front riser buffet

[Helopitts 0]

I am a newer jumper with 73 jumps and am jumping a Sabre2 210 that is loaded1.14. When I pull down on double fronts the parachute buffets and bucks, the same thing happens when I do front riser turns. Is this normal?

Thanks

Sounds like your brakelines are too short. See if the tail is pulled down as you pull on the fronts (it should not). If it does and you want to do anything about it, talk to a rigger.

It does sound like short brake lines.

At a safe height, and clear of traffic, do some front riser manuvers with your toggles in your hands, and look at the tail of the canopy while you do them. If there is tension on the brake line and/or it's actually pulling on the tail, the lines are too short. What's happening is you're pulling the front risers, which means 'go', and deflecting the tail, which means 'stop' at the same time.

If this is the case, speak to a rigger. You may have extra steering line stored inside of your current lines, and they can just let them out to the proper length. If not, you'll need new lower steering lines, which will take more time to build/install, but shouldn't be very expensive. Truth be told, if your lines are older, you might just have the entire steering line replaced, top to bottom, just to be safe.

Yeah. With your hands still in your toggles you should be able to pull down both front risers to your chest without deflecting your tail if you ever intend to use your fronts at all. It's very easy to let out your lower control lines.
