We've all spent time in YS hell, but I really think Colin has some good advice and I also think that the initial running at idle is what made mine work so well. I do run the 18.1x10 and although I don't limit throttle atv, am very rarely at full throttle in a flight. Sometimes a simple thing like dirt in a fuel filter can float around - like inside of a crap trap, and cause the irregular shut downs you experienced. Of course now that I've said all this it's probably my turn....... ha! Really though, my 170 has been a pleasure from day 1, has ran great all summer - I don't count flights so couldn't tell you how many, but quite a few! Hope it all works out!<br>See ya soon

<div> </div>
<div>1. The HS needle seems to be more leanient to richer settings so I have always run it at or above 2 turns out.</div>
<div>2. I leaned the pump a little to improve the idle but I don't think one needs to mess with it much.</div>
<div>3. Change the plug every 50-60 flights...I'm using OS F type.</div>
<div>4. Adjust valve clearences when you change the plug and keep them on the low side of the range.</div>
<div>5. Ensure the exit hole in the cowl is BIG...really BIG.</div>
<div>6. I never run the engine dry. I close the throttle at the end of the flight and de-fuel.</div>
<div>7. Limit the top RPM with the smaller props. I was down to 85% ATV with the 17-12...I think.</div>
<div>8. Use CP30 HP Heli.</div>

<div class="plainMail">The Weak Signals Contest was great. The quality of flying in every class, WOW!! I believe that when the competition is this good, every one flies a little better than he thinks he is capable of. With so many "old timers" in one place the amount of information and advice to be had is amazing. One thing I did learn.....listen to your coach......if she (or he) says your pattern is off center, it probably is. <br>Please keep the YS suggestions coming, they are appreciated. <br><br>Mike Murphy<br>Sent from my BlackBerry Smartphone provided by Alltel<br><br>-----Original Message-----<br>From: colin chariandy <<a rel="nofollow" target="_blank" href="http://ca.mc1126.mail.yahoo.com/mc/compose?to=cchariandy@yahoo.ca">cchariandy@yahoo.ca</a>><br><br>Date: Tue, 11 Aug 2009 07:48:15 <br>To: General pattern discussion<<a rel="nofollow" target="_blank"
