Optbig

The rocket went in under power and buried itself about 16 inches into the ground, it was required that we dig the rocket out as it could not be freed by pulling. The only damage was to the nose cone, it had a few scratches on it. This rocket which was heavily modified from the original Black Sky Plans flew perfectly and recovered on dual deployed chutes not ten minutes after being dug out. All in all, the optimal is a fine rocket that flies very straight & true with no rotation. The only draw back being that there is insufficient space in the fuselage to accommodate a decent size parachute and this also makes prepping a chore.

	As you can see from these images, the Optimal uses aluminum fins. I modified the way the fins attach to the body tube by routing into the tube and insetting the fin tabs. After assembly I used a good bit of epoxy to build fillets and totally cover all the screws holding the fins on. My understanding from others is that the designer shredded this rocket on a K1100. I plan to launch it on that and a few Kosdon's soon. I think I need have no fear of a shred after the changes I made to the fin area.
