V4 leg wing fluttering/vibrating Can't Post

Having a problem with a V4 where the leg ving is giving quite strong vibrations. Anyone with the same problem?

There was a small problem with a few production models due to some some small variations in how the leg-inlet was constructed by one of our workers.

Contact PF directly via info@phoenix-fly.com and we will fix/update your suit free of charge to the production standard that PF is known for.

talked to robert and tried to cut some of the material from the inlets but get the same result. so was wondering if there could be any other reason besides that

I've seen two different v4 suits that have had a legwing flapping issues, it looks like the legwing kind of deflates and starts flapping in a dive, but I just saw a brand new one that didn't do it, so I'm hoping they got the problem solved. still waiting on the arrival of mine Unimpressed

Its not an issue on 99% of all V4s out there. But like any product, every once in a while there is one that doesnt behave as it should. In that case we try and get the issue resolved.

To the OP, Robert commented you had notified him previously the issue was fixed. If you can get back to him, and further elaborate we can sort out the issue directly with you. As direct contact with the manufacturer who can assist is always quicker than posts on a forum.

I also found rolling your knees outwards and overly pointing toes (old habit from my previous wingsuit that was std sizing and didnt fit correctly) to tension the forward to mid part of the wing made things worse. conversly spreading my legs while keeping my knees facing forward without overly poining toes(though didnt feel like the legwing was held as tight) reduced the problem. may not be relevant to you but might be worth a try.
to me it always seemed like the flap was airspeed related, i would start flying a little steeper, no flap then after i reached a certain speed violet flap would start and would remain and get worse the faster i went if i flattened out it would remain until i slowed till i was below that certain speed, attitude was irrelevant. I could never see the legwing but it never felt like it was depressurised. good luck

I have to say - I am very happy with my suit, and customer service. This was ment as a question regarding possibly wrong body position not the suit itself. Very happy with PF :)
