I just finished building a Bobcat 50 with retracts (see pic). I am now setting the CG and finding it very nose heavy using the 260mm balance point. Since the fuel tank is located in the rear of this plane, I am wondering if I should balanced with the tank at least 1/2 full. I currently have the receiver battery located in the forward compartment as shown in the instructions, but will most likely need to move it back to the rear compartment. Any suggestions will be appreciated!
