Hi,
I just completed built the Seagull 300S and have a question about the balance point I had .91 Magnum 4 stroke in it and followed the instructions said 4 cm from the leading edge to balance but tail still heavy even i moved the battery, RX next to gas tank. 4 cm is little over 1.5 inch. I never see the balance point that close to the leading edge. I wonder that 4 cm at the wing tip. Please let me know what is correct point.

Thanks, Tom
