[NSRCA-discussion] C'ARF Integral - Mixing secret?

[Woodward, Jim R (US SSA)]

Thanks Bryan,

This plane was so "mixed" up (pun intended) I'll offer this advice to the owner and ask for a report back after this weekend. Jim

Jim ,
The airplane "Is" set up with the c/g too far back, that`s all there is to it. 
I`ve fixed way to many of these ,,for the same problem.
Add inc, to the main wing, move the c/g forward to 25% mac .
All these mixes will disappear up elevator with rudder, rudder low throttle , wing dips on hard pull outs ect airplane requiring aileron differential ECT.
Trust me, I fix um all the time.:)

You would be surprised to know how far back you can fly the cg and it seem ok !

Control surfaces were indexed close enough.  Wings and stabs were nice and tight against the fuselage.  Positive loop tracking, and square loop tracking, with constant throttle position, was very good.  Outside loop tracking needed a SLIGHT amount of rudder (certainly no biggy).  It was the speed/throttle dependant.  Rudder trimmed for uplines, looked very normal and straight down the line.
