14)	Take-off with some engines out of service: OK

-----------------------------------------------------------------------

SECTION D: 	NOTES/COMMENTS:

1)	This is an FS98  version of the aircraft

2)	Watch out for a stall. This aircraft seems to "fall out of the 
	sky just after the Stall Horn sounds. 

3)	Doesn't need much runway to take-off or land. This mirrors
	the real a/c according to the included docs.

4)	Short range. The range, as tested, is half the range of the real 
	aircraft. Mixture control set to "Rich"!

5)	In manual turns, if the bank is more than 30° then the a/c begins
	to sideslip.

6)	The figure for overspeed was only obtained in a steep dive! Try
	not to tear the wings off!!

7)	When an engine fails at rotation speed and flaps are used then
	it is unlikely that the a/c will climb. More likely to stall
	and crash.

	Take-off clean and you have a better chance. Climb ability is
	about 100 - 200 fpm with full power on the remaining engine.
