I am about 4 years into running them on 50cc and 100cc planes. No regulator, no problem with any servos at all (Hitec, JR, Futaba). After the first few minutes the A123 voltage drops below the starting voltage for a 5 cell NiCd or NiMh pack anyway, and stays around 6.6 - 6.3 volts until it dumps rapidly at the end.<br>
<br>Digital servos, analog servos, etc., it doesn't matter in the vast majority of instances. The only servos that seem to have a problem are the ultra high speed Futaba heli rudder servos and gyros, which SPECIFICALLY state they are to be used with a 4.8 volt (nominal) power supply.<br>

I am running them with no regulator. I was told as long as you have digital servos, no problem.<br> <br>

<div>Running Hyperion LIFe ~800mah no regulator. I think this is similar or same chemistry as a123.<span style="font-size: 15px; font-family: Verdana;"><br></span>

<div><span>I know this has probably been asked before, but I probably didn't pay attention at the time. I'm considering using an A123 receiver pack (1800Mah) in a Synergy. Just wondering if those that are using them are also running a regulator? This is with Futaba 2.4Ghz Rx/Tx and Futaba servos.</span><br>
