Default RE: Blue Angel - Build

I started work on the wing with planning for the landing gear position. The position of the main gear in relationship to the projected aircraft center of gravity (CG) is really important to optimize ground handling and aircraft rotation on take off and landing. I like my aircraft to be fairly light on the nose gear but not so light that it is hard to taxi in cross winds or if you hit a bump on the tarmac the aircraft with rotate and the tail hits the ground. On the plans the main gear wheel strut angle is drawn very close to 90 degrees in relationship to the ground line making the wheel too close to the CG point for my liking. I’m not sure why it is drawn that way because by default the gear strut will be 90 degrees to the mounting area on the bottom of the wing making the gear strut angle back. This moves the wheel position back about 3/8” to an acceptable position.

By using a straight edge and a square you can project the rotation point that the CG will pass over the wheel contact point on the ground. See image below.
