RE: Futaba RX's & Servos: NO Lithium Bats, 6v Max??
Hello Les..................I'm building a TF Sea Fury and I have two Futaba 9252 in my elevator and rudder. You can use a 6v rx battery as long as It's regulated down to about 5.3v. I will probably use the MPI MAXX Products voltage regulator ACC134N, it has a jumper you can cut to change from 6v. down to 5.4v output regulation. I'm refering to a Nicad RX Battery.
