Thanks, Warren. Interesting history. Was Aeolus-1 the “Momentary Lapse of Reason” listed in the altitude records?

Don’t feel bad Adrian. In my quest for those Wilke records, I’ve built a successive series of 5 birds and all but the first and the last are lost somewhere out on the prairie.Aeolus 1 – Took club E record…   Read more»

First a correction:It turned out that sharing a battery between the Beeline and the Parrot wasn’t the root cause of the interference; simple proximity was. I wasted most of Thursday getting the avionics bay set up again with separate batteries…   Read more»

This is one of my favorite photograph from on board a rocket. It uses an X-form chute.Doug

@ MuleI haven’t recovered with x-shaped chutes but I have watched many of them on large mortor flares with the Army. Decent is like any other round chute just make sure to calculate the descent rates for the amount of…   Read more»

Have any of you tried cross shaped chutes?I was going to have my daughter sew me some to test out.I should have 2-29s and a 38 ready for the July launch. Possibly two 38s, but not holding my breath.

On my SSSS and J-570 i am going to use a 16-18 chute big spill hole. When your fins can withstand mach 1.5 ish it can usually handle a descent of 30 fps.

I’m planning an 18″ PML chute (huge spill hole) on an I altitude attempt sometime this summer (You aren’t safe John ;))Let’s just say that my current sim puts me in excess of the current Tripoli record :DTHAT IS AWESOME!…   Read more»

I used a single 15″ chute for “Beyond Consolation” which is roughly the same size. I reefed it, so it was probably more like 12″.I figure if it can withstand the stress of an I600, coming in at 30-35 fps…   Read more»

i actually used 2 small 12 inch chutes and it came down right over the ridge on the left of the windmill…. took an hour to find but got it back with the phenolic broken a little right above the…   Read more»

Mine (Cirrus) was on a 24″ chute, with a measured descent rate of 25 feet per second, and a descent time of around 500 seconds. If I were to try it again, I’d probably go a bit smaller, more around…   Read more»

John,I’ll also tell you how much space it takes in a 3″ diameter rocket, if I read into your reasoning correctly. EdEd, that is where I am going with this, though we all pack chutes a bit different and I’d…   Read more»

John,I’ve got one too if needed. I’ll also tell you how much space it takes in a 3″ diameter rocket, if I read into your reasoning correctly.Ed

Thanks, Doug! Do we get prizes for coming from so far away?8OJW

JW, I can bring one of mine,Doug

If the cone is laying on the ground, then it’s horizontal.I guess if it’s a lawn dart, I’ll be in trouble. I tested it today and got about 2 miles away with only minor hills in the way, after about…   Read more»

One key thing to keep in mind is the position of the actual GPS antenna. The rubber ducky whip provided with the DC is the communications antenna back to the handheld, not the GPS antenna. The GPS antenna is a…   Read more»

what is the over all length in this configuration?
