The 98 worked perfect, thus vindicating the fin theory. But the tracker antenna must have ripped out at apogee as I lost signal shortly thereafter. The rocket is lost, and without the altimeters or tracker from the 98 I can't fly my other rocket, so I'm headed home. The rail buttons were gouged into the fiberglass body tube and we stripped the lower one getting it on the rail, so all I could do was glue it back on. It came off at the top of the rail and kicked the rocket at a nasty angle but it was smooth sailing from there, the motor was awesome. More later, I now really haven't slept in five days since I built the rocket, motor, and drove 1800 miles, so I'm going to drink water, head back to KC and take tomorrow off. Super bummed about losing the rocket and not flying the other one, but mission accomplished--layups are overrated. Huge thanks to Chuck Haskin, and to Bob Brown and the Kloudbusters for having me.
