In order to meet 200lb FF, a bare engine, = say long block, should be under 100lb. My 12A based single is 90lb = giving a FF of 170lb. The 701 probabely will only require maybe 50hp at = cruise, and the utilization of every hp over and above that depends very = much on a proper prop dimensioning and setting. Especially on take off = distance, the heavier, stronger engine does not give you an advatage, = generally speaking. It mostly makes you climb better at higher airspeed. I have a friend with an AVID running a Rotax 582 with 65hp. His take off = distance is essentially the same as mine with 100hp, however, my = airplane is 15-20% heavier.=20 FWIW.
