Thanks Fred for your answer!

I will retry tomorrow to print the fuselage plan, i will double-check to the scaling on Adobe.

For the spar:
- on RCG they say 3*10 mm spruce spar and 3mm balsa share (vertical grain of course); could be good?
- wing joiner in this case? spring steel (12*2mm) and brass tube(13*3mm)? how long?
- is really needed to have a full-sheeted wings or can I save some weight with it?

Slope Soaring / presentation & some question

« on: May 19, 2013, 16:58:35 PM »

Hi guys! I'm Michele From Trento (Italy), and I love to build my models from myself, especially from wood. I've just began to scratch-build this plane, from the V2 plans.
I've found some problems printing the fuselage plans on a plotter: I print from Adobe Acrobat but I get a completely out of scale plan. No problem instead with the wings plan. I downloaded the V2 plans from there (http://jivaro-models.org/quark_2m/page_quark_2m.htm).

Now a building-question:
I've seen on RC-Groups that someone used a spruce-spar with shear webbing. Honestly I've ever built my spar in this way, instead of CF spar. What's better, in terms of torsion-rigidity and weight?
