Hi All - I'm looking for recommendations for a
wing-dolly for solo assembly of the Duo Discus.
The one we have has broken for the umpteenth time.

I am very spoiled with the Lange unit that I
always use for self-assembly of my Antares 20E.
It is quick, easy, sturdy, and includes a gas-
strut to allow one-hand height adjustment (gas
spring matches weight of wing, with a lock that
is unlatched and re-latched with one's toe).
Unlike many rigging aids:
* It does not fall over while I pull the wing
out of the trailer.
* It rolls easily over uneven ground.
* It takes one hand to adjust the height, and I
do not have to crawl under the wing to adjust
the height.
* It does not lean dangerously.
* It does not damage the wing.
* It has no loose parts (two pieces in trailer)
* It requires no power
* It does not require extensive training to operate

I'm hoping to find something similarly easy
for our Duo. Any recommendations ?
Especially FIRST HAND experience from REGULAR use ?

Note that the Duo wing is HEAVY and HIGH OFF
THE GROUND. Very different from a 15m wing...

Thanks in advance,
Best Regards, Dave "YO electric"
