Here are some more data that i forgot to mention:
AUW was exactly 5Kg but the plane could lift that weight without a problem
and glide nicely for a brick.
Landing speed (manual landing) was awfully high (~14m/s) but it could have been as low as 11m/s
if i had flapperons installed.
Strangely the plane did not exhibit any nasty tendencies like tip stalling etc.
Being heavy also helped fight the wind gusts nicely.
Take off power was 72A * ~15v = ~1080W but it could cruise at altitude with ~16A @ 24m/s
Flight altitude was 500m ASL.
Actual wind speed at 500m was ~30Km/h according to the weather balloon we launched prior to take off (it had a VAISALA radiosonde)
Next time i will try the 2.5m diameter parachute and bungee launch.
I hope that the data i presented might found useful by someone else as the only thing that drove me to announce those tests is to add more useful information to the group and not show off.
