I had decided I would never push the extreme blades with stock head above 3000 rpm. With the 3s some of us are using, we max out at about 2700.
Thanks for the feedback: seems to be pretty well as I thought then.
I'm thinking of revisiting the stock 3400 motor and ESC with 3s for the main and tail (probably use the main ESC BEC to power the F45 PCB). Feel it might give the tail motor a better power balance with respect to the main: worth a try, anyway. Just can't seem to get the BL tail as good as I'd like.
But no way will I ever be spinning up the ADH300XL on 3s
