Hi all,
here is a profile model of a Cessna Skymaster.
It's build from 1.5 mm and 3.5 mm foam, then one light coat of filler and painted with permanent markers.
It flies quite nicely, I think. Charging the cap to 2.8 V is the max in my gym here so there is potential for more.
Wingspan: 360 mm / 14.2"
Weight: 11.1 g
Motors: 2 x 6x12 mm brushed motors
Supercap: 3V / 10F
Here is a short video:
Cheers
Alex
