diablopilot 2 #3 September 18, 2005 Your tandem instructors always turn in the same direction? Could be the way they are built.---------------------------------------------- You're not as good as you think you are. Seriously. Quote Share this post Link to post Share on other sites

Spizzzarko 0 #5 September 19, 2005 Is that why my velocity spins in the same direction on opening? Quote Share this post Link to post Share on other sites
billbooth 10 #6 September 19, 2005 QuoteIs that why my velocity spins in the same direction on opening? I think that most people dip their left shoulder to look over their right shoulder during opening. This can cause the left line groups to appear "shorter" than the right line groups, causing a spin in one direction most of the time. Just a theory...

matthewcline 0 #7 September 19, 2005 Bill, Coming from you it is probably a pretty good theory most don't think about. And.. it is visible on video, that and the leg kick some do to generate enough force to "throw" the pilot chute clear. MattAn Instructors first concern is student safety.

Jump Tandem drogues have to be made to extremely tight standards, or they will spin...right or left. Just a change in the thread tension in the sewing machine...even changing bobbins...is enough to do it. Think of it...it's a tiny round parachute being pulled through the sky at 120 mph for 60 seconds at a time. I'm kind of amazed they all don't spin, yet only a few do. If you have a bad spinner, we will replace it for you. Quote Share this post Link to post Share on other sites
Joellercoaster 6 #10 September 20, 2005 Would it be possible to attach one to its bridle with a swivel or bearing, so even if it did spin it wouldn't twist up?

But when you got TMs yelling "Can you get that for the next load?" All you can say is "Hang on - I'm utwtisting the f****** drogue!"

mfrese 0 #13 September 20, 2005 QuoteNot if you want the kill line to work. And trust me, you REALLY want the kill line to work, if you value your cervical vertebrae. The rigging loft at RWS actually has some nifty solutions for spinning drogues, such as the offset stitching on the reinforcement tapes, that have worked very well. As always, I'm impressed at their knowledge and ability to address these issues with creative and effective solutions.

matthewcline 0 #14 September 20, 2005 I recently (OK Today) pulled out some old video my team shot of tandems from above (promo work). The drogue does do a lot of twisting while the canopy turns. So does so many of our solo pilot chutes and it doesn't matter if it is a standard or collapsable model. But you already knew that from our conversations during the Examinor course.
