Slope Soaring / Multiplex Alpina 4mtr

Keith,
Yes, your troubles might only be beginning after the launch.
It's the first few landings that I'd worry about - until you have some feel for it and get the crow set up good.
In strong conditions you have to have it for Mt L lz's.

Hi Keith,
I'd advise a little caution re tomorrow.
Gales forecast.
Very flyable.
However it might be advisable to hold for some nice steady lift so you can trim, set and trim the crow etc.
That is big and fairly heavy - carries a lot of energy.
The crow may need aileron trim and will need a mix to elevator.
Good luck.

Hi Keith,
When using a slow glue ,that cures hard, the more pressure you use the less glue you need and the stiffer the bond and the stiffer the result/wing etc.
With high aspect wings stiffness is important especially if you want to fly it hard and in tough conditions
I think this is you.
You do not want a floppy wing !!!!

Hi Keith,
I'm not suggesting you glass the wing.
I am trying to give you some guidance re gluing pressure for whatever skin is used.You have veneer which does not crush easily so use all the pressure the foam can stand up to.
Also you need to prepare the foam surface, sand with 320/400gt .
Make a 0.6 to 1m long sanding block.

Help I'm a nobody get me out of here !

Hi Keith,
I found a good article in 'that' hints thread on rcGroups on glassing a wing.
There he is using blue foam and with a vacuum and is applying 7psi.
; http://www.favonius.com/soaring/bagging/bagging.htm
We were using 1 to 2 psi on soft foam and soft balsa.
Your wing half is probably 500 in\2 maybe 550.
That is a lot of weight.
You should use as much weight as the foam can stand up to.
We will look at this on Thurs,, also.

When you are happy that you have a bench that is able it is a good idea to get/cut a piece of chip-board or mdf to place on top of the wing to carry this weight and spread the load evenly.
I have seen a 'stack' of concrete blocks on a wing.

Hi,
I assume the same tailplane.
I mean copy the mount, pivot and control mechanism .

Hi Keith,
Yes I would go for all moving ,if removable.
Just do a home made copy of something like the alpina.

Slope Soaring / Mini Toons type close-in aerobatics sloper

Hi Keith, it takes about 40min from Moneymore, and yes it is North and west slopes with another south slope on the back.

As yet I have had no time to do a video, as JP and Andrew work when I am free.
Plus its cold and I am old and suffer alot in the cold weather, too many birthdays lol
Andrew and John are really pleased with their Quarks, if I can get myself out into the shed maybe another Quark will appear soon.
Carbon spares should be here this week.
It was difficult to get spares at 10mm o/d TUBE.

Hi Keith,
Copydex is ok but it is a contact adhesive - instant in other-words.
For a big wing like that I would advise epoxy or perhaps Icema.
Anyway something to allow you time to align everything so as to get a straight wing.
Bent wings do fly, and all too often, but they do not fly good.
I would also advise doing one skin at a time to help with this.

Hi Keith,
Re glass v carbon tows - you can do both or either.
I was just explaining how easy is is to sandwich in some glass when skinning a foam panel.It will add to the stiffness a lot which is good for an aerobat.
Brakes do complicate your build quite a lot.
Crow (easy with RC - not with full size) is very effective and simple to do.

Humour / human slope soarer !!!!!!!

Hi Richard,
That's as mad as it can get.
There were a couple of places in that dive where he was at 6 feet from dead or maybe a little closer than that.

As for getting keyed up on  testosterone . It would do me no good. Mandy says she prefers eating chocolate to having sex. :(

Hey Keith,
You need to check that out.
I've seen that 'Confessions of a post mistress' and they eat chocolate alright  :mrgreen:

Slope Soaring / Kostez
« on: November 10, 2011, 13:10:54 PM »
Hi Fred,
It is as you said transport- carrying up the slope if it is a long walk etc.
Yes I saw the vid,, of the launches.
The wind was not too strong.
I find in strong winds the 4m+ models are a handful to launch while on your own.
I am going for a 3m experiment.
F3A on the slope !!
