It was another fine day for flying, with clear skies and mild temperatures. I sent FLying Colors flying on it's 10th voyage, powered by a CTI 538I303-16A, to an altitude of 6374'. Everyone lost track of it, so I was forced to rely entirely on my Walston Tracker to locate the rocket. This was the first time I had to rely entirely on the tracker. It led me on a bit of a circuitous route since my rocket had landed beyond a ridge, but I did locate it.
When I returned from recovering Flying Colors we loaded a motor in my wife's Wildman Wildchild that she has named Wild Flamingo on a CTI 108G68-13A motor. My AltimeterOne altimeter was attached to the shock cord using the vendors included wire clip. When we recovered the rocket there was no sign of my altimeter and it appears to be lost for good. It was a first generation AltimeterOne which differed in a couple ways from the current product, so I'm not happy about having lost it.

Flying Season Returns
After getting several days of rain last week, the BLM cleared the launch site for use. The weather forecast looked good for Saturday, so yesterday was our first launch of the fall season.
My daughter got to launch her new Dark Star Mini on a Cesaroni 84-G88-1A to 1754'. The expected altitude was 2287', but the wind was blowing pretty good when she flew and that likely had a significant effect.
After recovering the DS Mini I flew Flying Colors on its ninth flight. I loaded an 819J354-16A, the highest impulse motor I expect to be able to load in this rocket and sent it to 8091' AGL, a new personal best. In addition to my AltimeterOne, I had my new AltimeterTwo mounted and was looking forward to getting data from it, but due to some delays after I armed it, it apparently timed out and turned itself off before launch. This flight was projected to be supersonic and I really wanted to see if I made it. I'll have to wait for spring now to see if I'm actually exceeding Mach 1 as predicted and to test if I exceed the single-axis G limit of the AltimeterTwo, as none of my remaining reloads for this season will do either of those jobs. In addition to my altimeters I was once again flying one of Vern's prototype "Kate" nose cones. She performed up to her usual high standards and did an excellent job reporting the events of my flight. Thanks to the landing coordinates she provided I was able to once again walk right to Flying Colors, which was recovered in excellent condition.
Unfortunately, due to other commitments, we were unable to stay for the entire day. The winds were calming as we left and it looked like a number of big rockets and motors were being prepped for flight.

Flying Colors, Flight #8, "A Date with Kate"
Yesterday was our final launch opportunity of the spring season. We had a very good turn out with many launches. I shot quite a lot of video, capturing 15 launches in 13 segments. There were many more launches than that, but I wasn't always in position to take video. I was there to fly my own rocket after all.
We got to the site early so we could set up our own equipment and help with the launch equipment. I was still working on setting up the weather station when other people, including the person towing the club trailer, showed up. With a number of people working on it, the range was set up well in time for the opening of the launch window at 10:00.
Vern Knowles, "parent" of the ever-popular "Kate", is working on making a version of her available for sale. Kate is an automated flight data reporting system that receives GPS data transmitted from a rocket and announces the details of the flight in near-real-time. Vern had prototype transmitters, pre-installed in various size nose cones, available for test flights at this launch. For various reasons I was the only person to take Vern up on the chance to give Kate a ride at this launch. Having Kate on-board meant I would not be able to include my Walston Tracker, which is installed in my usual nose cone. I was still able to fly my AltimeterOne, which meant I'd have two sources of data regarding my maximum altitude. The Kate nose cone is also heavier than my usual nose cone, so I anticipated a lower than estimated flight. Based on RockSim v9.0 my expected altitude was 6830' AGL. According to my AltimeterOne I reached an altitude of 6210', while Kate reported 6449'. Kate did lose GPS during the ascent, but reacquired a fix before apogee and reported data for the rest of the flight. It is a good thing she did, as I never saw Flying Colors after it left the pad. There were people that spotted it, but I think they were able to due to Kate's reporting. Since Flying Colors landed 1.33 miles from the launch site I probably would not have received a signal from the tracker if I'd been flying it, particularly after Flying Colors landed. With Kate having provided landing coordinates it was a simple matter of punching them into a hand-held GPS unit and walking right to my rocket. Thank you Vern for letting me fly your transmitter for you.
