I use a Sigma with Sigma 370 main. I like it but it is a little bit wide at the shoulder for me. So that I considered the Sigma Micro. Is there any other difference than size between standard and Micro Sigma? Anyway I have no problem to pack the Sigma 370 main into the container so I thought putting the HOP330 into the Micro would be the same. Is it not right? Robert

Other's opinion about Sigma Micro? I am just hesitating between a normal Sigma with Icarus 365 main and a Sigma Micro with HOP 330 main. Robert

Try to balance the turn with resetting the left or right steering line at the toggle. Robert

Line trim is ok? Primary/secondary brake lines? Robert

Faster how? Not altitude loss. Think about this: you have a low speed cutaway with a skyhook from a fully inflated main (lets say it's just not controllable), the skyhook does it's job and your reserve opens in 150-200'. Now, on your next jump, you have a bag lock, you cutaway, and the skyhook does it's job. Do you think your reserve is going to be open in the same 150-200' that it was in the low speed situation? I hope not! The same concept applies to any scenario where the rate of decent may be accelerated. Yes, there may be other variables such as getting deployed to the side from a spin, but which way is the reserve going to be facing when it pushes the slider down? Is it going to be facing the sky, so that it will level off quickly, or will it be facing the ground, in which case it will dive (and loose more altitude)? In time you may get a faster deployment from a spinning malfunction with skyhook, but the altitude loss is probably the same. Take account that the spinning canopy have a considerable vertical descent as well so what you win from the spinning that you loss with the vertical speed. Robert

Paratec bulletin from 09/08/2004: 'During a routine control (straightening the cable after an RSL activation) came to attention, that the swaging of a reserve ripcord pin was insufficient, causing the ripcord cable to disconnect from the pin with very little force. The same happened with 4 other ripcords (3x Next Student, 1x Next Tandem)' PdF bulletin from 09/15/2004: 'A user reported the breaking of one of the coated cables of a MMS metal cutaway handle for main canopy' UPT (RWS) bulletin from 01/30/2007: 'Ripcord damage found in field on January 18, 2007. Rig was an older Vector II.' Robert

They are talking about pro packing in the new sigma manual. Robert

Bill, Will you offer them for Sigma tandems as well? Robert

If my calculation is correct the van should go down at about 230 mph in a 20% grade to reach 45 mph vertical speed. Congratulate to the driver! Robert

I have a Jack The Ripper knife as well but some others prefer metal knifes for tandem. Nowdays a carbon fiber version appeared in the market. What do you think? Any experience? Robert

There is a good article about 'Fundamentals of Accuracy' in the Eiff Aerodynamics site: http://eiff.com/manuals/accuracy.html Robert

I am sure the cable should be out of the grommet. But it was said if you remove one pin from LOR-2, then the cable can slip into the grommet and you will be not able to pull the ripcord manually. I am not a rigger I'm just wonder the others' opinions. Robert

Since you can get the Atom Legend from PdF without the LOR-2 system, I don't see why it can't be modified afterwards. 1. Replace ripcord 2. Replace double loops 3. Remove RSL's It is in the manual, so they must be OK with that... You are right though, that modifying it to a single side RSL probably isn't endorsed by PdF and riggers who do that may open a whole can of worms, should something not work out as planned... Modifying LOR-2 to single side RSL is not permissible in Hungary. It was said that the reserve container grommet is bigger sized for the LOR-2. So if you use only one closing pin then the loop of the ripcord can go into the hole of the grommet and it will causes a hard reserve pull. Robert

And what about the burble of the tandem pair? Robert

What is safer: Doing hook turns day-to-day or doing it only occasionally when the winds are such-and-such? Robert

Riser covers have NOTHING to do with that. Please check the LAST paragraph and the LAST photo on this page: http://www.bpa.org.uk/skydive/pages/articles/dec03/cutting-away.html That's what's Bill Both and I meant few posts ago in this thread. Your misunderstanding probably comes from the fact that Bill Booth talked about TWO SEPERATE scenarios: FIRST one with a baglock and closed riser covers, and SECOND one with two canopies out (no riser covers mentioned, since that's not the problem in this SECOND scenario). No personal attack intented

Bill, I understand the "two canopies out situation" but if there is not enough drag to open the riser covers then I cannot see any difference between reverse or normal risers. Did I miss something? Robert Yes. If the risers are drawn BACK ACROSS the shoulders, there will NOT be a room for the rings to "flip" and release. In other words, the "flip through motion" will be restricted by the shoudler pressure AGAINST the 3-ring system. In other words can you imagine if your normal risers released but the riser covers would stay closed? Robert

What kind of circumstances did it happened in? And what was the tandem main? Robert
