Steve,
You can see how I did my nose weight. I haven't run the numbers in the current configuration But I'm at least 1/2" back from the recommended position. for your initial testing the factory spec is a good place to start. Just be prepared to remove weight as you get a bit of time on the plane. Gear up or down doesn't seem very critical but if you do it gear down then you can be certain of the CG during the takeoff and land phase. I suspect that when it's all sorted out I'll be 3/4" to 1" back from that point. The elevator does become more effective as the CG moves aft so elevator throw can be reduced. I use Expo to soften inputs around center stick.
I am using all the Aileron throw and with expo dring high speed flight I just leave it a hi rate. Maybe for some scale maneuvers I might try lower throws to avoid overcontrol.
I run triple rates which is common on most higher end radios. Another FW operator commented that he too doesn't need much elevator throw to fly and land either.
Ill try and get throws for you in a few days.
