2.2" Main Chute Size

Afternoon,

I've tried to fit a 60" top-flite thin mil chute into my GoDevil 54 and it's just too tight for my liking. In OpenRocket, I simulated a 48" and it gives me a ground impact speed of 16 fps. Don't want to buy if it's not the right fit, should obviously not be as tight but, Any suggestions?

You could probably go with something like a fruity chute that would allow you a smaller diameter chute with more drag. They tend to pack a lot smaller. Problem is they are expensive. I'm sure someone will chime on on this.

Did you try to fold it so it ends up a little longer. What is the rocket weight after motor burn out? I would think you would need no more than a 36-45" thin mill chute.

I'm planning to use a 48" Spherachute in my GD54 and it fits great. I have not flown it yet (next weekend, maybe?).

My GD54 empty weight is 45 oz using weighed parts, but I won't have an all up actual weight until the paint is dry. Heaviest motor hardware I'll fly is about 45 oz, so max burnout weight will be about 90 oz. The descent rate table for Spherachutes puts it in between 15 ft/s and 22 ft/s at that weight. I don't know how Top Flight compares to Spherachutes for volume or descent rates, but there's another data point to consider.

I would highly recommend my Ultra Light Parabolic Parachutes. They are only 4 lines, very stable, and won’t tangle. They use my Ultra Light 0.66oz Ripstop with Spectra lines and thin tape for reinforcement. You won’t have any problems getting these to fit. I also manufacture High Performance Chutes with a CD of 2.21 in both the standard 1.1oz Ripstop and the ultra light version at a very affordable price. https://the-rocketman.com/ultra-light-parabolic-parachutes/

I use 36 inch BAMA chutes in my 2.1 Wild Man JR rockets all the time. No problems

What’s the weight? My Area 51 is 4lbs 1oz. I have a 4’ BAMA chute that folds up into about 1.75”x 4” and has a 16fps decent rate View attachment 408066

Damn I read this as he was wanting a 2.2" parachute and thinking woah, that's small...

I run a 48" Bama in my 2.2" Mach 1 Portia. It's more than enough for a 76 Oz. rocket. Room to spare, even with a 9 x 9" Nomex burrito

BTW, this was a single deploy launch with backup, lest you think I put the main in the wrong spot.

If you are looking for a parachute like this, I can get any design printed on 1.1 and 1.9oz ripstop on any of my 24 designs. They work great for promotions for your company or just neat designs that can’t be sewn on. Here’s a few recent examples.

I fly my L1 rocket with a 36" TopFlight , rocket weighs 4lbs on the nose. It does come in pretty quick, and I bought a 48", I think it was, to replace it; but 60" is a bit much IMO.

No sir I did not. The impeccable work was done by BAMA Chutes. Ben definitely makes the best chutes around! I have probably 15 chutes from him and every single one of them is extremely high quality.
