[NSRCA-discussion] Venus Engine Question

Fri Jul 4 07:52:20 AKDT 2008

Thanks all for the info. I believe I will go with the Perry. Adding a
pressure tap to the back plate is not a problem but I may get the special
back plate screw the 1.40 uses and extend one of the holes in the crankcase.
I may try it without the pump first but suspect the transition may lag. I am
ironing on the paint while waiting for the backordered pipe.

I once installed a Kline in my Focus which had a 150 2 Stroke in it and the
pressure generated by that particular engine was too high, causing the thing
to load up, so I installed an after-market needle valve in the pressure line
and adjusted the available pressure to the tank and it seemed to work quite
well.

The Perry doesn't require the tank to be pressurized like the Kline does. On
the other hand, I believe the Kline can be run with muffler pressure to the
tank whereas the Perry needs crankcase pressure to the pump. This can be a
pain if you don't feel like tapping the backplate of your engine. Either
system can work very well or very poorly. You'll find that people will swear
by either one but not necessarily both. I personally have had better luck
with the Perry so that's what I use.

Jay, how does the Perry pump compare to a Kline?

I used the Perry VP-30 and an APC  15-10 prop.

Thanks.  What prop are you using and what is the Perry Pump model number
that you are using?

I added ½ oz. It will depend how heavy your servos are. I used a different
fuel tank and moved it back to the wing tube to keep the CG constant. This
necessitated a Perry pump.

Jay,

Did you have to add weight to the tail to balance the plane?  If so, how
much weight did you add?

I use the stock muffler. The engine is mounted so that the muffler is at the
bottom of the fuse. This puts the head at appx 8 o’clock.

Jay,

Are you using the stock muffler on the AX or something different?

Sound doesn’t win! Go with the AX – lots more power, more reliable. (I have
both – and a Venus)

Hi Flyers,

I am planning to build a Venus II. The OS 120AX is suggested and also O.S.
120 Surpass 4C. Any thoughts from the group on choice. I'll be flying
Sportsman. My buddy goofy Bob Wilson leans toward the 120AX. I am somewhat
partial to 4 strokes. I like that V-8 sound and low end torque.
