Futaba receiver, high voltage
 

Hi everyone,

I'm about to upgrade my ESC to Hobbywing's with a built-in BEC as I have new, high voltage servos. I'm a bit confused about which ones actually supports high voltage though. (The reason for this confusion is that Futaba sells a receiver that says it's for high voltage explicitly.)

Anyway, I have a couple of R304SB-E and R324SBS and the operating voltage is rated between 4.8-7.4 volt and usable voltage between 3.5-8.4 volt*. Would this mean it supports 7.4 volt or is operating voltage different? (Can't link to the manual as I haven't posted enough posts yet.)

I have never had any problems operating my Futaba receivers at 8.4v
