I did the same thing you did. However, I find that the Creek planes fly better a little tail heavy. The instruction calls for 30% balance, but I think it flies better at 33%. The Creek planes have thicker airfoil at the tip (13%) than the root (12%), so it will not tip stall too bad. At 33% CG balance, it will not stall in a moderate speed turn; it will only stall when it's too slow on the landing flare, like 10 mph; even then, it's a gentle stall that's recoverable in 5 ft vertically.

You can start by having the elevator servos up front, and gradually add tail weight to see how the plane responds. If it flies fine at the aft balance, then move the servos to the back.

Yes, I hated it when the elevator servos were up front. I had 2" x 0.5" cut out for the pushrod because they move so dang much at the passthrough.
