    You are correct on the para-commander. I may have responded to the wrong post. I was replying to the difficulties of deploying a parafoil. Another (not as efficient as the para-commander) steerable round that is really easy to make is the tojo like the MC1 parachute.

    I was using a ram air foil chute and never did get it to deploy right. I don't think it was the chute that was the problem, but the heavy control tube being ejected. Getting that much mass to leave the BT was and issue.

    Some interesting stuff, guys. ;)

    What were the results that you guys saw when tugging on a regular parachute?

    We all play with our rockets, with launch and parachute drift, trying to hit the launch pad. (By the way, there are some guys that are simply amazing at this!) But if I could get close to a road, or avoid a pond (hazard at our Memphis launch site), it would make life a lot easier.

    When you say tugging do you mean pulling down a group of lines in order to slip?

    There are a few unwanted issues with slipping. The movement is not fast. It forces air out and will cause a major loss in drag. If multiple slips are performed, oscillation occurs which is far worse than anything else. Cutting vents in the rear gores (like the mc1) will allow movement and orientation.

    ^whatevs this is an update to an existing thread and conversation specific to Apogee's development.

    That's very exciting; however, I want one that can handle a 60# rocket. :(

    Why won't this work for a 60lb rocket?

    Tim said the largest chute they are making is 32".

    That is more than big enough to recover 80% of the Rockets launched. I can't wait for this to come out. I want to use it on my L3.

    True.

    What would be the max descent weight for the 32" system?

    The max weight is probably in the hundreds of pounds if deployed at apogee. Gliding chutes operate different than rounds and work off of a glide ratio. Say the glide ratio is 3:1. Regardless of if there is a 1 lb rocket or a 100lb rocket, the glide slope is the same. This means that this chute can recover very heavy payloads and not foul. I have a little experience with guided recovery on much larger items so I am pretty confident that Tim's system will find its way into much, much larger rockets.

    Huh. That's encouraging. Thanks.
