[NSRCA-discussion] A really big thank you to everyone who madethe Weak Signals Precision Aerobtics contest a success

[Bill Pritchett]

Mike -
I sure hope you have it going now - really felt bad for you!!  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!
See ya soon -
Bill

Mike I still see my YS as a monster waiting to get me but I have managed to keep it performing well for the last 200+ flights using these guides:
 
1. The HS needle seems to be more leanient to richer settings so I have always run it at or above 2 turns out.
2. I leaned the pump a little to improve the idle but I don't think one needs to mess with it much.
3. Change the plug every 50-60 flights...I'm using OS F type.
4. Adjust valve clearences when you change the plug and keep them on the low side of the range.
5. Ensure the exit hole in the cowl is BIG...really BIG.
6. I never run the engine dry. I close the throttle at the end of the flight and de-fuel.
7. Limit the top RPM with the smaller props. I was down to 85% ATV with the 17-12...I think.
8. Use CP30 HP Heli.
 
Colin.

>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.
