Well here ya go then......
............ CTI "S" motor. Cost 60,000.00 + shipping on a dedicated truck. 2.50-3.00 per mile + special fees. This one was 3,800.00 ship.
It flew to 460,000 ft.
Got some extra cash laying around? They will be happy to send one your way...:smile:
Yeah. The transportation is less than 10% of the total motor cost......and all you have to do is receive the motor at your launch site......In the grand scheme of things, $3,800 is NOTHING for shipping.
Hobby mentalities skew everything to seem expensive.

Although could it be quite possible to make a sugar motor this big? That would be an awkward grocery store visit.

Meh, they can keep their $60,000 motor. If your prepared to do it you can mix, cast, cure, and build your own. Catch is you have to do it in the field. Not that difficult, the component materials are perfectly legal to ship without permit for any part with the right formulation. 55 gallon barrels of **** can be sourced from ***** manufacturers for instance, it ***** ***** ***** *****. ***** ***** can be catalyzed to cure, you add it when it's mixed and in *****ing it makes the ***** act almost like an epoxy, it sets up. ***** powders off eBay as well as Ammonium perchlorate, that's how easy it is to get. Add in a big Hobart mixer and a curing oven made from a 55 gallon barrel and your on your way. I'm just saying for the same money the motor could be much bigger.
Best article on this I know of was in High Power Rocketry mag. Reaction Research Society made a boosted dart and cast the motor in the field. If you can find it it's a good read.
I had a thought, does shipping include and duty, import fees, customs or is it covered by NAFTA?
Wait, what?55 gallon barrels of HTPB can be sourced from paint manufacturers for instance, it acrylic enamel paint base.
Wait, what?
Same stuff, check it out. It's not cheap but much cheaper than say an epoxy based binder. I've researched components that could be used for building my own motors. I knew from years of industrial paint spraying a variety of paint systems that you can catalyze acrylic paint so that it hardens as well as dries. It then has a pot life where after a certain time it "goes off" and it all sets, just like an epoxy.
Just think about the name Hydroxyl Terminated Poly Butadiene. I know Butadiene to be a plastic, just like styrene. Poly is of course multi strand in this case. Bob would have to explain the Hydroxyl Terminated part, I never got that far in Chemistry.
A motor made with paint base has been on my agenda for a future research project. Something not from a jug marked HTPB but Olympia Paints
I dunno how wise it is to be listing all those compounds in the "non-private" portion of the forums.
That said, the compound I didn't edit out is commonly known as a material used in making motors, and so I left it.
Actually our Super Moderator Bob Krech is working on such a project with very very large sugar motors. They want to send a rocket to space powered by sugar....

All motors he sells at this time are for government use . Non civilian. He said he would like to have the regular motors certification , but what happened 20 some odd years ago it may not happen . People can't let it things go. But if you order something from him and it is in stock on the site it will be at your door in a week or less . Great kits .
Wind me up Kevin... The book is in outline format...:grin: Seriously, what Kevin said...Enough said.:sad::eyeroll:

Chris, I've heard enough claims that have more than sufficient documentation to prove them bogus that I'm going to call BS on this one until such time as irrefutable evidence is put forth.
A perfect example is the fact that DOT paperwork issued to other companies was posted for years....edited to claim they were his. Gee, guess what happened a few years later? Yep! The DOT slapped him with a fine for shipping motors without DOT paperwork.

Boy, Fred, you make it sound like someone strung you along....

Yep, they tried, "right up to the point of 40 grand to the man"...:grin:
I have to ask, what was "40 grand to the man"? I googled it and found a comment about AP, peanut butter and chocolate. What was this, some kind of AP candy bar?
