Booster stage with electronic deployment

[jrkennedy2]

Has anyone retro-fitted a booster kit to use electronic deployment? I had a LOC Terrier booster that relied on motor ejection. I had to make the ejection delay quite short (6 sec.) on a CTI I-345 White Thunder. Well, it delayed more like 3 seconds and performed a rather spectacular yard-sale, pieces everywhere on the early ejection while still climbing with authority. Prior to that, the sustainer drag separated successfully and then continued-on, on its AT H-100 DMS motor. Rather glorious, really. But I digress...

With the salvaged fin can (sans zippered section), transition cone, and some new BT and couplers, I have decided to try and put electronic deployment on it. My only challenge is, it is now about 3" longer than original. So, I am assuming it is much less to "scale" than original. The horror

How many other electronic deployment booster sections have been built out there? Love to see some cool stuff! Mine is pretty much a clod-hopper but I'm sure it will work. I could have made thing much tighter/smaller since I'm using a Eggtimer Quark to do deployment duties. My AV sled must be 4" long!

You can fit a Quantum into a 4" sled, and use one channel for the parachute and the other for your separation charge. That's what I did with my Double Shot, which is admittedly a much larger booster... I stuck an Eggfinder Mini in there too. With an I345 it's not going so high that you'll need a tracker anyway. BTW, motor eject as a backup is almost always a good option for boosters up to about K, they generally don't go high enough to run out of delay.

Of my 7 two stage rockets, all have electronic deployment on the boosters. I use a RRC2 and use apogee deploy, main deploy, and leave the motor charge as is. Some have the altimeter mounted horizontally if there is insufficient depth in the bay (interstage coupler). I use the aux channel on a RRC3 in the sustainer for the separation charge.
