Description

Bunnell lost it's field, I will probably going to SRA in Palm Bay to launch this rocket. Started already making the charges and will continue with the prepping in the next few days. Hopefully the weather stay good.

Update 08/10/2020 - Folded the 70" parachute (X-form-Michael West), and also made two Z-ties and packed the front bay and used dog-barf, all Q-links connected.. So far weather looks ok (+/-) in Palm Bay. Also started on the booster, installed the drogue charge / dog barf / streamer (135 feet) / dog barf..... On top will be RTX / GoPro camera / WHISTLE /... to be continued...

Update 08/12/2020 - Tested the AvBay fit and sled today as well the stratologgers. All good and good fit, not a struggle like last time when I had the wrong sled with me. Nexus 4 fits in also.

Update 08/13/2020 - Installed the motor K454 SK and with two sets of O-ringson both sides. Also installed all the charges. Charging all the batteries now.

Update 08/14/2020 - Checked the weight of this fully loaded rocket without motor - 4062 + 1958 + 891 =6911 + small stuff like Nexus 4 and Tagg GPS 200 = 7111 grames.... Looks like much lighter than original calculated, or am I missing something ???

Update 08/15/2020 - LAUNCH DAY - Long drive to SRA, took off with Florence at around 7 AM and arrived at the field at 10 AM. Seems like great weather, high open skies and some thin clouds, with a lite breeze from the SW away from the swamp. Prepping went smooth Tagg and Gopro hooked up and Nexus 4 in AvBay. Deep helped me loading the rocket on the Rail. Launch was loud en swift. Streamer came out seconds later after separation, I guess wrapping the shock cord does that and it takes a while before it gets unwrapped. Rocket landed nearby south on the other side of the tree line. Deep volunteered to come with me for the recovery. I did not had any signal or GPS position from my TAGG, It does that in SRA, must be a bad signal there !! So we were looking for a red streamer, we walked kinda far off the track following the roads that we were guessing that it landed in. Nop no such luck, Deep started to walk much further away from the actual position and so did I. We finally gave up continue walking that far away. So we started searching closer by the first tree line. We guessed the the direction to the field again and YES, I could see some red of the streamer.. We recovered everything swift en got back at the field. Have video from the Nexus 5 and also from the Gopro ground. While playing he whole GoPro video I noticed that I started I fire with that SkidMark, I can see some people running with fire extinguishers and it seems that there were a few hotspots, real close to a big fire.. They got them out safe. I actually never noticed it while on the field. Was real busy following my rocket in the sky to get a pinpoint landing direction... Will replace the Tagg with the RTX again for sure. No phone data, only video. Happy that I was there, thanks Deep !

Deep just send me his remarkable set ofimages.. Thank you Sir!!!!!
