Mike, You don't want an altimeter in the booster. The PET will work great, since it's dual, you can do both the separation charge and deployment charge. I was thinking further on the sustainer... Pi...

I wonder if using shielded or twisted pair wiring would resolve some or all of the RF coupling issue? One problem I note with most altimeters is that except for the power supply negative terminal, the...

It's really a matter of what you're looking for. I liken it (in my field) to a full functional parametric test vs. a pass/fail test. Do you want to get all the data while the rocket is in flight (i....

The DC20 transmits at 2W power. The low end Rinos are .5W and the higher end Rinos can do 5W on GMRS. BTW, 1/4 wavelength sensitivities are around the 6" range for FRS/GMRS, so ebay wiring is right i...

Putting the antenna on a short cable, it can fit in a 3" tube. By pulling the guts out of the rugged enclosure, I believe Mike said it would fit in a 54 or maybe 38mm. If Mike chimes in, he has the ...

Mike installed it in his 3" bird with the only mod being an antenna cable. By pulling the guts out of the waterproof and rugged housing, I think he said it would fit 54 or maybe even 38mm? Mike? Sur...

YES!!! Now I just need to run the "Slipstick RF Interference Test" with my Perfectflite MAWD. Thanks for the info. I'll check the Garmin site for the new FW. Ken

It's George Jetson's Dog! Ken

Warren, I've been in disk and tape drives for about 18 years now. Zero gee should have zero effect on any of these storage devices. As Mike stated, you do need air, though. The head media spacing i...

At the launches (especially the larger ones), I think it would be wise to have the signup board for ANY radio transmitting equipment, be it Adept, Rocket Hunter, Walston, Garmin dog tracker, Garmin Ri...

I'm still not quite clear on it, I guess. I thought the existing code would do a fixed "low altitude main" deployment, and apogee was up to the user to figure out. I would like a single charge at ap...

My preference (and likely that of the bulk of your buyers) is to have apogee dual deployment. Especially with altitude birds, motor delays just aren't long enough and you want it to "pop at the top" ...

Now that I want to see! Not that I'd see it once you pushed the button. 😈 That's what I like to see, Warren, nothing half-assed. That's fully assed!

Warren, Still got any of that PML "fabric core"? Some of us still use "that little stuff" 😆 I've already got a stash of assorted cardboard, so I'll pass on the lot. Ken

Correction. It will hold more motor than I can afford. 😛 Ken
