Ok, going to post here as that is the way that I was looking to go for first while getting back into mid and high power rocketry.
Just wondering, with the advent of the Jolly Logic Chute Release, is there any difference to building an e-bay for dual deployment as far as simplicity to complexity vs costwise?
I have two Arreaux, one SD the other DD, still unfinished. I picked up the second one specifically as a DD before the JLCR came out, otherwise I would have just stuck with the SD. the JLCR fits into it no problem and has no issues on deployment. I have dozens of flights on mine, all nominal. Just sim it before you fly it in an effort to get the delay right.
There are two things that I would do different from stock.
- leave out eh motor hook and go with a retainer
- zipper proof your booster by gluing the coupler into the booster section.
The other thing that I have read on the forum is to leave out the cooling mesh and anchor point for the harness. Personally I like the cooling mesh and it makes things easier for the JLCR which they say you should not use with a nomex. I use a small amount of dog barf just for a bit of extra protection. Just one word of caution, clean the cooling mesh often, ideally after each flight. The cooling mesh is easy to clean and replace if you pick a flexible pickup claw tool https://www.homedepot.com/p/VIM-Tools-Flexible-Claw-Type-Pickup-Tool-VIMFC24/207131822
Have fun, this is a great mid-power rocket.
I thought Aerotech kits included their aluminum retainer now.

I just checked and in fact on Apogees sight it does say that it now comes with one. Sounds like Aerotech has been listening to feedback, nice looking aluminum retainer too!
Oh and I thought of one other mod, forget the lugs and go with 1010 rail buttons. For simplicity I screwed my 1010 buttons right onto the launch lugs. There are some clubs that won't allow such a relatively heavy rocket on the 1/4 rod due to the higher chance of rod whip.
I've never heard this. Where's it come from?

Gotcha. Potential risk mitigation disproved empirically.
I was particularly interested because I've been flying my L1 rocket with a chute release under the 12x12 nomex protector all year lol.
Hadn't noticed any issues, although I have the cord setup so that the nomex is close to the body tube end, and the chute is closer to the nose cone. In theory, they get pulled apart long before the release is set to let go.

I think that along with the rocket I'm looking to seriously upgrading my ground support equipment as well if all I can fly it with would be a 1010 rail.

The AeroTech retainer is not an AeroPac, the threads have a much smaller pitch. It's good to know that it's compatible with an AeroPac adapter, though.It's actually an Aero Pac retainer in an AeroTech package, I went ahead and got the 24to29mm adaptor that fits like a charm.
