At the last Tripoli launch I was at there were a number of us using the JL Chute Release. I bought my JLCR back in 2015 or 2016 when they first came out. That said, we had a number of people (including myself) have their rockets hit the ground with the parachute not unfolded. After I got my first rocket back and assessed the damage, a few of the club members came up and said that they "don't trust the chute release because they've seen it fail almost 50% of the time". At least in my case, both my flights had an open chute release on the ground when I recovered the rocket. So I assume it opened at altitude. I had the altitude set for 400ft (thinking it would lose about 100ft by the time it registered, released, and the parachute inflated). I know one guy said his chute release never popped open and another mentioned that it opened but the rubber band got stuck on the parachute and prevented the chute from opening. Previously I've always had great luck with the JLCR opening every time and the parachute inflating so I'm not sure why this time was so different for myself and others. Could it be the wind? Wind was 15mph gusting to 19mph at ground level. Also, in the past I've always set my CR to 800ft. Would the 400ft lower altitude setting be too low (read too close) for the CR to accurately determine altitude with the gusting wind when compared to ground level? Maybe it's just a parachute packing problem? Is there an update that needs to be installed? Does anybody know the failure rate of the JLCR? Just trying to think of ideas for the number of recovery failures.
