<DIV>Hi Troy,</DIV>
<DIV> </DIV>
<DIV>I am going to start to use two YS 160 for this season. Could you give me general recomendations how to start, break-in and adjust these engines? Probably, you have already the information in the opinion groups so just let me have the link.</DIV>
<DIV> </DIV>
<DIV>With my best regards,</DIV>
<DIV> </DIV>

Newman" <troy_newman@msn.com> <BR><BR>> 18.1-10 is good on the 160's I don't like the W version in Arizona on the <BR>> 160. <BR>> <BR>> Now the wide version is the SNIZZLE on the 170 in AZ with the Adventure or <BR>> the Astral XXc, <BR>> <BR>> try the W in that thick FL air. I bet it will be better than the regular <BR>> version. <BR>> <BR>> I turn will turn the 18.1-10 about 8400 on the 160 and this is loud, will <BR>> not make noise. But We have been playing with the props and some <BR>> re-discovered, old techniques and I can get to run really quiet at about <BR>> 8100 and it makes noise easily and has way more punch than anything else I <BR>> have seen or flown. <BR>> <BR>> The issue now is not power. The issue is grunt and pulling the model through <BR>> tough things
like the "S" without needing high speed and yet digs the model <BR>> out of the hole on upline snaps and through windy conditions on the backs of <BR>> turnarounds downwind and so on. The time where you need the energy, yet the <BR>> model is not going to be acerbating up to Mach 2. <BR>> <BR>> Troy <BR>> ----- Original Message ----- <BR>> From: "JShulman" <JSHULMAN@CFL.RR.COM><BR>> To: "NSRCA Mailing List" <NSRCA-DISCUSSION@LISTS.NSRCA.ORG><BR>> Sent: Thursday, March 08, 2007 9:14 PM <BR>> Subject: Re: [NSRCA-discussion] YS-160 setting <BR>> <BR>> <BR>> > What prop?
