[NSRCA-discussion] Venus Engine Question

[John Pavlick]

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.

  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.
