4:00 thats interesting, because I thought the whole purpose of the B/C-bridge was to not create camber in the wing. It should engage the Bs automatically when pulling the Cs right? Otherwise it would kind of defeat the purpose, no?
If a bc bridge pulls the B at 50% the distance between A and B need to be exactly the same distance apart as between B and C. Then you have to engage the B the very moment you pull C.
@bosquo310 Correct but unfortunately if you pull backwards rather than pull down you engage more of the C lines than the B. In fact with most systems you can almost manipulate them to pull only the C's without affecting the B's at all. I feel many pilots pull back more as it's physically easier to do so but if it isn't also engaging the B's (which is why it's physically easier) if you pull bbackwards then you aren't truly keeping the gliders profile the same. I'm not sure what @ripstop_pilot means?
This is brilliant. In terms of crevats, I've often wondered if a type of net fitted around the outside of the top 500mm or so, of the lines at the tip, would help. Obviously it needs to be super light weight, like fishing nylon, to minimize drag.
From my experience so far, (60 hours which include strong conditions) i’ve only had a few minimal tip collapses. Did stop one frontal with the yank off the speedbar and for me, always some pressure on the bs. I would have had more collapses on the alpina, but i have had to up my game to respect the wing being a tier above the alpina. I do usually look at the leading edge of the wing when on bar and at least light pressure or more depending on the air.
@@syrusm 3 weeks on Photon coming from 2 years on Delta4. What an amazing glider! without question, the Photon loads up more than the Delta4, however I am a huge fan of the ACR handles, which I find more comforable than the wooden handles. The pulley system, although heavy and bulky, does a great job as a shock absorber in turbulence. I always fly D4 with no brakes and ACR handles, always pressurized unless it's smooth. I got a chance to fly the Zeno1 before I bought the Photon, which I am very grateful to have the reference of that. The Zeno1 is still a completely different animal and is vastly liftier than Photon. Photon is extremely fast on full bar, but it is not at all as lifty as Zeno1. However, Photon is so manueverable, and really spirals exceptionally well, I take it that it's because of the winglets and more arc than Zeno. Overall, the Photon is so much easier to fly than D4 in so many situations, especially toplanding, which I do a lot of daily. it has those jet flaps which are awesome! They are inefficient as hell, but nobody flies a 2 liner with brakes, so they are for what they are for and it's so easy to land and topland. When the lift is high, then it becomes like the Zeno in that it is more difficult to topland because it is very lifty, but I sure did drill the hell out of that on the D4, and it is a superb trainer for the Photon. And of course, like my friends, I haven't flown the D4 since. I never have taken anything more than a wingtip collapse on D4 in all sorts of crazy turbulence, and not even a wingtip collapse yet on Photon, but that has to be because I am religiously pressurizing my B's.
@@rondoodledix i only had one major collapse on the alpina. not on speedbar, some pressure on the rears, but it was between 2 thermals during monarca. it was an 80% deep angle, when it opened up it had to stall since not enough air in the wing. but i had so much peace of mind with it. photon is more resistant to collapses, and I've had so many good flights on it this year.
@@paraglidingSafety thanks for this. Good to see how aggressive the pump is and also a case where he had half the wind beginning to go/stall to clear it.
Brilliant!
Treasure trove of information from Russel as always.
Thxs for sharing.
nice, thx
