I'd rather move the servos. The tail is pretty big as it is. I'd hate to tempt flutter any more than necessary. I don't know the math, but the two tail servos could be moved 8 to 9 inches aft. That would place them just behind F5 and the elevator servo could be high enough to keep the pull-pull set up. That would take some of the lead away. I do not think it would eliminate it all together, so it's probably not worth the hastle. The stock servo locations are fairly aft of the CG to start with. If someone was to do it, be sure you cut servo wire holes into F5 before sheeting that area, as that former is solid. All the others have some hole that a set of wires could go through. Also, I think you could double the size of this tail and probably wouldn't add more than an ounce. The stick framework is very light.
