Hi Mike,
Nice catch. Now I need to remember where it is when I fly it.
Yes, i'm using a UBEC.
My current measurements with both the 16-cell 1950mAh NiMH pack and the 4s4p Kokam 8AH pack were about 30amps (450 watts).
This is 10amps under my expected number and likely due to the AeroNaut folding prop so I have ordered several sets of bigger blades.
Although the power looked good enough to test fly, at 30amps I'm not taxing anything in my power system so I want at least a 40amp draw to start with.
More soon...
