What are the negatives about having a 4.8 Volt Tx battery rather than the normal 9.6 V? Is there a big enough difference to look at the Futabe 6ex instead? Thank you for your help.

Or you could look at it from the positives - 4 less battery cells to fail... If they needed more than 4.8 volts, I'm sure they would have used more batteries. Modern microprocessors are moving rapidly to 3.3 volt and 1.8 volt logic supplies, vs. the 5 volt or higher in the past. Rarely do we build imbedded processors any more at work that are higher than 3.3 volts.

Modern RF works on 3V (and lower) - it's only the dinosaurs that need more than 4.8V.

No negatives at all..

Internally the radio drops the voltage anyway. The DX6i is a lot easier to program and in my opinion nicer to hold than the 6EX - I have used both. There is nothing wrong with the futaba, it works flawlessly but in my opinion if you are choosing between those two radios go with the Spektrum.

Like this one..

I cycled the batteries yesterday and even after 33 years the TX still ran for over 3 hours.. (5 when new)

Man those aerials used to be LONG..

That old radio brings back the memories. My first was a World Engines with the rudder control on top of the stick. You twisted the knob on top of the stick for rudder. We have sure come a long way!

Well, assuming the radios use their battery packs equally efficiently, the 9.6 V pack should run for twice as long as the 4.8 V pack.
