Make sure your launch site is set for 5400, and the temperature is realistic. Double-check the mass and you should be good to go.

Radar shows 1/2" at the North site so far, with an inch to the East and West.

JUST 1 I ordered 1 pint of that Cotronics high temp epoxy. 600 deg f. $90.00Definitely be scraping every last drop off the bench with this stuff.1 gallon was a deal at $320.00I wanted to try it first,...

It was half buried in the dirt, looks like it's from last year. 54mm OD, but slightly smaller than 38mm ID.

I didn't end up fixing any of the flaws I mentioned above, and the possible slight cock of the coupler probably contributed to some coning I saw during the burn today. I prepped it on Friday, and let...

By the way, it looks like the volunteer sheet on the web site is still for last year. I'm up for some volunteer duty for this year's MHM once that starts getting coordinated.

I'd like to, but the only way I can attend this time is if I can get back to Highlands Ranch by 2:30, so I'll need to leave by noon. I have an H altitude shot I'm going to try, so I'll try to arrive ...

There are several RC airplane products that have GPS-based "return to home" functions that work with the aircraft servos. Getting the mechanical part right is the hard part for rockets. I'm starting...

Not to mention the May 7 Saturday launch on the calendar. Hopefully we'll hear about some green popping up at the north site in the next week or so. I know my lawn's weeds are springing up.

I got the F10 casing out, so the nosecone is just about ready to go. There are a few surface flaws from bubbles that I may try to fix before I fly it, or I may not, since it has such a nice polished ...

On my 38mm rockets, the plastic does not bottom out, and I can tighten it up to at least the point where there is a visible bulge in the tube from the outside. That stopper is not coming out, and it ...

Adrian, I have some old resins, I'll dig them out. Maybe at a launch we could do a transfer and I could spin one and see how it works. Edward That would be cool. Can you use my eyeballed-center sili...

That is amazing! I just hope I can get that good in the future. Remember, if the women don't find you handsome, at least they will find you handy! The nice Aluminum plug was made in a CNC lathe, by th...

If you do not have a lathe, you could use a drill press. Keeps it all vertical unless you have to turn it on it's side. I have used a drill press before for spinning things and if made strong enough, ...

Wow, and that resin has 90 second pot life, with 5-8 minute demold time. If you work out the spinning, you could crank out 10 cones in an afternoon with that stuff.
