BIlle, that is awesome!
You are much braver than I...
How do you start? hill, tether, run?
NOT braver than you sir ; just a $hit-load more Stupid !
The Mountain i ran off of on my flying trip, was 3,500ft , (1066-m) high
from top to bottom. With 12-mph wind ; the glider will lift me off in 2 steps ; but i hold in
to lower the AOA, so that makes me run much faster , but it's safer to
launch with more speed.
So here's a comparison between my 13m Edge , and the glider pictured above :
The 13-m Edge pulls me up out of the water at 13 knots , and tops out at about 30 knots.
The Glider is close to 16-meters,with an AR of 10, and stalls at near 16 knots , and tops out
at over 70-knots, in smooth air. So - Ya see , the airfoil on my glider , makes
for a MUCH wider speed-range , (over double the Edge) ; even though it has 3-m more aria.
Maybe LFAK would like to argue about airfoils, and what their effect is on flying machines ?
