Okay all you ARF guys. Here's your chance to give an old geezer your Honest opinion (operative word is honest) I am nearing completion of my fery first ARF. It is the Hangar 9 .60 size P-47, and I am deciding on the engine. I know for a fact that it will be an OS 4 stroke. The burning question here is which one. I have heard that the .91 is a good choice. My question is this... Would I be just as well off to use the 1.20 engine and practice throttle management ( I do know how to do this) since this model, by all accounts requires some extra ballast in the nose, and since I am a firm believer that weight should be functional (Larger heavier engine or Bigger more powerful batteries) or will the 1.20 engine shake the airframe to pieces? Give me your thoughts on this one please. I'll be good and not give any of my usual Smart A _ _ retorts. I promise
I am using a OS-91 FS in my H9 .60 P-47. It balanced perfectly with no ballast, however I do have an onboard glow driver with a C-cell battery mounted just behind the firewall. The plane is a joy to fly with plenty of reserve power. Either the OS-91 or 120 will make your Jug a terrific flyer.
