I’m getting a handle on how this CafePress biz works and have found a way to get them a little cheaper, especially for you team members. I appreciate you, Ken, picking up some shirts at full price but that’s just too much. If we buy 12 at a time there is a price break and I have some other options. I’ll kick you back some bucks as well Ken. The way they have it set up ‘they’ make more profit .. not us.

Let me know what you need/want and the size and I’ll get you a price and delivery date .. to get the best deal it takes a week to get it. I can cover it for now, I have some money to play with for the next few weeks.

I think I can get them at below cost delivered. That will not fund the project but I can add $10 each and still save you considerably over buying from the store. There are price breaks at 12, 36 and 72 so if we ‘knew’ we could sell them and what sizes to order, we could add more profit to the Project.

So let’s see; 🙄 get with Joe Hinton, see what size T-shirts sell the best when he sells the shirts at MHM. See if you can get someone to help you front the money, and make sure the Proton M is ready for launch at MHM, then you can sell shirts and hats there to help recover your costs. Sell videos of the build and the launch. Use the cameras in rocket to increase the length of the video and sell it on DVD. Maybe make a calendar that tells the history of the build and the flight. Call the Discovery Channel and maybe Kari will show up with a camera crew for the launch! Now were rollin’!
I’ll take a XXL, and a medium and a Proton M hat!
See ya tomorrow.

I can tell you about T-shirt sales from doing event staffing when i was a teenager. In order of sales volume for adult audiences, along with my guesses at share:

XL (35%)
L (30%)
XXL (20%)
M (often women) (10%)
S (almost always women and children) and everything else (5%)

if you find your larges are moving too fast in relation to the others, remind anyone thats already handing you money that “this is a cotton (blend) shirt, its gonna shrink a bit”. They go for XL 80% of the time after that.

With some of the folks in our club, I’d add some XXL and XXXL’s to the size selection. I’m 6′ and at my heaviest was 215 and it took an XL or an XXL to fit me after washing. Some of our folks make me look tiny.

After talking tentative weights it looks like we will need three parachutes. One 196″ and two 160″. All are sized for under 15 feet/second descent rate. We will be using 75 yards of 66″ wide ripstop for these.

One concern is dragging after landing so I’ll be contacting Art about their landing disconnect device. Also, with these chutes it would be wise to use a deployment bag to keep recovery orderly.

I have some battery connectors on their way, and when they arrive I’ll make the booster electronics panels. Then we need to start thinking through the 2rd/3th stage electronics in earnest. I have a tiltchecker now, but I haven’t powered it up yet.

How many motors are we planning ignite in the 2nd and 3rd stages?

I hope to have all 3 airframes built by next weekend and we can start locating the electronics .. should be fairly easy as we have lots of room to work with.

The 2nd stage will be a single 75mm “L” and the 3rd either a single 54mm “K” or 3 – 38mm “I” or “J” motors. I would like the 3rd tohave something obvious and visible, like black smoke, so may go with commercial motors there. Will have to look at cost and how our funding goes .. it’s going well now but the costs really add up.

S P, boss. Show Pictures of John and Ken and Dave helping out this last weekend along with James and Rich; and we need pictures of you orchestrating the whole thing from your camping chair, even though you would not stay in it and you hurt yourself in trying to recover from the surgery and you were in great pain. And show how we are preparing to glue up the frame for the booster, and we are very close to doing that on the sustainer, and we are going to try to get that done next weekend and all those that are interested in coming should let you know what the preferred day is, Saturday or Sunday and if you are actually coming! And how we start around ten am and work until we are ready to go home or cannot work any further, and that it is really neat seeing the evolution of a 3 stage giant of a hobby rocket. (OK, maybe not as big as an S-V, 1/10th scale), but pretty big and very complicated. 8)

Don’t have any of me, on my ass or otherwise :), but here are the boys! It was a great turnout for sure.

Dave and James …… and ……..John, Ken, Dave, James and Rich.

….. and Bear joins the fun!

These motor/fin assemblies are coming out awesome. And to my surprise we are coming in very close to my proposed/estimated weights. Still just under 200 lbs fully loaded on the pad.

Thanks to all!
