Darn I sure wouldve love to see some pics on how they worked
Never heard of that company - "areotech." :confused2: And what is "propelent?" Has anyone besides Scrappy ever heard of them?How much do you think it would take to pay areotech to start making 6mm propelent kits and produce them under my name? $10k? I bet I could get rouse tech to make the hardware, problem solved

instid of carbon fiber why not use aluminum arrow shafts.
I took some rcandy and stuffed into a used mmx case after i cleaned it out even reused the nozzle. i took a drill bit and drilled out the core about 3/4 the way through so i would have a delay put some power on top of the rcandy for ejection charge. took a standard igniter for mmx and lit it. It worked and about as well as the mmx motor even had almost a 2 sec delay. but i want do it again its just to much work for what ya get
Green Monkey Aerospaces name can be displayed on TRF, not sure why people have issues with that.
6mm reloads are not that hard. reloads would be a pain to assemble but not that bad.

Green Monkey is strictly hardware.I checked out the Green Monkey website. Where do you get reloads?
Well I can see where you are going with the B and C reloads but what was the problem with the E27 reload? It really doesn't have a compeditor in the 18mm range.
Neither do I, and I think that SD realizes now how unrealistic it would be. When I showed him a MicroMaxx motor this summer, he was shocked at how tiny it was.A 6 mm reload? We're talking about 6 millimeters, correct? Isn't that less than a quarter inch? I don't get it! :confused2:

Once again, where is the market for this?making life too hard....

...interesting gentleman in
Switzerland, Mr. Torbjörn Winther, who is active in sugar rocketry, and
has made some small motors.
Very small motors.
I've placed photos of a few of his works on the web at:

You have to brew your own.
OK then. Way back when the thread started it was to ask why Company A or Company C didn't make 6mm diameter reloadable motors (or Company G or Company L). but it was so long ago I forgot how that particular question was resolved. But sure, I get what you are saying. Someone might want to build such a motor just for the coolness factor. I have been tempted to buy an RMS 18/20 motor just to have a miniature reloadable motor. It's pretty small, after all. A 6mm reloadable would be one third the size of it! As I mentioned earlier, when I met the OP at a club launch this summer and showed him an actual MicroMaxx motor, he was astonished. He told me that he had not realized how small 6 millimeters actually was. Now Quest can just barely fit 0.218 Newton-seconds of impulse (plus a vanishingly brief delay grain and a tiny but surprisingly capable ejection charge) into the existing MMX motor length (6mm x 25mm, roughly 1/4" by 1"). It's packed like an 18mm C6-7 - completely full end to end with not a hair's breadth of space left over. Granted, this is with black powder. And the opening in the clay nozzle is barely visible without magnification. In order to improve on the 1/8A impulse (increasing it to, say, 1/4A) would require a much longer case. So setting aside for now the issues of whether you can reliably cast propellant grains that small that can be handled and loaded and all of the issues with using truly tiny parts, has anyone ever successfully burned 2" or 3" long composite fuel grains that were loaded inside a 5.25mm to 5.5mm ID metal tube that was sealed at one end? Is a burn even stable and sustainable over that length within such a narrow space? I don't know what the answer is; does anyone?Not really a market at all, I thought that was a given at this point,
But, if you wanted to do it I just threw out one way to go...
the patent payment comment was a joke...
My latest patent cost around $10k by the time the dust settles. I don't think that the ROI is very promising for 6mm reloads.
While looking for something else, I re-discovered this page on 6 mm reloadable sugar motors:

Be sure to follow the "more info" links, there are several pages with a fair bit of info and pictures.
