At 10 pounds, I wouldn't add any more stuff to it. You definitely have enough sheeting, in the tail alone. The light ply fuselage is quite strong just the way it is. If you have already added the bomb drop, that's the farthest I would go on this. No more. Excess weight equals a narrow flight envelope, with unforgiving stall tendencies. Get it covered, install your OS 61 FX, add skis, and go see how it works.
