Hi all,
 
I wish to stabilize some of my soft lifters (PL Pilot, Flow form,...).
 
What is the best way for that : drogues, Legged Drogue, Piranha Drogue, Bubble Tubes, Spikey Balls, Streamer Flags, tube, tails, aso ?...

And rotating or not ?

I'm looking for the best way to stabilize a lifter kite flying sometimes from the left to the right...  Sad

I don't think that tails works very well for that ?

Many thanks in advance for your help.  Wink

You might shy away from a spinner since you'll likely be using a V line from the rear corners of the kite. If the bearing gets bound up (and they do) that will twist that V line up and pull the back of the kite together. A couple of bearings reduces the chances of that happening though if you choose to go that way. I like the looks of the Pennants & Giant Streamers myself, Gone With The Wind can supply all Gomberg Products too, they just aren't all listed. I can't say how good they are a stabilizing since they have as much lift as drag but they sure shimmer in the light and the ripple movement is mesmerizing.

I would think the drogues would have the most drag, but this is just a guess and not based on any real world use...

In other words, "I don't know"... Sad

I'd say proper tuning of the bridles or determine any other problems.

I agree with tcope.
You shouldn't need to stabilize a PL Pilot.  A pilot is meant to be stable.

A FF should only need a little drag behind it - small tubes or streamers.  Longer for more visual appeal, but they don't have to be long - they just help keep it at an AoA that keeps it inflated fully.

I'd first try to determine why they're unstable. Instability can be caused by many different things and a fix to correct one problem can make things worse if the instability is caused by some other reason.

My suggestions:
First, read through this great article on Tuning Parafoils and Flowforms by Dave Gomberg. Then read his repost of Peter Lynn's article on Flying the Perfect Pilot Parafoil. Both articles contain great information about tuning and stability.

Between those two gentlemen, you can't get much better advice.

I use one of these:


Pigs really can fly, and the inertia of mass stops the kite jumping around the wind window as the line has a deep V which is self compensating for gusts and lulls. Try it you might oink it.
