Default 4.8 VS 6 volts

Lately I"ve been reading alot from people asking about 6V airborne packs as opposed to 4.8v. Can anyone pls direct me to where I can get more info on the Why"s and How"s of this issue ?
I.e. do all servos work with both voltages?, What are the advantages and disadvantages? etc etc.


Thank you.

Most servos and receivers will work at 6v. Read the specs for the servos and receiver to be sure.

At 6V, servos are faster and produce more torque. The only disadvantage I'm aware of is the extra weight of the battery pack, which is not really a big deal IMO.

The other disadvantage is faster wear on the servos. Not all servos are rated 6v so be sure you know what you are buying.

It's also worth noting that a 6V pack will not as long as a 4.8V one (ie: a lesser flight time per charge) -- more voltage means the servos draw more current so the pack goes flatter faster.

However, in practice I've never found this to be an issue and I use 6V packs in *all* my planes now. It's like upgrading all your servos almost for free :-)

Thanks for the info, I have a question though, If this is the case i.e. better performance more power if I understand this correctly ) why do the Manufacturers not use 6V as standard issue ???

some stuff is not smooth operating with 6v -
6 v is really best for power - and if you use a radio compatible with unregulated 6v you get better power and servo speed .

Unless you use 7.4 volt lipo packs with a 6 volt regulator, then you get much longer runs, more power, and less weight.

Some equipment will be damaged by using 6V. You have to check the manufacturer's specs before just tossing in a 6V pack.
