Seemefly this is not a 3D plane. Yes it would KE but also would a P-51, and many other trainer out there. I agree with Cyclic Hardover a Hanger 9 Ultra Stick is a great 2nd plane. You can fly it sport style or 3d style (if you build it right). I am not a big fan of the Great Plane "You Can Do", but this also would be a great choice for a 2nd plane if you want 3d. With the basic electric setup on the sundowner is the same as the basic glow setup for the Sundowner, mean it will not changed the way it flys. The difference will be glow or electric.
