When SPA first allowed electric power, there was a "classic pattern" plane at a contest that sat on its landing gear at at least a 45-degree angle to accommodate the looonnnggg prop on the motor. We fixed that by limiting both the KV and prop length. Electric, under our current rules, is just as competitive as glow power, BTW.</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"><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;"><span><em><strong><span style="font-size: 14px;"> Phil Spelt, KCRC Emeritus</span style="font-size: 14px;"></strong></em></span><em><strong><br><span style="font-size: 14px;"> AMA 1294, Scientific Leader Member<br><span style="font-size: 14px;"> SPA L-18, Board Member<br><span style="font-size: 14px;"> Oliver Springs, TN (865) 435-1476v (865) 604-0541c</span style="font-size: 14px;"></span style="font-size: 14px;"></span style="font-size: 14px;"></strong></em><br><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"><span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span style="font-size: 10px;"></span style="font-size: 11px;"></span style="font-size: 12px;"></span style="font-size: 13px;"></span style="color: #8b8b8b;"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></div style="text-align: left;"></div style="text-align: center;"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"></span class="signature-truncate"><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;"><p dir="ltr">This change will drive motor manufacturers to develop lower kV motors to effectively use the power. The lower kV motors will need larger props to take advantage of the higher torque. This will mean taller landing gear to accommodate the larger props.</p>
