That's because i always charge somewhere between 1.8-2.0 C. For my electric planes I buy enough batteries so I do not have to hurry-charge in order to get back into the air. I charge the lipos in my starter & glow igniter at home in the shop when I have plenty of time. Now, in the interest of full disclosure, I do not use $150.00 battery packs, and none of my electric planes are for pattern.</div><div><br></div><div><span name="x"></span><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><div style="text-align: center;"><div style="text-align: left;"><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><span style="color: #8b8b8b;"><span style="font-size: 13px;"><span style="font-size: 12px;"><span style="font-size: 11px;"><span style="font-size: 10px;"><em><strong><span style="font-size: 14px;">Phil Spelt, KCRC Emeritus, Secretary<br>AMA 1294, Scientific Leader Member<br>SPA L-18, Board Member<br>(865) 435-1476v (865) 604-0541c</span></strong><strong><br></strong></em></span></span></span></span></span></span></span></span></div><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"></span></span></span></span></span></div></span></span></span></span><span name="x"></span><br></div><br><hr id="zwchr"><div style="color:#000;font-weight:normal;font-style:normal;text-decoration:none;font-family:Helvetica,Arial,sans-serif;font-size:12pt;" data-mce-style="color: #000; font-weight: normal; font-style: normal; text-decoration: none; font-family: Helvetica,Arial,sans-serif; font-size: 12pt;"><style><!--
