Matt,
There is a "pico stick" trim scheme for the BLT in G2 on the swap site at
www.realflight.com/swap.
You can not create a plane from scratch in G2, but can change the settings on any of the base planes. Changing the settings modifies the flight charadteristics, but not the visual look of the plane. So, you can make the plane fly how you want, but it will look the same.
Oh yeah, you can change the trime scheme but not the shape of the plane.
