I need a load/watt meter to measure the amp loading correct? (I dont have one yet since I am just getting started with electrics).

The props are the stock 8x6 and it seems like it has more than a enough power and I am able to fly at about half throttle or less. Using your table, does the "C" rating on the pack need to be greater than or eaqual to the max amps draw for each motor? This does make some sense but I need more experience with all of it. Is there a generally accepted FAQ or source for this information such as one of the battery or motor manufacturers sites?

It might help me if we go back to part of my initial question- If we assume that the recomended setup of:

two motors (ignore for now what motor and assume they are correct size and draw for the battery and esc)
two esc (again correct size for application)
ONE battery 3200mAh 20C

The question is- If I replace the single battery that powers BOTH motors with TWO smaller batteries are TWO 1500mAh 10C batteries proper for this new configuration? (Can I simply divide the mAh and "C" by a factor of 2 since I am now attaching only ONE motor to a battery?

To your other response about the bec- I am running a single bec from one of the two esc's and have disabled the second by pulling the red wire from the connector of the unused unit.

Thanks for your help-

Jim
