I am about to purchase the FrSky Taranis Transmitter with X8R 8/16 Receiver
What battery do I get for the receiver?
Any so long as it is a maximum of 10.0V - if using an ESC with a BEC you might not even need a battery.
However, it would be helpful if you gave a clue as to what the receiver is being used for. You would have got a better answer. Help us to help you!
I will put in a kit build - .46 size Mustang 4 channels + electric retracts, so 5 channel
Keep going ... High Voltage or normal voltage servos?
Still several options to decide upon ...
Normal voltage servos
Righty. Couple of options.
Assuming the motor is a nitro/glow(?) then you can either use a NiHm 6V pack or a 2S LiPo/LiFePO4 pack in conjunction with a BEC to drop their charged voltage to 5 or 6V.
If your motor is electric, then the ESC used to control it will have an inbuilt BEC ready to go.
It is a Glow so I will go with NiHm 6V and save need for a BEC
Thanks for your help - much appreciated.
Check your servos etc. can handle 6V though. A lot of servos run at 4.8 and 5V and are not happy with 6V.
