Default Hitec Optima 2.4 RX batteries??

Hi, I am switching 8 glow powered planes over from 72mhx to the Hitec Optima 2.4 system. I was just wondering what I should be running for RX batteries.

I am currently running mainly 4 cell 4.8v Nicads (a couple Nimh also) and a few 5 cell 6v Nimh on my planes using the 72mhz RX's.
I have only standard servos, the biggest being some Hitec 475BB (4-6 servos/plane). Is anyone running this 2.4 system on 4 cell Nicad/Nimh?

I have read that some 2.4 systems require at least 5 cell Nicad/Nimh or the new Life (ABC) 6.6v or a Lipo and a BEC to maintain proper voltage to prevent the voltage dropping to low and browning out.

Some recommendations would be appreciated?

Thanks in advance

Curt

I've been running the 4 cell batteries for about a year now without any problems.

I have been flying Optima 6 and 7 with 4.8volt nicads since last March without problems. I have my battery monitor low level set to 4.5 volts.

I can tell you that on one .70 size bi-plane I have with 6 servos, if Irow the stick around fast and hard my monitor will beep sometimes and the low level will show 4.5 volts on the TX display after the flight. But Ihave never had any signs of control problems or failsafe lock ups even after making 3-4 flights in a row with out recharging the Rx batteries.

If Iwas buying new batteries, weight was not a problem and my servos could handle 6 volts, Iwould probably go for 6 volts in the future.
Have fun!
