[NSRCA-discussion] Fw: [NVRC-List] Venus 2 with OS 120Ax

[Ron Lockhart]

Hi Randy,

I understand the Venus has options for servos in tail or in wing bay.  Which location did you use?   
How did you get correct balance with the OS 1.20 and stock muffler?
Thanks,
Ron Lockhart

  Well I got 4 flights on the Venus 2 in-between the squalls this afternoon.  That makes for 3 days of flying and the basic trimming and engine break in is complete.

  This model is at 8 1/4 pounds with fut 9202 servos and 1500 NiCad pack.  It should be not too hard to get it down to 8 pounds.  This engine is more than enough at this weight.  It is swinging a 15X11 APC with great gusto.  I had 30 MPH winds for one flight today and had no problem.  One of the local IMAC guys called it overpowered; but I aint sure what that means.  I am getting lots of practice moving the left stick forward and back.

  If you have someone looking to try pattern; go ahead and suggest this model.  With a OS91FX or Saito 100/125 this would be a nice starter plane.  It is a very simple plane.  Really no harder to build than a typical 40/60 sized ARF with two wing servos.  The provided 16oz fuel tanks is probably too large.  I can fly intermediate twice and have about 4 oz left.  I am thinking of going for a 10 or 12 oz tank.  With a YS110 or OS120AX it will fly anything in the pattern book.

  As for the OS120AX, I really like this engine.  It will handle a APC 16X10 and the engine is easy to adjust.  The book does call for a five flight break-in period, which seemed about right.  I started leaning on the sixth flight and it started singing.  I am thinking of designing a Model around this engine.  It should handle anything up to around 9 pounds on the stock muffler.  Maybe the Insight if I can keep it light enough, or the CA epilison 120.
