Gday Jason
I am going to use square carbon rod for the main spar and then grp rods for secondary transverse spars and then smaller sections back to the trailing edges. I have based this on the method Multiplex uses to stiffen up their foamy hotliner. I think it will be fiddly as all hell however seems to produce a very strong wing without too much weight. I have a mile or so of carbon rod so may substitute some bits for the grp?
I will have a better idea of what I am up for when the mercury EDF turbine arrives and I can start to do a concept layup.
I had a eureka moment last night in regards to my B2 plan which involves extending aft from the straight trailing edge with a balsa/ liteply buildup.
Will blueprint and post when I have this sussed it out. This means I do not have to have to hack off any foam and can largely keep the aerodynamic integrity of the foil.
Cheers
