RE: Scale Aerobatic Second Plane
If you are absolutely going to get an Extra, Edge, Cap, etc. then get a profile version of one. The profiles will still do all the 3D and extreme aerobatics, but handle more easily for someone who has only flown a trainer, as long as the control throws are left fairly low at first. I would go for an OMP of Morris. But it is probably the best idea for you to get a Four Star or Stick type plane first.
