I ran into a slight speed bump.

Someone gave = me a Velocity RG. (Yes =E2=80=A6. I really mean he gave it to me. N5325)=C2= =A0It=E2=80=99s been sitting in a hangar for the past 11 years due to some = rather minor issues.

The end result will be no more renting airplanes and at= the same time building canard time for the insurance underwriters.

In the meantime I am getting better with the 3D CAD softw= are.

I'll be moving on to the air-box (cool side intake) once this is don= e.
