[SPAM] Re: OS 160FX setup

Randy, installing a pressure tap on the thin walled Greve isn't that bad  
except you need to get creative with how to secure the nipple. What I have done  
successfully in years past, was to drill an appropriate hole in the aluminum  
wall and install a grommet and a short piece of aluminum tubing into it. I  
have also heard that some have been successful with epoxying the aluminum  tube 
into the hole, but I have not done this myself.
 
Another option is to send the header back and ask politely for  a nipple on 
the mounting flange. Pressure is a little more variable, but  the plumbing has 
enough hysterisis to absorb the variation. In fact, that's  exactly how my 
present set-up is done.

there ain't any way I am going to touch my custom hand  made header with a drill 
bit.  Was thinking of mounting it over the  fireplace anyway.
 
I really like the hopper tank as a straight forward solution.  With  no 
moving parts it must be very reliable.  It would be very easy for me  to modify the 
battery holder just behind the firewall that I have now, over to  a hopper 
tank holder.  I have to move the battery back anyway to balance  out the swap to 
an OS160 from a Webra145.

There's absolutely no trick to the topper tank arrangement Wayne has  
referred to. It is simple set-up and works as well as any pump set-up on the  OS160 
sport engine. I have been using a 16 oz over the cg (standard tank,  not 
bladder) and a 4 oz behind the firewall for several years in a 12  pounder. 
 
The plumbing is simple as follows: pipe pressure to main tank vent;  main 
tank feed to topper tank vent; topper tank feed to carb.

On the ST2300 if you use the Perry pump you  also need to use the Perry carb. 
 I have one now that I am still  running and once its set I had to barely 
make any adjustments over the  whole season.  Putting it in a Funtana 90 right 
now...should be a  blast!!
 
Art Waggner flies FAI and uses the OS 1.60  quite successfully with no pump.  
 He runs the tank behind the  firewall and uses a bladder tank and runs 
muffler pressure.

The  instructions on the website are pretty clear.  I’ve seen one run on an 
OS 1.6  all summer, and it was flown very hard.  It was flown in a 24% Extra 
300  and I have put it through its paces numerous times, and never had an  issue 
with it.  We ran Cool  Power 15% through it, and I don’t remember ever having 
to touch a  needle.  I saw Bob is no  longer recommending this, and he has a 
lot of runs on his OS 1.6 with  the Perry pump, however I ran that Perry pump 
on a Super Tiger 2300 and  could not get it to run consistently at all, so I 
guess its all a matter  of personal preference, just like anything else we do…
the only thing you  would ever need to replace would be the diaphragm, which 
they will  replace for free.

So any tips on how to set up an Iron Bay  Regulator?  How many flights beofre 
you need to replace  one?
