Hi Doc,

I ended up with a .030" shim under the front stab screws........I also had the model balanced right on the spar tube, without the outer pannels mounted,as suggested by Alan.
It took 5.75 ounces of lead in the very front of the nose (above the landing gear mount) to get it to balance that way........ but I would always start with it balanced there for the frist flights.

I have removed all the nose weight and added 1.5 ounces to the tail, There has been no need to change the stab incidense any further, and after 52 flights I am very pleased with how the model performs......not that it wasn't great all along, it's just very comfortable for me now.

I also have 30% down elevator mix ( about 3/16" of down) with 45 degrees of flap....and the model maintains level flight with the flaps down and slows down nicely.

Alan's Sprint design flies as well as any model I have flown in the 50 years I've been flying R/C........Do it like he says and you'll be a happy jet pilot.

Paul
