Take for example a common competition HG like the AEROS Combat:
- Pitch & roll control, roll neutrality in turns
- possibility for an overdrive (VG)
- no yaw-control except the glider aerodynamics (OK, this does not work exactly as in a glider...)
- L/D around 14-16 (this might even be a bit optimistic)
- same weather model...
- no cockpit, except for an altimeter, acoustic variometer and speed sensor. A GPS with basic functions may help. (The best would be to have a Flytech/Brauninger-type GPS flight instrument, but may require too much development...).
Shifting from a L/D of 50 to a realistic HG L/D (12-15) does change a lot of things when you go X-country... this yould bring a all new experience for free-flight enthousiasts, even if the models are not 100% accurate. And the possibility of a HG W-country competition... I just can't wait !!
Paraglider would be nice also (but less of my personal priority

Just hope to be heard...
