While the Phase Three model is printing:
Will mention some of the changes.
1) Model has been up-sized to 30" Wingspan [76.2cm]
2) Printed on 90lb Index [162.8 gsm]
3) Wheels will now be tires instead of discs
4) Balsa cut for Wing Spars
5) 1/16" [1.6mm] thick balsa will be used for fuselage internal supports
6) Learned how to create a new color in AutoCAD, using it instead of gray to better match the real color of my airplane
7) 1/4" Wide [6.3mm] Rubber Band will be used with double loop
8) 9-1/2"Long [241.3mm] Propeller will be used
The balsa wood wing spars have been cut. Two each 15" Long [381mm] will allow for dihedral. Will glue and clamp together to hold correct dihedral when drying with clothes line clamps.
Wing spar is exact height of highest point of airfoil shape. I plan to insert the wing spar through the fuselage, once properly glued into position with proper dihedral, wing skin envelope will slide over the spar, then tabs inserted into fuselage as normal. Hoping the balsa will maintain the proper airfoil shape without needing any ribs.
Fuselage will have minimal 1/2" Wide [12.7mm] x 1/16" Thick balsa internal supports. Wing spars will penetrate through one of these supports. Supports will be box shaped when done.
Hoping the paper tube will with stand the double 1/4" rubber motor winding, and the tail hopefully will not kiss the nose.
Printing is done!
Quick lunch and then time to cut and build.
