Why isn't 8.4v listed as the power requirement range? It doesn't make sense to me to have 8.4v listed only as a usable voltage since the R6303 can handle 8.4 input voltage (i.e. from a BEC) as per the manual. What am I misunderstanding? I want to run 8.4v in all of my electronics.

R6303SB http://www3.towerhobbies.com/cgi-bi...1P?I=LXCHXE&P=8
which says:
Power Requirement: 3.7-7.4V, Usable voltage 3.5-8.4V

In my opinion, the phrase "usable voltage" is better suited to describe what minimum voltage to maintain. I don't understand what context this is for the upper end of the voltage range.

So the total allowed range is 3.5 to 8.4V. Run your 8.4V.

E820, Raptor G4N, X50F/E, E620, Forza 450, and some planks.

The manual says-

The input voltage must not exceed the servo rating or 8.4V which ever
is lower.

I would ignore tower's wording of "usable".
