uncommon to see many amps of current draw during flight. You must use a
power source that can provide the proper voltage when there is a heavy
load. Even small servos like the Hitec HS-55 can draw up to ¾ of an amp
when stalled.
Four of these servos in a "foamie" can technically draw 3
amps of current, not including the current required for the receiver.
years people have been claiming radio "failures" or "hits" with their
35MHz/36MHz/72MHz/75MHz systems that have actually been power related
and not due to signal loss.
receivers require at least 3.5 volts or they will reboot. By comparison, non-
computerized receivers will work on just fractions of a volt and never reboot.

4 cell packs. 4 cell packs will work fine with XtremeLink
you have adequate capacity. The rule that we use is no less than 350mAh
for each analog servo and no less than 500mAh for each digital servo. So,
in a typical 4 servo analog setup, a 1400mAh 4 cell flight pack would be the
absolute minimum we would recommend. Yes, you could probably get by
with a lower capacity pack, but then you have to ask yourself "what is my
model worth to me, and am I willing to take a chance with an improper
power setup?"
5 cell packs. 5 cell packs offer additional voltage headroom. These are a
better choice than a 4 cell pack. Note that some servos will not handle the
voltage of a 5 cell pack.
