Not sure if this the place I need to ask this but, what is the better set up 4.8 or 6.0 battery packs??

Not sure either, but hear goes. Most modern radio systems can handle 6v now. Weather you need it, is another thing. I generally don't run it unless i'm looking for more speed, and or, power. Aerobatic planes will react better from the speed, and the giant scale birds I fly, like the added holding power. I run LiPos in some planes and regulate it down to 6v. With most 120 size and smaller, everyday planes, 4.8 is all I feel they need. Lotts of schools of thought hear. That's just my 2 cents.

Well, since you asked..... You might have posted this battery question in the BATTERIES AND CHARGERS forum.

But since you also asked about the value of 6V..............

If you're trying to use servos that might not be adequate in power for your application, one way to get more power out of them is to run them on higher voltage. If the servo can stand the extra available voltage they'll give you more output torque. Of course, they'll also wear out sooner and if you've got a less than good installation that stalls them, they'll be more apt to burn up.

They also move faster with higher voltage available. That is going to be harder for you to "feel" the benefit, however. You have to be rather familiar with your airplane and it will have to be one you feel is responding a bit sluggish. Very often that's because your servos aren't powerful enough, but it can also be because they're not fast enough either. Power and speed often give the same symptoms.

Not all RX nr all servos will stand the higher voltage. It's a good idea to check each component to see if it's capable of working under 6V. If you've ever read the outside of a Hitec servo box, you'll see an example of that kind of info. They list the performance of all their servos that handle 6V. They show the 4.8 specs and the 6V specs. Kinda obvious that they say their servos will take 6V.

The above info is good. My thoughts are unless you running big stuff like 1/4 scale it seems easier to just stick with 4.8 volt packs. If you want longer lasting packs pick up a pack with higher capacity. I switched the Nickel Metel batterys which have no memory in the 1400 and some are 1500 mah. I charge the pack on Friday night for Saturday morning and I can fly all weekend on these packs on the one charge.

Hey guys, don't forget to mention that with a 6.v install you have a saftey back-up with that pack that goes to 4.8 should you lose a cell. And yes I realize all the if's, and's, and but's with that type of install and what can and probably would happen before you can get the plane safley to the ground. But it is something to also consider. MM
