Rob, Ed,

 

I=B4v a = LNC2=A0 320 with IO-320, slow build kit, small elevator, no wing = extensions, MT 3-blade prop.

Following = remarks are my personal feeling/experience! It might be different with = other kit configuration:

1.       = I limited my flaps to -5=B0 = because:

-          = a transit from 0=B0 to negative flap position = will have significant influence to the elevator = trim

-          = I did some performance tests many years ago and = found -7=B0 will not show higher cruise speed than -5=B0 = =A0

-          = you need more clearance gap between upper wing = skin an flap

2.       = I limited my flaps down position to +35=B0 = because:

-          = More down degrees will not produce higher lift = but dramatically more drag

-          = More than 35=B0 will it more difficult to have a = nice flair behavior

-          = More than 35=B0 will produce higher loads to the = flaps

 

You see, I = did not=A0 use the manual recommended parameters =

Hope this remarks are usefull for = you.

 

Best = regards
