Darcy,

welcome aboard.

Like Jeff mentions, the Bridi XLT and Escape are two ideal models that were designed for a RE exhaust 61 with pipe under the hood. The former is still being produced by Bluejay (link provided by Jeff) while the latter is a kit that from time to time can be obtained on auction sites. Two such Escapes recently were sold - the last for a great price of ~$100.

Other designs that would work well are the Kimbro Deception (also kitted by Bridi) and the MK Arrow. This last may also be available from someone on this forum who might have an extra one they'd be willing to part with (perhaps this is wishful thinking). MK kits are beautiful and go together like butter. Kimbro's Deception is very similar in construction to the other Bridi kits but may be a simpler build yet. Frankly, although kits do pop up from time to time, I'd recommend going with a short kit (RCFoamy here) and purchasing good quality balsa for the fuse and fin. The Deception, to my mind, might be the simplest of all to build by design - a beautiful model to boot and somwhat different in concept from the other designs of the era.

Pictures in reverse order: Deception, Arrow, Escape & XLT.

Happy building!

David.
