  • payload box 2 size 400×250×20 mm

Autonomous operating period provided by accumulator   8-10 hour max

Platform protections level IP64 (waterproof)

Redundancy failure level none

Self testing system  control failure detection by kite and board positioning data

Safety system kite disconnecting system trips by kite long-time overpower detection or by failure signal from self testing system. Kite disconnecting operating delay about 10 seconds
