Ulf,

I am running a two cell Etec 700 mah pack on my profile. I have two 6
amp. rectifier diodes in series with the receiver to drop the voltage
and still charge the pack without unhooking anything. Each diode drops
the voltage about .8 VDC, so when the lipo is hot off the charger (about
8.3 V) the receiver and servos see about 6.7 VDC. This voltage will drop
as you discharge the batteries not like a regulator. I haven't found any
other method of making it lighter than this. If you use lipos and a
regulator, you will come out a little over the weight of a 700mah nimh pack.

DON'T use an esc from electric. The escs have up to about 1 amp output
for the servos. If you run 4 standard size servos on an esc, you will
torch the chip and lose your plane. The HS85MG's can draw about 1.5A
when stalled, the HS225's about 2A. If you add this up, you need at
least 6A capability.

BTW did you ever make it to Beal Street?
