I noticed the 4.8v brownout on planes I had just finished putting together, particularly when purposely restraining the control surface movement ( to check for servo draw ). The current draw of the servos drops the voltage, causing the problem...

I switched to 6v batteries and the problem is gone.

I don't understand why the anger over this fix though?

People are always opting for "unobtainium" servos, 2.4gHz ( when 72mHz still works fine! ), higher nitro content than they need, etc. why is this different?

Also: If you're spending "hundreds" on 6v packs, you may want to look at much cheaper alternatives...


If your 4.8v packs work fine, then use them in applications where you can employ them, or wire two together in parallel ( all it takes is a "Y" cable ) to prevent voltage drop and you're done.
