Rusty,

do you have the plans for it? Maybe, being an ARC of sorts, the plans didn't come with it?

I have the kit (not finished) and I just recently scanned the plans (see attached). As Arch and Mike say, it was designed for a RE 60 with pipe under the belly. You'll see this from the plans (which could use a little more contrast...)

BTW, please send me a PM with cost and location for the twin! I assume it is at the same ARC stage as yours?

David.

Oops, forgot the attachment. Here is.
