I am planning a Missileworks RRC2+ with either a 9V or 2-cell small Lipo for power in my Mini Frenzy. I really like how simple the RRC2+ is.
I received the Apogee EBAY today, and was disappointed that the tubes don't match the Madcow DX3. The EBAY tubes are .75mm too big. But no need to panic. I will use the tubes that came with the DX3, and fix those up so that the EBAY plywood will go inside. I just need to reduce the diameter of the four discs used at each end of the EBAY. I've done quite a bit of building of radio control and free flight airplanes, so these modifications shouldn't take more than patience. Once I get the EBAY working to where I can put it in and take it out, I will order the altimeter and battery, and of course, I will have to order the electric matches, black powder, and all the other little things that are required for dual deployment functionality.
From what I get on the specs of the RRC2+ altimeter, I will have to mount the altimeter on one side of the sled, and the battery on the other, as the altimeter is too long otherwise.
I finally got the fins seated, and now I get to try using RocketEpoxy to make the fin fillets. I've been told this epoxy is very good for this purpose. Caley Ann
I've another question on ejection charges. I've watched several videos, and seen things done differently in a few. In one, the ejection charge canisters are mounted on the EBAY ends. I've also seen one instance where the ejection charge is placed deep in the main rocket body tube below the drogue chute, and the other is mounted on the top end of the EBAY.
Does it really matter where the ejection charges are mounted, as long as the chutes and their associated lines and shock cords are protected by Nomex cloth?
Another question: If I can mount the ejection charge reservoirs to each end of the EBAY, is there a permanent solution for those resevoirs? It looks like the alternative is purchasing lots of little plastic canisters, or using rubber glove fingers. A permanent solution that looks nice is always preferable. But I do want to keep the rocket weight down. I don't want to end up with another Stretch Blobbo that was so heavy, it basically is limited to three engines, that right now are not available online.

My Mini-Frenzy has a Eggfinder Quantum and a 2s LiPo for DD.
The sled mounts on one all thread, and the altimeter sits between the sled and the other all thread. 38mm bays are very tight for space.
Wow no kidding they are tight. Well done Rich. Erik and I are keeping ours easy as that's way above his head. But I bet that flies awesome.
Finally got most of the build done. I still have to decide on how to decorate it. Right now it is a few ounces under projected weight given by the instruction manual, but that will change when I install the two chutes and Nomex hankies
Another question. Now that I have done everything for dual deployment, just how many of those shear pins do I need for the lower and upper sections. I know that on four inch diameter rockets they use three pins, but I am wondering if I need that many for this little 1.6 inch diameter rocket.
