    I’ve been “ground testing” my Jolly Logic Chute Release, and I’m pretty sure it’s a bad idea to wrap the chute with the parachute lines and then wrap the JLCR around that. It looks like a tangle just waiting to happen.

    ... this makes me wonder if there are chute designs that are particularly difficult (or unwise) to use with the JLCR — I may just lack imagination, but I can’t imagine a way to pack an annular chute and use the JLCR.

    Am I wrong? Are there chute designs that are best avoided with the JLCR?

    Yep.
    Also makes it THAT much more likely that the shroud lines will tangle up once the chute is released.

    Before you start discarding chute designs, consider changing your chute folding approach.
    The video below provides a nice illustration for a low-error-rate chute folding technique:

    I got a ringslot chute to work with it (rare to see that kind of parachute) but I have found it doesn’t like chutes more than 5ft in diameter.

    No problems with a toroidal chute for my L2, very dramatic opening.

    I've used a JLCR several times and have found that neatly wrapping a chute protector around the chute (even if it isn't needed) seems to go a long way to preventing tangles prior to wrapping the rubber band of the JLCR around it. Anyone else try this?

    In my experience....the chute material MUST be soft and "slippery". I found that chutes that have material that is STIFF (like paper) do not do well. Make sure your chutes are soft and supple and you will be good. Also follow the chute folding tutorial on the Jolly Logic website.

    Yeah, my JLCR goes outside the Nomex burrito. The only thing inside is my z-folded chute.

    I found the opposite. The one time I put the release on the outside of the Nomex, it failed. I have taken to placing the release around the base of the chute (where the shroud lines attach), then folding and rolling into the burrito. This allows the chute to act as a streamer until released.
    I should also note that I primarily only use the release on larger parachutes. (36" or larger)

    I routinely fasten the JLCR around the burrito-wrapped chute and have experienced no failures.

    Did my L2 cert flight using a Chute Release, a Fruity Chutes Parchute Sleeve and FC 48" Classic Chute without failure.

    This past Saturday I used the JLCR in conjuction with a Bama Chutes Roto-Sail without incident...other than the spectator oohs and ahs over the alternating fluoro pink and black rotating canopy.

    Seems the JLCR allows the use of a larger chute deploying at a lower altitude (200-400') for a gentle landing in the Mid Power and small H class range. Larger rockets and bigger motors seem to like a 500' opening.

    BTW, I have two JLCR's but have not yet used them in a redundant set up (series NOT parallel).

    I highly recommend the Dino Chutes JLCR pouch to protect the device.

    I’m now waiting for a BAMA Recovery Systems Tesla... here’s hoping it carries home an L2 cert in a couple months...

    My lines are NEVER wrapped around the chute, they are folded neatly up one gore and then down a different one, then folded and JLCR applied, then rolled in the blanket.

    I have been useing the JLCR since John released it. The 2 main things which has caused me issues. Make sure it's turned on and you use the right size band. The band needs to be tight around the chute.
