9 x 6 APC Thin Electric Prop
3s 5000 lipo
One cause of the under power may be the motor timing, motor says 20-30 deg but the esc default is 1 deg and the beeps for programming don't relate to the manual , even had my wife see if she could work them out, but to no avail.
Most I'm seeing on the osd is 12amps wot. Could the timing make such a difference, or do I need a different esc , motor, prop??
With a 830 kV value and a 9x6 prop you could almost run this motor on 5S (18.5V).
In my opinion the minimum to use is a 4S and then thrust may still be wanting.
With a 4 bladed prop on 3S my guess would be that you will still want more. Staying with a 2 blade prop you may need to swing 12 or 13" diameter to get respectable thrust on 3S.
So either change to a higher kV motor or change to 4S or 5S power.
Make sure not to over-amp the motor though.
