[NSRCA-discussion] YS newbie questions

[Archie Stafford]

A spare one is no longer needed with the DZ series..they are every bit as
user friendly and dependable as my OS 1.40RX's ever were.  

 

Ed, I personally prefer the AR-80 mount that Merle makes.  I've heard good
things about the YS mount also, but the AR-80 works great with this engine.


I broke both of mine in the same way.  Mounted the 18.1 X 11 that I was
going to fly, filled the tank with 30% Cool Power and went flying.  The same
was true with my 1.60 DZ.  Just didn't peak it all the way out at first,
although with how the engine gets lubricated on the front end, I'm not sure
this would be an issue. 

 

On the 1.70's I'm getting around 7800-8000 on the ground with the 18.1 X 11
and it is just stupid power.  I know others have played with other props,
but I am really happy with this setup on my Black Magic.

 In the later of the last Decade, 1998 to 2007, Crossing to the Dark side
was using an OS 2 Cycle!

Dependable, Power, and One engine will last a season or more.

 

 

 Make sure you have at least one additional YS ready when one fails.

I've finally done it.  I've crossed to the dark side and ordered a YS 170
DZ.  The coming availability of the CDI conversion promises to resolve most
of the objections that held me back before.  But now come the questions.

 

Exhaust: I guess you buy the Hatori 821 and call it a day?  Any special
mounting tips?

 

Engine mount: I've heard a little bit about an isolation mount that YS
makes, but it's pricey.  What, if anything does this buy you as compared to
a Hyde / Budd mount solution?

 

Fuel:  What's the real deal with the oil?  Not the percentage, because I
know that's being experimented with, but what oil does this engine require
in the fuel?

 

Maintenance:  I'ev heard that prior to the first run, you need to take the
head cover off and oil up the lifters.  True?  What kind of oil, how much
etc?  What about after run?  None needed?  What other maintenance tips are
there to keep this beast going?  

 

Break In:  What prop?  Lower the nitro?  Follow the instructions or is there
a better way?  

 

After break in:  What props are being used and what kind of R's are to be
expected if say, 20% nitro is used?

 

Well, that's it for now.  Any guidance here is much appreciated.

 

Thanks!

Ed
