I just completed my L1 cert with a Madcow Super DX3, single deploy, motor ejection. I put they main where the drogue would go on a DD setup and kept the NC on with shear pins.
I have up to this point planned on using the same rocket for my L2, full dual deploy with an AV bay, redundant altimeters, drogue and main.
Now that I am thinking about it further I would like some feedback on different recovery options.
Option 1 - motor ejection, drogue-less recovery with a JLCR on the main. Sims out to about 4,000 feet and change on a baby J.
Option 2 - Full DD with the AV bay setup noted above.
Option 3 - I thought of this option but am unsure of the viability. I'm not entirely comfortable with drogue-less (Option 1) having never done it. I used the braided three loop kevlar shock cord from Rocketman, main on the middle loop, for my L1, motor ejection at apogee. Here is it my question. Is it feasible to used a large streamer as the drogue to control initial descent with a JLCR on the main? The streamer would be attached to the NC, the main to the middle loop. Would that config be problematic from an entanglement standpoint? Another option would be to put the streamer on the middle loop and the main (with JLCR) attached to the NC using a shorter individual shock cord. That would position the main away from the streamer rather than directly beneath it.
I will do full-on DD with an AV bay in the future, a must for L3. With either options 1 or 3 I can go for my L2 this winter/spring. If I do a full on AV bay, given the challenges of finding viable launch windows in the Midwest corn fields, it would be late 2020 or 2021 before I can even attempt it, given build and testing requirements preceding the L2 cert attempt.
Thanks in advance...
