[NSRCA-discussion] Balsa fillets-more old school!

[David Wartel]

Advice from expert scale designer and builder Nick Ziroli: Instead of adding the fillet after the wing and fuselage are built, I make the shape of the fillet areas as part of the fuselage formers themselves.

Richard,

Good news on the wing sheeting.

Your plan to shape the fillets is how I would do it.  Use multiple diameter dowels, larger for the back, smaller for the front.

I would not put too much of a radius into the fillets as that will make them weak and prone to breaking.

Carve the rectangular fillets to a rough triangle before putting them on to save sanding effort and make them more flexible (easier to conform to the wing).

Regards,

Andre
