BEC?

[sokal]

just wondering if i add a bec what would the benifits be?

[int2str]

None really that I can think of.

More weight :P

[sokal]

:YeaBaby:thats not a benifit lol

I believe, you will not use the internal bec from the esc and it will run cooler. It should also provide more amps to your servos.

Some ESC will drop power to the servo's on the internal BEC when the current draw is too high. Adding an external bec will allow you to run high demand servos like digitals without any problems.

+1 Basically it will pretty much ensure that your ESC will not overheat and shut down due to the extra draw your digital servos require. Summers get pretty darn hot here on the east coast it is just an insurance policy basically.Also a sport BEC and some others will allow you to run your servos at 6 volts which will speed em up.

The ESC will generate less heat, like misterg74 said.
If us get a swtiching bec it will be more efficient than a linear bec, especially in cases where people run 4s and above.
You can run 6V with most switching bec ubec etc.... but be careful, gyros don't like 6V
so you will need to run an inline 5V voltage regulator to the gyro and possibly tail servo.

This is the one that I am using, 3A Switch-Mode UBEC (http://www.takeoffandland.com.au/product_info.php?cPath=46_96&products_id=1328&osCsid=6ef3284e58744514105ec31e5eb86fea) which seems to work pretty well so far.

I heard that exact thing today from a seasoned pilot.....regarding the 401 but if you look at the specs on a 401 it says 6V is okay :confused:

Well from what I've been told by the guy at my lhs, it introduces some sort of jitter.
More than that I don't know why. I know my g110 definately does not like it.

I'm surprised that Sokal don't have AMP problems and overheat. Maybe Sokal's flying to fast that the esc is always cold. Come to think of it he has all digital around right.
