That's nice because after similar experimenting a while ago I concluded that 0.5V was close enough for most purposes. In fact it doesn't even seem to matter if they're high charge rate batteries or...

Yes all the channel outputs are identical....basically the RX throttle channel has no idea whether it's driving an ESC or a traditional throttle servo ;).

You need to look at both thrust and pitch speed.

In really simple terms for props, thrust = acceleration and pitch speed = top speed and you need to balance the two.
