Building an electronics bay for multiple rockets?

Aww man, order placed also. I guess it's only money and I've been working a butt load of overtime. Gotta spend it somehow instead of just givin it to the ex wife.

Thank you Chuck and Adrian.
You will really like these sleds.

Jeez--I was looking for these yesterday afternoon... Must of been just before they were put up. Now out of stock!!?

MWC said:

Thank you Mark, and yes, working on a 38mm version as well.

I'll buy one when you have them ready.

Much appreciated!
Here's the 38mm RRC2+ prototype with a Sparkfun PRT-10718 LiPO holder:



Also working on a 9V RRC2+ version, and RRC3 version with the Sparkfun PRT-10718 LiPO.

What kind of battery life do you get with that sparkfun Lipo on the RRC2+

I've got a pair of these charged and ready.
I'll do some empirical testing with the altimeter and battery together.

And a quick correction to the prior post, the Sparkfun battery is Li-Ion.

Have you thought about a 29mm sled?

Indeed, Landru and I are discussing a 29mm design.
Any inputs or requests?

No. I think it would have to go with a Raven or RRC2+ with a lipo.

Got mine today! Wohoo! Shiny! Can't wait to strap MWC electronics to them!

Had an oppurtunity to try this today. Here's the results of my "sim":

- Initially charged the Sparkfun Li-Ion to 4.173V
- Connected the battery and (2) 12V bulbs to the RRC2+
- Powered up the altimeter and let it chirp for a simulated 3 hour pad time.
- Voltage memasurements were : 1Hr/4.158V -- 2Hrs/4.141V -- 3Hrs/4.129V
- Popped everything into my baro chamber and made a 3 minute flight to ~3K AGL
- Let it chirp altitude for 10 minutes to simulate it sitting on the ground.
- Final voltage of 4.088V

Granted this test did not simulate an actual e-match load, however the battery seems to have plenty of ampacity for the altimeter.
