Dick's having fun with you.

Static balance, a 22.5 oz weight at 2 in is the same as 1.5 oz at 30. OK if you never fly it.

But the dynamic balance would be way off (weigh off??), since the moment of inertia is proportional to the distance squared. The moment of inertia (the total summed up) defines at what point of the roll axis the model will roll about when a force is applied. Further more, you could not just move weight up or down the design at one point and fix the problem. Think about spin balancers for tires. Weights go on both the inside and outside rim for best dynamic balance. So if servos are also mounted in the tail, their vertical position could be just as important as moving the battery up or down. Or the weight of the tires.

I would suggest that the difference between a good flying airplane and a great one is where the components are mounted. Fortunately most of us are not good enough pilots for it to matter, and no amount of transmitter mixing will fix these problems.
