Larry:

With a pair of hot 46 engines it will be a rocket ship. I'm intending to use a pair of K&B Q40 engines, I will not be surprised if it hits 120 or so in level flight.

It's not what I would suggest as a first twin, but if you are comfortable with a hot single engined stick you'll be OK - just watch for an engine going out.

Even so, this one looks like it wont be too bad on one engine, but like any twin you can get in trouble quickly.

The Twin-Air 45 is still my recommended first twin.

Bill.
