How to get maximum height on a winch launch?

Should say that it's "full power all the way up" the main climb, of
course we back off at the top. But there was some suprise at the launch
point recently when a K21 waved off... the common thought was "K21s
should be able to handle it". Maybe it could if it was no wind, but
with a good headwind they just can't.

So far the sole answer to my original question has been "look at the
wingtips during the launch and find what stick position
will hold them at about 45 degrees to the horizon AND
give a safe speed. If you have a low powered winch
you may have to adopt a lesser angle" from Derek.

Does everyone agree with this?
