OS 160FX setup

[randy10926 at comcast.net]

Thanks all.  I think I have the information I need.  Plan of doing the tap the bolt hole for a V30 pump option.

Thanks for all the great information on a slow day at work.

Randy,
              The pipe provides low pressure to help feed the draw of the carb. The engine provides much higher pressure, often used with a check-valve, to operate regulators and pumps. You can't pressurize a tank with engine-pressure (3-9lbs) and expect the  carb to be able to handle the resultant fuel flow.

Regards.

Eric.

Just wondering -

Why run the pressure tap from the pipe instead of the backplate?  Also I run a greeve pipe which has no visible high point that I notice.

Wayne,

I haven't used a pump or regulator since I got the first O.S. 160FX.
Two seasons on the first with the original bearing in a heavy 2M Star.
4oz. header tank behind fire wall and 16oz. tank just in front of wing tube.
Pipe pressure from high point of pipe into main tank. No need for any
pump or regulator. Consistent runs and excess power every flight with 
unlimited vertical. 
16.5 X 12 APC, Fourstroke Y.S. plug, Mac's #1090 pipe with small diffuser-
aftermuffler added to stinger. You can guess who's header. Very quiet setup.
Will run on any fuel from 15-30%  without any noticeable change in power.

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.
