As to the engine, I think I'm going to sit tight with the Saito 1.00. No sense in switching to a new and as of yet unproven engine. That said, I'm sure the Webra would have been great. I think the MVVS .91 is probably a good choice too.

The other idea I've been toying with is a big electric power system. (Actually, this was my first choice.) The problem there is the small fortune in Lithium Polymer batteries that would be required.

As to the retracts, I had decided not to do retracts early on it the construction process.

Cheers,
