Actually this is an Enya SS.30 BB engine.
So my choices are that Enya SS.30 BB, an OS .40 Stunt, Enya SS.40 S or the Enya SS.40 BB S or new J&B .40.
I an told to keep it light. All the Enya engines range from about 8 to 10 ounces without mufflers. The Fox .35 is about 7 oz.
So any of the engines should be light enough.
51 inch wing and about 550 squares.
Which engine do you all recommend out of my choices above?
All the engines except the K&B need prop extensions to fit properly on the Ares.
Actually I just laid the K&B .40 up against the plans and it fits perfectly without an extension. That sort of fixes my problem?
