OS 91 FX suitability

[Stavros Ioannidis]

Thank you Matt K. and everyone else who answered to my letter.
I am in Greece and since my last pattern plane is allready ten years old (Conquet IV)and a two meter plane is too much (and expensive) for our local competition (and F3A practicing), I choosed the Swallow with OS 91 FX but my concern is the bad rumors  that I heard about the OS 91 FX (needle valve assembly, ABN plating etc) and I wonder if a 4C is more suitable for my plane.

  Yia sou Stavre. 

  The OS 91FX will work fine in this application. My friend Nat Penton uses the engine on his 8+ pound models, and also has adapted the Perry pump on the backplate. His pipe length is longish by many standards but it needs to be since he turns a 17x10N 2 blade or the small 4 blade apc props (13.5x11 4 blade)

  Are you in Greece or US?

      I want to haul a Swallow 90 for using it in aerobatics. Is the OS 91 FX a reliable engine or there is a better choice ? Any suggestions ? Thank you in advance.
