I am flight testing my model 7,  I have an older kit as the elevator

has trim tabs.

I have been adjusting the horz leading edge down to get more nose up trim

but am almost out of adjustment.  full aft (nose up ) trim gives me a hands off stick approach speed of 75 mph.



Like to know what others are doing.

David,

	75 sounds a bit too fast, but then I do not have a neutral stick.

With full flaps and engine at idle, I have between 55 and 60 mph approach.

With full nose up trim and full flaps and engine at idle, you shouldn't be

landing any faster than 65mph max. Hold a little back pressure and slow that

bird down to 60 or less. You're still well above the stall speed.

During the 40 hr test period my test pilot reported the same thing.  

We removed the front bolt and lowered the hort. stab to where it  

touched the fuselage, then drilled a new hole at that location.
