Still have my first (early 80's Alpha), flew it 2 years ago after putting a fresh shock cord in it. Still flies well after at least 3 dozen flights and 35 years.
Rebuilt my crashed Super Batray with an e-bay with a raspberry pi in it and renamed it Super Tuxray. Put a pic of Tux on the side, was well as a pi inside logo. (the 3 bump-outs are for pi-cam, microphone, and indicator leds)
Def a moonburner, check out that curve

It'll give a fun bang off the pad and then keep a nice long gentle sustain.
Finally finished the steampunk job on my ACME Spitfire (I know it's been done before, but figured I'd try my hand at it). Anyone know where the CG needs to be on this? With all the extra stuff on it (along with foaming the nose and tail transitions) I want to make sure I get it close to where...
I'm likely coming to pick up a wildman order, and watch all the cool stuff, probably won't bring anything to launch. This will be LilDuphis' first visit to an HPR launch, so we'll see what he thinks. (Mental note to get him acclimated to wearing his little earmuffs)
Another question, could someone tell me where the CG should be on this rocket? I started doing my steampunk mods to it before realizing I should have set it up completely stock first to get the CG since oddrocks like this are kinda tough to do the old fashioned way.
Is there a chance someone has a scan of the fin sheet 3 (the one that comes inside the tube, has fins 2&4 and the tailcone pattern) for the Flis ACME? Mine appears to have come without one :( Thanks!
Finally finished rebuilding my super batray that pranged due to a weak ejection/nose fit swelling in the sunlight (now renamed to super tuxray). Rebuilt it with a 5:1 nose that was given to me, and added a e-bay with a raspberry pi in it. It currently is just setup for video/audio recording...
How about an old school mono headphone jack, the kind that has the disconnect switch when a plug is inserted? Pull the plug and makes contact and completes the circuit.
I'm working on a raspberry pi zero to go in mine. It will have the mini camera and a mic attached to record the flight, and a baro sensor to act as an altimeter and backup DD computer. The Pi's are cool because you can continually tweak/modify/change/add-on to them with all of the gpio ports...
