firm favourite of mine 40 years ago, and I still have two new unbuilt Micro Mold Tinker kits to go at! They'll need a few slight mods for electric, although the new version of the Tinker was re-done by Richard as an electric mode

PV: IIRC the latest drawing for the Moth shows wood screws as well as glue holding the the top wing hooks in place. In any case I did that and I'm quite confident the wing will stay in place in normal flight - even violent aerobatics!

Certainly Richard is keeping up the DB quality as did Eddie before him. I'm almost tempted to buy a new Gringo kit as my original one (and its builder!) are featured on the DB web site but as I have limited time I think I'll commit to building sport-scale models for anything other than very quick builds.

You seem to have a few kits in hand!

I have 15 or so kits in my stash Geoff. Like the Tinkers, some go back a decade or four, others are slightly more recent. I have a couple of the old Skyways jobs which don't seem to have made it back into production with Mr Mason, the new owner. The Tinker bipe was always one of my favourites. Easy and simple to build, yet flying it provides plenty of pleasure. An aeromodelling gem if ever there was.

Oh, and I have a little bundle of DB kits too Geoff. All nice relaxing builds for long dark winters.......
