How do you choose one? I’ve never used one and so it’s kinda hard to decide what is important and what isn’t. I’m not looking for alot of bells and whistles, but something that will reliably function for my first DD setup. I would appreciate any recommendations for specific units as well as things I should be considering when choosing one. Thanks.

I use a Missile Works RRC2X. It’s a simple, reliable unit. It isn’t the smallest unit out there, and hardly the most complex, but at $90 ($72 if you buy it from Wildman at Mayhem), it is inexpensive compared to a lot of the units out there, and it is easy to use.

I too use Missileworks RRC2X’s for most of my workhorse dual deployment rockets – the altitude resolution isn’t as fine as some, but the reliability and accuracy are great. To club members, Jim sells them for $65 so you can get an even better price than Wildman sells them for if you buy from Jim Amos directly.

In my opinion the Missleworks RR2X is the best out there. This altimeter saved many rockets and survived many crashes. The crashes btw were not caused by the altimeter.
I also use the G-wiz and it hasn’t failed me, but it doesn’t have the features that the Missleworks has.

Being that from my preliminary investigation I was leaning towards a Missileworks RR2X, you guys input sounds great. Thanks for the responses 🙂

I also use the Perfectflight MAWD, small enough to do dual deploy in a 24mm airframe, but it has problems sometimes.

Anyone know the best way to get ahold of Jim Amos?

batman,

a good choice, the one thing not mentioned and may be of irrelevance to you for now, the missileworks does not data log. A succesor is rumored to be in the works, but don’t hold your breath–Jim has many irons in the fire.

The data log lets you plot altitude vs time so you can compare ascent with a simulator–tweak Cd’s, etc which can be very helpful in contests, and also know your descent velocity.
