Zoomy evening of gliding

[cgroves]

Had a nice evening flying the Fazer off the stubby winch. Had some really nice zooms with almost 2:1 climbs 110meter release and 190meter level out on one flight with only 260meters of line (130meters turnaround to winch). At one point the glider was going straight up at 115.2km/h after coming off the line wooohoooo!
There was an interesting standing wave effect with the wind coming out of the west. A wave formed just east of the treeline and generated some light lift pretty reliably.

Do you realize I read your post 3 times and still really didn't know what you were talking about.

Don't know how more complicated you could make it if you had an engine LOL

Never flown a glider, guess there's a reason LOL

Hey Fred just keep reading few more times and you will get it LOL

and may think about getting a glider. Corey so, what are ya trying to point out with image??? I am confuse..:confused: hope pic is not taken from glider

Gliders are real easy to try. There are club winches so you don't need to buy launching gear and there are some very nice entry level gliders out there for dirt cheap. The photograph shows where the standing wave formed in the wind last night. Just seeing if anyone else had experienced the same thing in the north field.

The first plot is the recording from my altimeter zoomed in to show the launches off the winch. The dip part way up is when the glider detached from the line. As you can see I almost managed to double the height from the release to leveling off which would give me a 2:1 launch ratio (total height/line height). The higher the ratio the higher the launch from a given length of line. You build up energy and speed on the line and then snap the glider almost straight up and convert the line tension into altitude. Sorta sounds weird until you've seen a strong zoom done, any clearer?

Like most things competition makes it more complicated. In recreational flying you don't care how fast you launch as long as you get up to a good altitude so most of this wouldn't matter. In F3J competitions you lose points the more time you spend on the line so the fewer seconds you are attached to the line the better. In most competitions they also dictate the line length and keep it pretty short so you need to get used to using shorter stretchy lines.
