Apogee Heli-Roc Build Part 2 Rotors and Fins

After separating the balsa from the die-cut sheets, alike pieces are stacked and sanded to the same size.

I hadn't seen die-cut balsa in a while. While the cuts were close, you should stack and sand the pieces for uniformity.

TIP: Rocket kit instructions always show fins being "gang sanded" against a piece of sandpaper set down on a table top. I never feel enough control doing it that way.
I find it easier to hold all three alike pieces with my left hand and square them up against a sanding block held in my right hand.
