Optima reveivers High Voltage ???

Hello

Iīve bought five Hitecīs HS-5665 MH servos and a HS-7940TG servos, all of them are High voltage servos Iīm planning to use in a Vario benzin helicopter.

Are Hitec`s optima receivers high voltage ???

I want to use a 2 cell lipo battery directly to the receiver without a regulator. Can I do this safetly???

Optima`s manual say it can work up to 7.4 volts. but a fully charged 2 cell lipo battery has 8.4 volts. Is the optima receiver able to work safetly in 8.4 volts???

thankyou

Please refer to:
Optima Transceiver & Minima (RX) - Voltage Input Limits.

"Optima accept 2S but extremely few servos are capable of running on a 2S lipo.
"Optima voltage requirements are 4.8-7.4v being the nominal value of a 2S Lipo.
A fully charged 2S Lipo being maximum input voltage to the Servo Bus."
and more.
