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

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 of the BlackJack propellant.

At any rate, I needed 14,003′ to exceed the current TRA record by the prerequisite 2%, but the waiver at Hartsel is 14,200’… so the boost had a 197′ window of opportunity. I trimmed the rocket for 14,200′ with appropriate added mass, field condtions, etc. I got 14,103′ on a not-quite-vertical boost, so the sim was on the button.

The bad news is that like Adrian, I landed outside the cylinder 🙁 Today it was dead calm, but I didn’t have the time or energy to do it again…

TCO has a 1.5 nautical mile cylinder, with apparently no expansion of the cylinder when the window is activated.

Congratulations, John. Dang, that’s some impressive simulation.

Any details for your rocket? Where did it land? Pictures?

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 today was because I walked 16 miles yesterday 😯

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.

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 wide band that finding the rocket was a challenge. I was getting a solid signal, even though the rocket was not line-of-site.

I landed too far away, hence my DQ. The transmitter anamoly was a first for me. I did recover, but I was half-way back to Denver by the time I picked that rocket up. Doh!
