"""
- ground properties (e.g. feel bumpiness and the reduced friction of
grass or go swimming with the beaver)
- initial load for yasim gears (to get rid of the jitter the beaver has
on ground)
- glider/winch/aerotow (do winch start with YASim glider or do aerotow
over the net) I will place a how-to on the wiki soon, here very short:
use the sgs233y (or the bocian if you have AJ (up ot now) non-GPL
bocian)
winch start: Ctrl-w for placing the winch, hold w to winch, press
Shift-w to release the tow
aerotow: Place the glider within 60m to a MP-aircraft, press
Ctrl-t to tow to this aircraft. If the MP-aircraft is the
J3 and the patch is installed on both sides, the J3 feels the
forces, too. The J3-pilot has to taxi very slow up to the
moment, the glider starts moving. Increase the throttle gently.
Don't lift the J3 early, wait for the glider being lifted,
lift gently.
