But what if the rx pack goes south?  Then what is left is garbage.  If a
cell goes bad on the motive pack with a UBEC installed, you still have power
to control the servos.

If no one has mentioned it don't forget to look at Neu motors.  I am running
a 1506 2D 6.71 gearbox on 10 GP 3300s with terrific results.  80 amps with
an 18x10 prop in an electric Escape.  It's smoother than a Hacker and I can
talk to the people who built it on the phone.
I had some range issues with a UBEC too.  Now that I have a little 4 cell
AAA pack in there the worry of motive pack failure is gone as are the range
issues.  If a cell goes bad in the motive pack or something else it's still
a glider!

Have a look at http://www.rcgroups.com/forums/showthread.php?t=3D440307.
It's about the crash of a Stratos SL/e, tentatively blamed on an SBEC,
which is a stand-alone battery eliminator.

Rethinking, yes, of course! But one of those gizmos that replaces a rx
battery saves a lot of weight.

And yes, form factors when it comes to Li-Ion packs can make them
impossible to use - but check around, there are many brands!

Sensorless Hacker controllers are a blessing, after having used AVeox's
sensored, 'nuff said :-)!
