[NSRCA-discussion] YS Problem

Wed Jun 3 04:10:25 AKDT 2009

Arch,
Esprit Helis (!) carries the TY-1 spinners in the US, 
http://www.espritmodel.com/index.asp?PageAction=VIEWPROD&ProdID=2452.  
However, they appear to be relabeled Great Planes spinners (or vice 
versa), as the manufacturers part numbers are identical to what I found 
on the Tower Hobbies website.  They are limited to 3" and 3.25" in the 
larger sizes, but if you have one of them, you are golden.

I've used them in smaller sizes, and they were much lighter than the 
equivalent TruTurn.  The downside is having to line up the backplate to 
the prop exactly so you can get the screws in.  I don't know how the 
length compares to the FAI TruTurns. Could be a problem if you are 
close to the 2 meter limit.

Hi Archie,

The brand I believe you are looking for is "TY-1". They are readily 
available
down here, lots of guys use them.

Which of the plastic spinners are some of the Japanese and others 
running?  I
see it has an aluminum backplate, but definitely has a plastic front.  
I have
one of the Great Planes with the aluminum backplate that I'm going to 
try.  With
the CDI, I don't mind it because it starts so easily.

Nope, bolt was gone.  I thought it might have broken also, but it 
didn't.  I
guess it just loosened up over time.  I used to make it a point to 
check it
periodically, but got out of the habit...

I had a bolt break in two, no kick, and I had the same thing happen.
Was the end of your bolt still in the adapter?  I now change bolts
semi-frequently.  Of course it had to happen in the middle of a judged
round, Jason Shulman was judging and saw it, so I zeroed the round from
that point on.

That's OK..I lost an almost brand new spinner tonight.  Didn't
have a YS kick to do it..I guess the bolt wasn't as tight as I
thought...just the
cone came off...3 week old anodized Tru Turn....grrr....

Speaking of YS and fun, I am pulling a half the niter converting
   my Black Magic to electric... Hmmmmmm Let me tell you, it was NOT fun
trying
   to get the nose ring out, damn that thing was in there good. Other
than that
  it is going fairly well actually almost done staring at it.

  a word...  Crap!

Anyone
   else??  I'd
 like a second opinion!!!! (nothing personal Anthony but
your
  opinion ..well...sucks. lol)   I have a feeling you're correct
  though, much to my chagrin.  Not having a good YS moment.

Mark,

Bad news, you can not put that back in so it does not pup out again.
     From what I have read, that problem isn't really user serviceable.
I have
     read posts of guys pressing them back in and even some guys using
JB Weld
     to keep them in. Usually that is a problem that requires the engine
to go
    back to YS.

Sorry to hear that!

Anthony

0D

The short version...    YS1.70DZ - the brass fitting on
     the TOP of the head (towards the back) that has the black check
valve
    pressed onto it blew out of the engine in flight!!  Needless to say
    the motor quit.

It appears to be a pressure fit.    I pressed it back
    in (I knew this wouldn't work, but what the heck), started the
    engine.  It idled great, ran up great, took off, and as soon as the
     motor warmed up (about two passes, pulled vertical and POP...dead 
as a
    rock.  Landed... and the fitting had popped out again.

So I have a few questions...

What caused this to pop out in the first place??

What do I do to put it back in SECURELY

HELP!!!!

-Mark
