Hey guys, just another thread, this time discussing everyone's favourite topic, weight.
This is slightly out of 1/2a teritory, but is still in the 1-1.5cc mark.
My last trial at building a stuntable 1.5cc model ended poorly, or more to the point, portly.
I had what I thought was enough wing area, but the aircraft was too heavy.
When building a profile fuselage, I used the lightest, strongest, straightest stock I could find 3/8" btw, and the only strengthening was a 1/32" ply doubler either side of the fuse back to the wing's mainspar.
Is 3/8" too much? Should I have used 1/4"?
Also, this was a test bed for cutting foam sparless foam wings, so a complete airfoil without leading, trailing edges or top and bottom spars covered in fibreglass cloth and applyed with polycrylic . I now think after having done this that I'd be better off adding some spars and getting rid of the polycrylic in favour of a low temp iron on covering.
Any thoughts on these topics?
