For the guys asking about the numbers on this flight here's what I got: 13,086 ft baro AGL 52.5 G off the pad 1446 MPH (mach 1.88) The altitude and speed were much lower than I was expecting and I know this is because of the rough primered finish. I will finish painting it and polish it then fly it again and see what kind of difference that rough finish really made. The flight was perfectly straight with no wobbles so the only thing that would strip altitude and speed would be the finish. This rocket flew on a Pro38 J316 Pink. Here's a picture of the rocket loaded and then one of the paint scrubbed off the fins from aero heating. -----Original Message----- From: Chris Franco <chvy91bowtie@xxxxxxx> To: James Dougherty <jafrado@xxxxxxxxx>; TCC chat <tccrockets@xxxxxxxxxxxxx> Sent: Mon, Oct 22, 2012 12:01 am Subject: [tccrockets] Re: 5.5" PR Nike Smoke - CTI L3150 Nice picture!
