General
Can I use my own tow line?
Yes. We recommend a test of about 5 times the pull. For example
if you tow at 3 lbs, use at least 15 lb test.
How is the pull tension adjusted?
By changing the spool post positions or gear configuration. There
are two gear configurations and 5 post configurations for a total of 10
settings. Extra gears are provided for this adjustment.
Is there a guarantee or warrantee?
Yes - click here.
Can I use a hi-start with the winch?
We have not tried it.
What are the advantages over a hi-start or electric
winch?

Specs
What is the size of the winch?
15" deep x 9" wide x 9" high.
What is the pull force and distance?
The winch outputs over 1,000 ft-lbs of energy. You can adjust the
force from 3 lbs over 120 yards of pull to 16 lbs over 25 yards. Generally
we recommend a pull of about 3 times the plane weight (significantly
less than a hi-start due to the winch linearity).
Is tension really linear?
Yes it really is 95% linear due to the special reverse wound spring
arrangement.
Will the spring rust?
No - it's made of a special stainless steel.
What kind of bearings are used?
Quality steel ball bearings.
Will the Grasshopper work with a larger wingspan like
3M?
Yes. The weight is the main issue. You can launch up to a 5lb plane
but the altitude is inversely proportional to the weight of the plane. A
1lb HLG will "go to the moon". We generally recommend using it for 1 to
3 lb planes.
How is spring tension achieved?
By pulling out the line.
How does a one man launch proceed?
Please see:
http://grasshopperwinch.com/details/guide.htm.
Is a turn-around pulley needed?
No - the winch sits upwind. But you can use a turn-around if you
want the winch near you.
How do you release or start the launch?
By removing your grip of the plane.
Does the line completely retract?
No - you select how much slack you want. The slack line stays on the
ground.
