I just bought the Spot On from a local hobby shop and after I got it home I noticed it was the A249. Not the the a249R???? []

Were there some issues with the original.? It obviously must have been in the store for over a year??? I noticed on post #44 that the wing root is different and the wing attachment is different. On the "R" does the wing bolt on to the fuselage and then the belly pan is attached?? That's probably a better arrangement than gluing it to the wing, although, I could live with that.

Normally when a company upgrades a model it is to correct problems with the original?? Does the 249R fly better??? Also were there other problems?

I plan to put an O.S. 55 with a pitts muffler on my plane.

Rally, my question is...SHOULD I RETURN THE A249 TO THE STORE AND ORDER THE A249R????[&o]

Thanks.
