Deployment of the solar arrays is the next critical event. Fingers crossed. This is the first flight use of the Ultraflex solar arrays, the same design (though smaller) as the ones in the Orion des...

Woo HOO! Phoenix has landed.

Yes, a little before then. Here's the schedule: (Don't be fooled by the following being in central time. It really starts about 5:30 our time. ) 'MARS PHOENIX LANDER' TIMELINE ti...

My point - the one I keep trying to make - is that no 29mm motor exists that can compete with a 24mm motor of equivalent impulse. O.k., then send an F32 above 8422 feet and we'll talk about how an F1...

And on the bright side, it looks like the North site got over an inch of rain:

A23 cells are used with a helper capacitor on the Perfectflite altimeter, but the helper cap is bigger than the equivalent Li-poly cell. I think there may be people out there who use an A23 cell with...

I have found that if the rods of your YAGI antenna is aligned with the Beeline antenna, the signal is a bit stronger. But it doesn't make a big difference. What use were you planning for the A23 batt...

At 3/4 mile away, the beeline signal was still so strong that the pro-made yagi picked up the signal no matter what direction I pointed it. Yeah, when you get within a couple hundred yards or so it c...

The urethane cones by PML are solid, but they also have hollow fiberglass ones. I don't remember if they have hollow FG ones in 38mm. But Performance Rocketry does; I recently got a 29mm hollow FG ...

I've certainly been hooked on the record attempts. I got about as much satisfaction out of finally getting a clean, high A shot for the record as I did when I got my level 1 and 2 certs. Here are my...

That one is pretty awesome. Better than the Aiptek that I haven't gotten around to mounting yet. If I understand the manual correctly, it appears that the lens swivel can be controlled via servo. A...

I wonder what factors make the failures more or less likely to happen, and if there is anything we can do to reduce the chance of it happening. Some general questions:Does the liner burn through befor...

Yes, I'd be happy to do that too, if there were a place to put that information. It took me a minute to realize that I don't need to fly a GPS for this to work, just carry one when I go to pick up t...

Adrian [and Jim A. if you happen to read this]. Do you concur with my findings? Yep, I think you nailed it. Good sleuthing, Mike. Any luck finding the fin can yet?

According to your Rocksim plot, the sustainer would have been supersonic from somewhere around 12 seconds after liftoff to 14 seconds after liftoff. Could you zoom in on the first 20 seconds and re-...
