So what size and weight of bucket are you describing and what 
diameter for the bubble wands ( I assume they are circular shaped at 
the ends to form the bubbles ) ?  

For interest - here is a repost of Peter Ulfheden's design for a 
bubblemaker - I don't think he ever built it:

My *IDEA* of a bubble maker on a kite looks like this. Note that 
I haven't tried it yet. I assume that the viscosity(sp?) of the
water will keep the speed down on the rotors.

The tank must be suspended in such way that it's aimed in the direction
of the wind. A way to do this is to it the way cameras are  suspended.

Ahhh... I couldn't resist making all those bubbles ;-)

I couldn't tell you the weight, but the bucket was app 12 x 12 x 6.  The wands
I cut off of bubble wands (app 1" diameter), and the prop was hand made.  I cut
off the end of a walnut dow rod for the center piece and whittled my own props 
from walnut stock.   It flew with the wide side to the wind and required 4
bridles to hold it in place.  It would probably be better behaved with the
narrow side to the wind and by using ping pong halves below the wands rather 
than the prop.  May have more success in lighter winds also.  Mine was crushed
in the next to last move I made, and I think that when I remake it I will try
it with the smaller sillouette to the wind and the ping pong balls.
