How much difference does it make in the drag, Ustik?  My son and I have duplicate planes (Gulfstream IIe, same weight, power, etc.) and like to fly them together.  His has retracts and at half throttle is easily able to catch mine with fixed gear.</p>

I can't imagine having a plane as nice as a Simla with fixed gear.  It may has well have cabanes and wires.</p>
