BusyBee FPV. Add gyro to increase roll stability as it is quite windy in winter. Motor mount modified to adapt 1080 propeller. With a 1000kv /3s setup, current is 16A with thrust > 600g.
Test flight for 2 times and quite satified with the gyro, which is dial down to less than45%
Flight time ~ 7 mins. with 2200mAh 3s lipo.
Mayday ...Mayday.... Emergency landing on sea...I repeat.. splash !!!
All electronics on board are submerged. Miracally, only the receiver and motor (killed by the receiver commanding full throttle , but kinked) is toasted. ECS, UBEC, gyro and servo are intact after H2O treatment. Lipo is overdischarged, due to internal short circuit to 3.3V/2.6V/ 1.5V. Slow recharging at 300mA brings it to life, but need further high current loading test to confirm re-usability.
Due to the NW monsoon and water current, it drifted to almost 2km away from the crash point in 1 hour. Finally I can fetch it with fishing wire .
Thanks Mr. fisherman to help me catching the plane with his fishing wire. He is so happy to catch a large fish that morning.
