Kostez
Fred:
Hi Brian,
Weighted mine (made in France of course :mrgreen: ), and fuselage dry weighted at 1.350kg :D
Note that to build the Kostez entirely, only 1kg of resine is used!
But once again, that depend what you want. A 4m aerobatic glider don't need to be that light (and you have lots in this range of sizes, like the Alpina etc), but for a VTPR glider, yeah, no other choice!
I think my second fuselage is 1.5kg dry, but to be honest, at this size, a 2kg fuselage is not the end of the World, especially in our slopes and with the type of wind we have.

Hi Brian/Fred
I weighted my fuselage tonight and it is 3kg. I used a heaver glass cloth than Fred (210g) and I also got extra cloth added to areas for strengh ( nose, tail, thin area of fuselage in front of the fin, and also where the wing tubes will be located. If I can kept the model under 10kg (4.5m wing span) I will be happy.
I could have made it lighter, however, with poor landing areas on most of the slopes we fly off, a lighter model would not last to long with my standard of flying :oops:
Brian:
Hi Fred,
Thank you.
Do you know the wing area ??
I ask because I am working (early stage) on an own design 3m aerobat !!
It is something that I have had in mind for a number of years now and seeing the Kostez brought it back to mind.

Fred:
Hi Brian,
No, no ideas, just it's big! :D
I'll check that tonight, but you can't really compare the Kostez to a 3m WS glider. My 3meters Quark is big, but compared to the Kostez, looks like a hlg :lol:
John, 3Kg seems "normal" weight for this size :D
Brian:
Hi Guy's,
Thank you.
I know it is not really the same.
However I have some experience of 1.5 to 2m aerobats .
I think if I can get the area right (small cord changes at a span make a big difference) for the right weight I can do do something 'new' that will fly 'big' at a size that is reasonable to handle/ carry /launch/transport etc !!.
Wing loading is wing loading !!!
I have had an idea for a fuz for a long time so we will see !.
