Slotted flaps

Here are a couple of detailed photos of the flap deployed and the actual geometry (from XL). You normally aim for a flap overlap and gap of around one to two percent of the wing chord, at the full deployment angle. 

The mechanism works quite well but probably wouldn't withstand a tow launch. For a glider, this type of flap is a bit impractical, but it does get the landing speed down.

Slope Flying  




What a great day, sunny and windy,
My calypso was definitely worth waiting for, and my new axle showed an amazing turn of speed with its twist wings. The calypso just screamed around the sky, then the full crow saw it gently descend, damn its good. I cant wait to put it together again.
Great day out.

 Selsley some very strong thermal lift


Nice photos Phil but you make the flying session sound like fun!!

Severe bumps/lift and then sink on the tump. Wind moved to the W bowl and I chucked off me little Weasel in a strong breeze. Huge lift, massive turbulence  and then a vacuum cleaner down draft that sucked it well down the hill. Flying control impossible. (Bermuda Triangle arrived in Glos?)

I was back in the car as the sleet and hail arrived, watching you and John get soaked as you derigged your more complicated toys.

Got home to 'you're back early on such a nice sunny, gentle breezy, Selsley at it's best sort of afternoon' as I brushed the hailstones off my jeans....Ah well, April showers I suppose....

Late afternoon the wind eased and we had gentle slope lift with smooth thermal lift

Guy's Windstar and John's FVK,

There was a light breeze blowing on to Selsley with plenty of thermal lift, but about 3.00PM it   
disappeared just as Guy arrived


I went to CLD with Nick, the wind was a little east and lift was poor
It took 13 minutes to walk up the hill slowly, see graph below
CLD is good for North and NNE,  if it's NE go to Lecky

  I flew on Selsley mid afternoon, the lift was very strong in spite of the wind being NNE, I had a go at getting to cloud base with an EPP Python, the owner was not happy
