#1 Yes Arduino power on the bread board vs voltage from the RC receiver on final install voltage is 3.8Vdc

The voltage can cause the clock to change quite significantly but 30% seems excessive. 10-15% is common of the voltage range of 1.7-5.

Would installing a transistor between VCC & Reset force the clock to run at the same on both voltages?

#2 ATtiny13 @4.8MHz boards.txt located at:
C:\arduino-1.0.1-windows\arduino-1.0.1\hardware\arduino

attiny13at4.name=ATtiny13 @ 4.8MHz (internal 4.8 MHz clock)

attiny13at4.bootloader.low_fuses=0x69
attiny13at4.bootloader.high_fuses=0xff
attiny13at4.upload.maximum_size=1024
attiny13at4.build.mcu=attiny13
attiny13at4.build.f_cpu=600000
attiny13at4.build.core=core13

FWIW This has the clock/8 fuse set so it is running at 600KHz and not 4.8MHz.

Thanks, I will look up the proper fuse setting for the 4.8MHz setting
