Yup, two parachutes. 12" for the module, 24" for the Eagle. Rigged for the Eagle to come down horizontally. Pretty much stock like the kit except for a slightly larger chute for the heavier transporter and no 18mm mount.
Forecast is calm winds this Sunday so fingers crossed.
Soooo....Eagle and flight module completely separate.

Eagle has an external shock cord mount or mounts on midsection so hangs horizontal (2 mounts would make horizontal recovery more likely than just one at CG).

Flight module recovers on its own chute vertically. Trail edges of fins look to be at right angle to long axis, so if engine sticks out a tich should minimize fin/ground impact.

Nice planning!

Hoping for smooth flight!

Well, she went up today on a D12 motor.
And skywrote all over the place. Dang.
Don't know if it was under powered or unstable.
But the Transporter survived intact except for a broken landing pad foot. Easily repaired.
Not spending any more time on this, she is now a permanent shelf queen.
Sigh.

Great effort. I am guessing that markedly irregular lobulated model just generates too much drag for your fins to account for. Not sure you’d want to risk it, but adding a ring fin outside your current flight module fins ( like a large quaker oatmeal cereal box) might give you enough finnage.

Good test flight. Trust in trust. Nice quick composite power. E and at least 15! Second flight required if only minor damage or mods needed!

Babar and Daddy,
Thanks for the feedback. She may fly again with a fin ring and composite motors.
But for now I need to take a break and clear my head.
"Trust in thrust": words to live by. Cheers.

I'd like to do a follow-up. You do need at least an E and up to some small F's. Daddyisabar is witness to my challenges with this original Kit. I have a literal 3rd rebuild in the works. After the original 18 MM configuration it was clear we needed more Power! I had a second build that went bad after apogee due to a shot gun ejection that led to a crash and burn. It has since required another rebuild as I learned a lot from the shotgun ejection SNAFU. It still harkens back to packing the dual 12" inch and single 20" chutes into a BT-50 tube. I believe I have a "final solution" (oh the humanity):rolleyes: for this issue. I will update moving forward as I get closer to full reassembly. The images below represent the second build for 24 MM engines. The 3rd build includes a longer booster using the BT-60 outer tube to house the Chutes instead of the BT-50 and a compartmented section for the 12" chutes in a transitional nose/Eagle tail insert. I've made huge strides from where the kit was (think rebuilding an eggshell) after the disastrous shotgun event.

Thanks for the update, kidagain. I like your booster.
Good luck on your third rebuild.
I might take Babar's suggestion and add a ring fin to mine.
Also have a bunch of E30s on the side.
We'll see.
