How many RPM do you expect with the 13x6? I am thinking of pulling out my Dad's OLD Curare for SPA this season and a new engine might be in order.<br><br><div class="gmail_quote">On Dec 29, 2007 8:29 PM, Ihncheol Park <

<div style="font-size: 12pt; font-family: times new roman,new york,times,serif;">If you are going to use the engine on a Pattern plane, I would use minimum of 15% nitro & APC 13x6<br></div>
<div style="font-size: 12pt; font-family: times new roman,new york,times,serif;">If you add an extra headshim, you maybe able to run 14x5N.</div>
