The Sasha kit looks great, I guess I need to buy one. Just curious, what are you using for the 4 coats of sealer on the balsa fins? On the more complicated builds how do you sand the balsa once it is glued to the body tubes? On simple builds I find it pretty easy to sand the balsa sealer with the fins glued on. On the more complicated builds such as Orbital Transport, Puma and others I have a challenge sanding some areas once the fins glued to the rocket.
