Does anyone know if there has ever been a semi stowless free bag?

Councilman24, Yeah, I'd be interested in it. Thanks John

Dpreguy, No worries, lot's of info and opinions going on. I like it though. This 20yr thing got me thinking, so I decided to see if I could find information about times affect on parachutes. I thought that I had seen some studies while reading Parachute System Design concerning this but couldn't find anything in my on line copy. So, I went on line and searched and the only thing I found of any valve was a thermal degradation study. Finding on it covered 550 days at 80c resulting in strength loss of up to 46%. Now 80c is for most places unrealistic. Nothing on commutative effects though. I would think that I could have found other more relevant studies. I would think that if the studies were done the results would be used by manufacturers to inform their customers, as well as using that information to establish live limits on their products.

Councilman24, Hope to get my senior back in May but more probably June. Anyway, I'm in the process of getting seat and chest to have 1) to work toward my added ratings and 2) maintain currency once I have them. Ultimately getting my master. That could develop in to being the only master in MS and pretty close to the only master on the gulf coast. We'll see. I've already done the written and during my 20 packs did rounds too.

Hey guys, I'm looking for an email for a Philip Timothy Lynch II. He's a master rigger that according to data bases that I've looked in lives in Slidell, LA. If anyone knows him that might be willing to give me his email address that would be great. Thanks in advance, John

Dpreguy, Yep aware of the twenty year limit and 900 too much just to work toward my rating. I did look for the limit but didn't find it on Nationals web site, I didn't really go crazy digging through it though. Knew that Paraphenalia had one too. That is a big hard no on that one. Thanks for the heads up though.

Fcajump I've been looking on ebay for the mil types seats and have missed a couple of sales. Also found a National seat on there for 900. As for the pop top chest I've found the company you're referring to and talked with them about getting one. You can contact The Ranch Proshop about it. John

Anybody by chance have a manual for the Jerry Bird reserve? Also a Starmaker pop top? Thanks John

Curious, are there still pop top front mounted reserves like the Starmaker still available out there? My next project after I get my back rating is to work on getting chest and seat. So, an old military type chest and pop top. If anyone has one they may be willing to part with I'd be interested.

pchapman Thanks for the info. John

Looking for a PDF copy of the owners manual for the Raven series canopies. Reserves specifically if there's a difference. Parachutemanuals.com web site is not available. Thanks John

As many have said so far, get manufacturer and or FAA approval first. That part of the process sounds alot like field approval type deal used to make changes on aircraft without going through STC stuff. Now, with the Mojo everything is on the freebag which would make "modifying" much easier. At least I believe it's Mojo. Correct me if I'm wrong. John

Does anyone know of a bank or other lending institute that is dropzone business friendly? I'm looking for a loan to buy a dropzone. Thanks for any help. John

Just a general question. How common is it for drop zones to not have insurance? I would think more so for smaller operations. Reason for the question, I'm looking at buying a place and looking for info before or if I do this. Thanks in advance guys. John

Thanks for your response, it has given me things to think over. John

Looking to see if anyone has experience with any of Sailrite's sewing machines. Good, bad or other. Thanks John

Yep, right where I found it just a minute ago. Thanks

Never mind, found it.

Looking for a manual for the Dolphin container, hopefully a PDF. Thanks in advance. John

Thanks Mark. John

While it may be an arbitrary number I think that it at least gives you an idea about the force applied. This you could then apply to your own situation and proceed from there. Another words a "ballpark" figure to work with. Also I agree if there is no requirement through TSO then nobody really knows for sure. By the way. How do you know that the number used is Jump Shack/Racer? I'd like to know. Thanks

Funny this came up when it did, I was just reading along these lines in the riggers handbook. Anyway, you can get a pdf copy online for free. Read through Ch4. Deployment and inflation characteristics, page 4-9 there is a section on the main pilot chute. A few folks mentioned replacing your pc with a new one. That is part of what this section covers, as well as F-111 and ZP types, so all around good info. As mentioned in other post there is no firm guidance in terms of force required for the main bag pull out. However on page 4-14 there is the topic of reserve bag extraction force, which incidentally is 18lbs. So I would say that you would want your main to be close to that but you are only 7lbs from that number. Besides like also has been said wait a couple more seconds and your main will probably come right out.

You can download a copy of the FAA rigger manual, it's free. I've seen a couple of downloadable copies of the riggers study guide. Also like others have mentioned here The Parachute Manual vols 1 &2. I believe the Chutingstar has both, I got vol 1 from them.

You could look into model rocket locators possibly. There are some you can build yourself, they are audible and small. The question then is where could they be attached and how to activate them.

I'd be interested in getting a copy if the offer is still good.
