Hi folks,

This is a general question regarding the strength and rigidity of a wet layup. Would there be any mechanical difference in the finished item using fewer laminations of a heavier weight glass than more of a lighter weight, i.e. 3 @ 200g as opposed to 2 @ 300g.




Cheers, Marty

Hi guys,

The shell will be semi-monocoque with some internal framework for the undercarriage, motor and transmission. I have considered a core material but not balsa.

I have a friend in Israel who has built an 8 foot long CH53 SkyStallion in carbon with Soric core and has kept the whole structure under 3.5Kg. To go that route I would have to invest in some vacuum kit - which I am prepared to do but for now I'll see what can be achieved with a good wet lay-up.

I've got the two test mouldings in a warm sunroom now to see if they firm up a bit.

Many thanks for the input, I'll report back.




Cheers, Marty
