Hi Geoff

If you have some spare I would like some. I always seem to be looking for lead in my kit to put in peoples planes when I test fly them and I am sure my next model will need some.

Sorry I didn't make Middle Wallop today, but I put the time to good use - it's finished! (except for decals and final set up).

I had managed to convince myself that I was going to need over 3Kg of lead in the nose, so I bought 2Kg (cos I'm tight) and stuck a bolt in before I put the lead shot in each of the nose cheeks, so that I could then tune it by bolting slabs of church roof in.

Image

So then I filled the gap between bulkheads I'd glued in to contain the lead..

Image

Then I filled it up with resin and was about to do the other side....

Image

When I thought it might not be a bad idea to actually check the cg and holy S$%t I only need another 500g! (note to self: should have checked this first so that I could have put less in both sides!!...)

Anyway, this is all it needed to balance on the joiner - if I need to take any out I'll have to start doing that horrible job of chipping out the shot. I reckon I stand no chance of getting the bolt out now either without damaging something. Sigh....

Image

Anyway, I hope you all had a lovely time at Middle Wallop - it was certainly a lovely sunny day here.

Waiting for a nice South Westerly for the maiden now

Can't wait for the next report then Simon with flying shots! :D I did a similar job in getting my cg right but I got hold of some shot blast steel beads, I mixed the required amount into a paste using clear silicon sealant and spread a thin smear silicon in the nose area. Then moulded & pressed the mixture in. If I need to adjust the weight, it can be simply cut out with a Stanley blade.

Anyway good luck with the maiden and if it flys as good as it looks it won't be a problem....

Well done Simon,
Can you twist the Goodwin Vids team to video the maiden for us. with his expert camera work it should be quite something.
Going back to your nose weight,(caviar? :lol:) It is about now that you sit up in bed with a start and remember that you hadn't put the pilot and seat in when you balanced it. :roll:
Have a good maiden mate and if I'm not there as ground crew, give us all a blow by blow account of the day.

regards Terry

I suspect you are right Peter - although the forecast for next Friday looks promising at the moment. Rest assured Terry video will be taken to (hopefully) catch a successful maiden.
It's quite handy balancing on the round wing joiner because I could just bolt a couple of flat supporting strips to the model carrier I knocked up and rest the joiner on them - I always find it pretty difficult balancing third scale and up gliders but this makes it easy. I have bolted a couple of bits of lead to the bolt I put in to make it nose heavy (yes, with the pilot Terry!) as there was a slight inaccuracy in wing tube on this prototype which caused the difficulties in the wing root alignment and meant the leading edge has a slight forward facing angle to it - so I want it nose heavy to compensate.
I normally end up taking mountains of lead out of my gliders whilst trimming them so I expect I will this time too.

Andy S send me some fabulous decals so I put those on this morning...
