Thanks to Joe, Art, Tim, Mike S, John S and others in the club that gave me advise, casing, and stuff for this project. The J800T lite great. The boost was fast but it did weathercock a little, which I think contribute to problems later. The airstart work almost as planned. The two J350W were to light at the same time, but one took just second longer to come up to pressure. In spite this it still flew straight. At apogee the charge blew like it's suppose to. The problem was because of the weathercocking and the airstart issue it was going still going fast across the sky. This would have been OK if not for a slightly strong BP charge. My fault.
The speed at deployment, the large mass in the nose cone needed to keep CP/CG right, and the strong charge meant the sheer pins holding the NC on sheared pulling out main. The NC kept right on going a the end of the shockcord. Eric P. was right when he saw separation. I found the NC half buried by the windmill SW of the launch site. The G's broke the battery loose smashing the switch in the ebay causing a lose of power to the altimeter. Because of this there was no second event. The capacitor the altimeter pulled 90 degrees off the board. And there was a small zipper that needs repair.
All the damage is repairable. I've already come up with a new design for the NC weight and adding a second altimeter as back up. It'll fly again this fall with a great Art paint job. The bottom line it was a cool flight to see.

Ron, it was an awesome flight. I thought the entire flight was planned that way. It was really cool seeing each motor light in sequence one right after the other.
Wow.
Ken.
I concur, Ron, that was a cool project and looked great in flight! Good thing you hadn't painted it yet - I'm thinking I shouldn't paint any of my rockets before the maiden flight, just in case! Or will that just curse it?!
I thought it was a great flight and that you'd planned the airstarts just that way.

Well I was finally was able download the data from PF MAWD and the altitude was 3412 AGL. Not bad considering it didn't fly straight up the whole time. Someday I'll play with the numbers and see if I can see the airstarts.

i think Joe once said (this is an unofficial quote) "its ok if your rocket isn't painted.... it has to earn its paint!"
Vinyl contact paper works great for temporarily adding color to the airframe and fins on a 1st flight. (make sure it does not have a paper backing like what you get at the hobby stores).
The airstarts were wonderful to watch!
