Highlights
The April 10th launch was cancelled due to 25mph winds, mud, and cold. Todays weather was beautiful, 5 to 10mph winds, warming up to high 60s. This was the first launch of Tripoli Montana, and I launched with Paul and Dan Mazel, Pat DeWitt, and Andy Meteer. We flew for 8 hours, and had an great time. After helping my son Grant launch his Flying Saucer, I first flew my Big Bertha 3 on a C6-7 cluster. Only two motors lit, and the clip whip hung from the ignitor on the unlit motor, making for an interesting flight. The chute did deploy but it still broke one fin in half. My daughter Leah helped me launch the Alpha for a nominal flight. Next was the Arcas on a G64-7W for a nice flight. Then I launched the Hi-Tech on a H123-W. It had a nice flight except for an "Estes dent" on the payload tube, and the AltAcc reported 3388 feet. The Javelin was next on a J460-T motor, and dual deployment worked. The IA-X96 reported 3663 feet, 10.4 G's and 376 max MPH. I dusted off the PML BullPuppy and flew it on an I161-10W. It headed towards the southeast making for a long walk. Leah and I then flew the Alpha again on another C6-5. Next was Grant's Silver Comet #2 on its maiden flight with a G64-7W for a nice flight. I then flew the Mustang on an E28-7T for a nominal flight. I prepped the Javelin again and launched it on a J275-W for another good flight. Dual deployment worked as planned, and the IA-X96 reported 3646 feet, 7.9 G's and 349 max MPH. I flew the Mustang again on another E28-7T. My last flight was the Arcas on a H180-10W for another nice flight.
