Wow...great responce Superworm,

Firstly, yes we do have the Hawker Hunter here. Actually is lives in the same terminal area from where I operate the Cessna Caravan in Skydiving operations and yes mate it is a pice of beauty.

Yes you did meantioned some about the turtle deck previously on this thread. My misstake.
Do you think using 1/64" 3 ply is lighter than balsa sheet, or is it just slightly heavier but are offering other benefits compered to that of balsa sheet?
I was thinking to give a try to make either a foam turtle deck and cover with balsa, or as you suggested go for 3 formers and then a skin ontop of that made from either balsa or 1/64" ply. Another way alltogether is to mold a light weight cloth fiberglass turtle deck. Wich construction to chose I dont know but it will most likely be the same for the hatch as chosen for the turtle deck. Saving the aft part of the turtle deck for the fairings is a good idea to save one self from loads of extra work.

Worth restating is that my goals is not to make this plane a 3D plane but to make the best classic aerobat I can. However if the wingload would be low enough there will be an option to have some 3D out of this frame as well. Needless to say this is not too realistic though as this would require a wingload of about 24 oz/sq.ft wich translate to a 10 lbs plane. In all honesty I will be thrilled if I manage to keep this plane at 11 lbs.

Lastly a little present from me to your exciting scale project, a picture showing glassed floor of the 300S.

Regards,

Christian
