The dx6i tx works on 4.8 volts.Whats the maximum voltage i can use on the rx?
Thanks

3.5v - 9.6v as per Spectrum website

The bigger problem is not what the RX can handle, but the servos connected to them. Many servos are only rated up to 6V. Typically, you would use a UBEC (voltage regulator) that will lower the 2S lipo voltage down to 5V or 6V:

What is your setup? Most electric planes have an ESC with an integrated UBEC so you don't need a separate receiver battery.

I will be using an electric setup,parkflyer around 30inch or so?
Micro servos and i would think 20amp esc etc..Should i be using a lipo at 7volts?
I see alot of lipos at 11.1volts would that be to much?
Thanks for the replies guys

If your ESC has a UBec, that will drop the voltage to the RX to safe limits. If the ESC does not have a Bec, install a stand alone Bec

Pretty much most 20A ESC's will have a built UBEC so you should be fine regardless of the battery you use.

This really depends on the motor and prop combination. A 3S lipo will result in more motor rpms and higher current draw. If this exceeds the motor rating, they you will likely overheat the motor and burn/melt the windings.

Do you know what make/model of motor and the size of prop?
