Check the C.G. (Center of Gravity)
When balancing your model, adjust the motor battery as necessary so the model is level or slightly nose down.
This is the correct balance point for your model. After the first flights, the CG position can be adjusted for your
personal preference.
1. The recommended Center of Gravity (CG) location for your model is (80-85mm) forward from the leading
edge of the main wing (as shown) with the battery pack installed. Mark the location of the CG on top of the
wing.
2. When balancing your model, support the plane at the marks made on the bottom of the main wing with your
fingers or a commercially available balancing stand. This is the correct balance point for your model. Make sure
the model is assembled and ready for flight before balancing.
