Separate BEC's typically are to reduce the load on your ESC (even if it has one) and keep the amps for the important equipment like your receiver and servos. It also regulates the volts to be consistent and avoid voltage spikes. In FPV it's helpful in reducing video interference.
For the Bug however it seems silly to use one because your servo loads should be very insignificant and plus you want to reduce any unneccessary weight.
If your servos fail due to overvoltage it sounds like you have a bad voltage regulator.

A BEC is a Battery Eliminator Circuit. Usually it's part of the ESC but
not all ESCs include one.
Most servos and receivers are only rated for use with voltages up to 6
volts. Using a higher voltage battery can damage them. The BEC takes
it's power from your battery and converts it to 4.8 or 6 volts and
supplies that to your receiver.
Some receivers produced lately will accept up to 7.4 volts but you
should check the receiver specs if you intend to try this. The receiver
and/or servos could fail at an inopportune time if you continue to use
an overvoltage.
And no, your glider will NOT fly longer.

Spektrum receivers and Dymond D47 servos are rated for up to 9 volts, so you can run them directly from a 2s lipo with no BEC or regulator necessary. That's how my Bug is set up, and it works great. One less thing to fail :)
With other receivers and servos you might let out the magic smoke if you connect them to more than 6 volts.

What the heck is a BEC. I just plug my LiPO pack to the receiver. Will my
glider fly longer if I use a BEC?

Hello
The need for a BEC is dependent on the battery, receiver, servo combination
you use. If you use a NiMh pack, no problems. If you use a LiPo pack, which
is good for weight, (you are trying to keep this as light as possible,
aren't you?) you have a 7v pack, which not all receivers and servos
can tolerate. If your receiver and/or servos require a 5v supply, and you
use a LiPo battery, you will need a 5v BEC. A *very* small ESC might
be tolerable to serve as a BEC, but will still cost you some weight. Are
you noticing a trend here regarding weight? The bug ain't very big and
needs to be kept as light as possible.
As for carbon booms, try Aerospace Composite Products (ACP) or CST
Composites.

Ihave started building a Lightnin Bug,this will be my first glider and I have two questions. First the plans show a BEC do I need the BEC for this to work right. I have been flying powered electric planes for a while and all of my ESC's have the BEC built into them, didnt think I would need the BEC for a glider. Where can I find the 1/8" carbon tube for the boom. Thanks for the help, great group.
