No you can't use a 12 vdc battery wired directly to
a RC TX.
FCC doesn't like you to incress voltage to
PA transistors in Transmitters ****There is an easy fix for it.****
Lets see 8 cells time 1.43 volts max peak
charge per cell equals (8X1.43Vdc) = 11.44 Volts. 1.2 Volts is the Average
voltage 9.6.. A Gel Cell = 12.8 Vdc Average. 12.8 - 11.44= 1.36 volts
difference at Peak (3.2Volts difference at Average Volts) NO NOT USE
without a voltage Regulator/adapter.
*********A LOW Tech way to drop
voltage*********
What you can do and would be the simplest
thing to do is to go to radio shack an buy some Silicon Diodes 1 Amp will
work or higher, and put 5 diodes ( series ) inline with the TX to
Battery wiring. Each diode drops apx .7 volts each. All diode need to be line up
alike and soldered in a long line. When you put this long line of diode in the
wiring you want the end that has the band on it in the NEGATIVE wire going to
the BATTERY. (.7 X 5 = 3.5vdc)
12.8 - 3.6 = 9.2VDC
