Peter decided to experiment with bolting two large high efficiency 6S motors to a 280mm racing quadcopter.
Peter pulled the large Avroto motors from our Helicarrier project and decided to power the entire copter with a 4200mah 4S battery.
He used a Y harness to connect the speed controller to an AUX channel on the receiver, then tied that channel to the throttle slider on his transmitter.
The maiden looked promising…until all of the support motors burned up. Peter swapped the quadcopter motors for 2208 / 2000 kv motors and took it for a second test flight.
The copter was pretty unstable, so we felt a lot safer on the other side of the shop door.
Peter successfully landed it after 9 minutes of flight time. Although we got the copter airborne and workable, the copter would be a lot more stable if the smaller motors were outside of the disc area of the center lifting prop…but that’s a project for another day.

Whenever I heard people say 6s+ is more efficient I sort of cringe because it isn't well understood. Yes the most efficient setups use higher volts, however they are using sub 200kv motors. The goal is to use the least amount of energy with minimal resistance. So actually the practical setup is to use the biggest possible prop, a flat wide stator, low KV, and lowest possible voltage to hover.

torque of the top one

I know danallen82 has said the same thing (above) but this is DOable! Both big props on top, extended arms for stabilisers - you'd end up with........well, a helicopter! Oh...
Good fun video chaps. Thanks.
