Thanks Lou,
So to increase roll rate on the 707 would you have to set the spoilers or would they kick in automatically based on your commands? . I'll try a roll using spoilers and see if that helps performance. The 143kts ( and the formula you provided)  makes landing a lot easier
As you mentioned, the boost pumps on the controls really make the 727 much more concise and responsive in every aspect of flight.
I've never used flaps 50 as I read in the manual this was used for shorter or wet runways when less distance was needed. Think I'll rely  of the advice of a real 707 pilot such as yourself. Thank so much for all your help.
