Must be, because aliens stole their article… that link isn’t working anymore 8)

djsroc – look me up at the launch Saturday. I’ll be driving my blue Toyota Sienna. I have something for you from Ed D.–JW

Indeed, as long as you have room (both weight and diameter), then GPS is the only way to go. Let me know when you have it whittled down to fit a 29mm rocket 8)I’m using the GPS on a project…   Read more»

Fred, the credit for the article goes to Mike Konshak – he is the whiz behind that. I just got in the way of the camera.There are a couple of receivers floating around the club, so I’d guess there is…   Read more»

it is a real dandy of a motor indeed – I like to say it is the same as an AeroTech K700 with *much* easier assembly… The fact that there is no cleanup afterwards makes it a way better motor,…   Read more»

Edward, can you give us an idea on how tight these pack down?Thanks,JW

unless I’m getting WAY up there, here is what I do for ejection charges:1. Find some LOC 0.5″ launch lug tubing. Cut this into various lengths from .075″ to 1.50″2. Get some 0.5″ dowel and cut it into 1/16″ or…   Read more»

Sean, maybe Sunday – I don’t think I’ll be there on Saturday. If I’m around, I’ll help you out.

Regarding Mike’s “soaking” question, I think Mike is asking if the epoxy will soak into the airframe – it will not, like it does on the outer layer of phenolic. Mike, if I mis-read your question, I apologize.I’ve never used…   Read more»

You cannot do a cluster or a staged project for a cert flight. From http://www.tripoli.org/cert/TRA_Certification_Rules_2009.pdf“Motor – The certification flight must be with a single certified M or larger motor (tested total impulse greater than 5120.01 n-secs). Staged and/or Clustered rockets…   Read more»

Yes, I have three executive vice presidents (Sadie, Holly, and Betsy) – all are uniquely qualified in their particular area of expertise. I may even design some kits in their honor 8)After I named the company it dawned on me…   Read more»

Thanks – it is a great way for me to keep my “toe in the water” as I fly less and less, but want to continue to hang out with the cool kids 8)

John, your description of the fin failures has convinced me to be conservative in the structural design of the fins. It would be great if we can find out some more details so that we might guess as to what…   Read more»

Great calculations, but if a layman like me understands the thoughts here, I think you are talking about stress on the fins – not the joints. The joints – not the fins – are what is worriesome. That is why…   Read more»

Gosh, I go camping for a few days and you guys have it all figured out! :DSpeaking for myself, I’m not interested in a multi-staged project. If this was recovered, then maybe stick a stage below or above it, but…   Read more»

I think it is a nifty idea that has some merit. For my part, as I feel I am probably nearer the end than the beginning of my rocketry career, I’d probably be a bit hesitant to rebuild rocket to…   Read more»

Mike, I can drive there but I can’t tell you how to get there 😯 I have spent a zillion hours flyfishing on the river a mile away and I have flown there a dozen or so times. Methinks I’ll…   Read more»

James, I had a blaring signal from the flight line. Turns out that the rocket was on the other side of the big hill east of the launch site. Somehow the transmitter got amped up and was broadcasting such a…   Read more»

Will email you directly, as there was some other stuff that happened on this flight that you will find interesting – I had my first-ever biff with a transmitter. Bottom line is that the reason I didn’t feel like flying…   Read more»

I had an interesting boost at Hartsel this weekend.As noted above, I’m a big fan of Rocksim v 4.0 as it seems to be very accurate, at least for most CTI propellants + most AeroTech loads, with the glaring exception…   Read more»
