RE: Tiger 60 Kit Balance Point ??
The reason there is a span of the measurement pont is because of the variations in the build (or in the case of an ARF the assembly) process. They (Goldberg) has on idea where you plan on putting your battery, nor what kind of servos you intend to use. They all weigh in at different weights and can all cause a shift in the actual CG.
Measure it using any method you wish, your fingers or with a CG device, then set it for wher the nose will slightly dip at some point within the CG limits. Then fly it. After you fly, you can then adjust the CG as necessary by shifting the battey forward or aft, or by adding weight to the nose or removing it as necessary.
In other words, there is no real way to answer your question with a definitive "4 1/2 inches" or some other measurement with accuracy. It's a range that will get you in the air successfully, then you make adjustments as you see fit after that.
Hope this helps.
