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»

Hi Mike,Ckeck the Tripoli Colorado website, I believe they have a map there. From where you are, take I-25 south to I-70 west, I-70 West to C-470 south, C470 South to 285 south (or west?). Stay on 285 all the…   Read more»

I reserved camp sites at 11 mile Res. starting Friday Night. Probably 5 minutes from the site. Plenty still left from what I could tellThought we could shoot a couple of rockets and do some fishing ! 🙂

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»

you had a good signal before it went over the hill? what happened? Did you get back before the rain? When I drove by on 24 around 3pm looked like most everyone had already gone home.

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»

Congratulations, John. Dang, that’s some impressive simulation.Any details for your rocket? Where did it land? Pictures?

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»

Darn. If it opened at 11:15 I would have been covered.

The window opened at 11:30 and was to close at 13:30. I think that they closed it earlier because we wanted to give them the airspace back.Edward

Hmm…. My rocket landed stayed within the larger high-altitude cylinder, so this could be very close, depending on when the window for Ed’s flight was opened. Do you recall the time?Thanks.

Does that mean that the rocket has to go above 20k to have the 5 nm radius? This is good because I might get to go on another 19 mile hike :)Edward

Another couple of fun facts:Right after burnout, the rocket was going 1440 mph (Just under Mach 2.0), and had 14 Gs of drag. The burn time for the I600 was just under 2.0 seconds, which is the same thing that…   Read more»

That’s the kind of graphic sexy I can relate to. Nice shot Adrian!!!

Very nice!Where do you get the temperature corrected altitude from?Edward

Thanks Joe and Ed.I got the temperature corrected altitude from//psas.pdx.edu/RocketScience/PressureAltitude_Derived.pdfCorrecting for the fact that the ambient temperature was warmer than assumptions used in the standard atmosphere model, the peak altitude was about 16,500 feet. But if I submit this for…   Read more»

2 Nautical Mile radius on the 20,000′ AGL waiver and it gets extended to 5 Nautical Mile radius for the “windows” we used Friday and Sunday.

Lots more data (cross-posted at Rocketry Planet)Here’s more data from the new Featherweight Interface program:Altitude and temperature, for the whole flight:Velocity, accel, and altitude up through apogee deploymentZoomed into the the motor burn:I did the following post-processing using the Excel…   Read more»

Thanks! I’ve got a ton of machine work to do to get the initial sets ready, but shouldn’t be too far in the future!Edward

Let me add my congratulations Ed. Are you going to do a production run for commercial sale?Warren
