That's my Legend. It has 11 ounces of lead in the nose, but with careful building I managed to keep it under 72 oz. I think we launched it once or twice with the One Winch. With enough tension and a good toss, not a problem.

I don't have one, and haven't seen one yet, but that onewinch looks like a pretty neat device.

This link goes to the page in the OneWinch thread where this summary apears. Post# references are in that thread.

=======================================

Field reports are around post 135 with videos starting around 159.

But this is a summary that appers around Post 88:

As with any launch method, there are advantages and disadvantages. Here is how I see it after using the Onewinch. The following assumes the pilot is working alone, doing the pulling.

I invite others to add or comment on these. The goal is not to promote or to knock the Onewinch but to recognize it for what it is, an alternate launch method.

Advantages of the Onewinch over a hi-start:

You can launch in a smaller area
If the launch goes bad you can stop the pull
No 300 foot walk to stretch the hi-star for each launch.
If you lose your grip on the plane, nothing happens.
You are not trying to lift the weight of the rubber during the launch
You are not fighting the pull of the rubber as you prepare to launch
You can keep up constant or even increasing pressure throughout the launch
You can keep the OneWinch in a car wihout concern for heat hurting the hi-start rubber
Probably smaller and lighter to pack for air travel than a 3M hi-start.
Automated rewind using a drill to drive the rewind when it is time to go home.


Disadvantages as compared to a hi-start

Once you release a hi-start you just fly the plane, no pulling
You need to back-up during the launch in order to pull.
A very strong hi-start may give a stronger pull at the start of the launch
Costs more to buy than most hi-starts.


Advantages as compare to a FLS winch

MUCH lower in cost
Much smaller and lighter to pack and carry.
No car battery to run down.
No car batteries to buy, charge or lug around
No damage to your clothes from battery acid
Less likely to damage the wings of your glider
Very low cost maintenance

Disadvantages as compared to a FLS winch

Not nearly as powerful a launch
Not nearly as powerful of a zoom
You are actively involved pulling during the launch
Pilot can become fatigued doing a lot of launches.
(have not personally experienced this)
Plane size limited by pilot strength and coordination.

=========================================

That kind of sums it up!

With the Onewinch I can launch my 1.5 poly up to my biggest sailplane which is a 64 oz Oculus. I would need at least 2 different hi-starts to do this.
