I agree. 4,400 20C Sky Lipos are perfect for your plane at under 20 oz and less than 50 bucks. What more can you ask for. I flew them all this year, but have moved to 40C 4,400's for Masters. <br><br><div class="gmail_quote">

<div>I've been flying Intermediate with my
Abbra with a Hacker C5-14XL (not the comp version) for a while
now. For Intermediate flying/practice I generally use around 2,800
mAh of capacity for a 7.0 minute flight. I was using 5,000 mAh
packs but recently switched over to 4,400 20C cells. My packs are
never hot and rarely exceed 110 deg F. I have a claculated average
load of around 25 amps. I am only using 65% to 70% of the pack
capacity.<br>
<br>
So for me, my pick is a 4,400 20C pack. Works perfectly. I've been
using the Sky Lipo from Hobby Partz and at $45 a pack ($90 for a
10S) it is hard to go wrong with them.<br>
<br>
Just another data point.<br>
