Slowly the sun comes up---
increased power from servos comes from increased power delivered to them --
some points to ponder .
The LiIon batts which supply power thru regulators are an assembly of bottlenecks
a resistive regulator gets hot - and will fail and will crash you -
solution - shi-t can the setup .
use cells which put out all the power YOUR servos ask for. They do exist.
Connectors we used were designed for far far lower loads than we now have available . (they heat at 4 amp loads ).
solution- parallel paths -at least until better connectors and busses become available
The easy setup would be for someone to make n market a small piggyback buss/signal bar which pushes onto existing RX buss - and has 8 amp flow type connectors .
wiring and the new bus would of course have to be a mating set.
A small mfg could do this -basically a battery to servo system which is double present setups.
anything under 33% has no need for this kind of a fix but 40+ % stuf could use it.
Ben thar-------
One more thing good switching regulators don't heat like the cheapos - The present BECs in ESC s -eare behind th curve on th higher power motors - get an external BEC- Dimension Eng has some dandy ones .

Fromeco makes a regulator with up to 3 JR type connectors to go directly into the RX. I'm using two regs with two connectors each for a total of 4 to the RX. If you read the review power supplied to the servos was not the problem, it was load on the servos for an extended amount of time (60 seconds) and also note that this is not in a stalled condition but in a simulated normal use condition.
