Default To regulate 6V or not; that is the question

I am looking to go 6V on my latest project for the extra torque and have read several posts regarding the use of a voltage regulator when using 6V.
I plan to purchase the "Hobbico HydriMax 6.0V 2000mAh Flat 4/5A U Panasonic" receiver battery and am using all Futaba equipment.
S3151's & S3050

I guess what I'm wondering is what are the pro's & con's to using a voltage regulator and is it really necessary?
If it is deemed necessary then what/where do i get one. I searched on towerhobbies & found a $60 one which seems a bit pricey to me.

Thanks in advance.

Many people including myself fly 6.0 volts NiCd or NiMh systems without regulators. Look at your Futaba servos specifications, some of their digitals are not recommended to be used on 6.0 volts systems.

The only thing I have found is that Futaba give torque & speed ratings in both 4.5V & 6V for both of my servo's, so I guess that means they're OK for 6V.

I am also running into a charger dilema; I currently just have the TX/RX charger that came with my TX. I'm guessing that it will take about 4 days to charge a 2000mah battery. Looks like I get to go spend some more money on a charger.

Since the HydoMax NiMh batteries are new plan on form charging them.

That's good info.
Off topic from this forum but what charger do you recommend? At first I was thinking about getting the $30 hobbico multicharger but I think it's pretty dumb.

A constant current charger is the easiest on the packs. At C/10 rates it will take 14 to 16 hours to complete a charge. Don't leave your NiMh packs connected longer than overnight. NiMh do not tolerate overcharging well.

If you want to go to a quick charger with discharge capabilities to enable pack capacity checks. Red rates the Multiplex LN5014 as a good buy.
