Looks like a real floater.

Nice!!! Looks very much like the Flite Test Guinea Pig.

When I die, I want to go like my Grandfather did, in his sleep...... Not screaming like the passengers in his plane.

Extend motor wires, and keep the battery wires short. Keep controller(s) close to battery(s):

Why would the TX sound an alarm? TX battery too low?

I tested the RX tonight with a stabilized power supply and actually when I lowered the voltage under 4.2 volts the radio goes into alarm, as during the crash, I therefore disconnected the BEC from the ESC and put a UBEC to power the RX (and below 4.5 volts the servos play castanets, which explains better the dive of the device ......).
The beast is ready to fly after a lot of dressing but a good shot of paint and it should do it (it looks like he did the war lol)
Following in the next video when the weather will be less rotten .....

The i6 is actually the FlySky i6 and has possibility to have Telemetry ... and as Momo has found out - he must have had it enabled ... it was warning control was lost due to lack of Rx power.

Unfortunately to lose it at 4.2V is not nice and in all fairness - there should still be control at that voltage....
