BT,

What is a wiffle ball made of and what size is it and
how long do they last on the end of tow ropes?

Thanks,

John Galloway

We use a 'drag' device, wiffle balls, to help the tow
rope 'fly higher' than
with the weight of the Tost ring better clear the approach
end fence, and to
keep the rope from 'whipping' and tying itself in knots.

Of course, I'm told, that the people in OZ fly 'low
tow', below the prop
wash, so on release.. I can see where the rope will
'ascend' and possible
smack the canopy if released with any slack.

I prefer to release at or very slightly above the tow
planes altitude,
always watching the rope drop away, even with the 'drag
device'.
