Southern Touch9 has the right idea. There is no reason you can't go ahead and buy another plane to fly while learning on the Spad. Being able to get the feel for a new plane will only benefit you in the long run. If you have built up enough confindence to try something with the new plane, go for it. If you still have doubts, stay on the Spad a bit longer. Just remember, the new 3D plane will be able to do more than just harriers, hovering, and flat spins. Try some waterfalls, blenders, walls, inverted harriers (high) with your new plane. I never once stated that a new 3D plane couldn't be bought and flown, I simply didn't reccomend it to learn low maneuvers with. An O.S. .46 FX with a 12X4 prop is more than enough to power a profile or Spad.
