Hopefully Dick will clarify this, but I think the Runabout is the predecessor to the Runaround. I'm betting it has a wood fuselage, too. The original Runaround was published in Model Builder (if memory serves.. ) and looked like a Zlinn 526 relative.
I think it is safe to say that if Dick designed it, the plane will fly well. I LOVED my Runarounds.
Can you post a photo of the kit? Is there a picture of the completed model in the instructions?
