RE: From Ember 2 to Piper or Carbon?
Yep, Champ all the way. The Champ can still fly in a smaller area, although it needs a bit more to fly in than Ember I think. More like a baseball field or park. The Champ is going to fly faster too. The Champ is a 3 channel plane like the Ember I think, just faster. The Carbon Cub is a true 4 channel plane and would be a pretty big step up from the Ember. It has virtually no dihedral in the wings so it doesn't glide quite as well on a dead stick as the Champ. Maybe after the Champ you might want to go to a larger plane.
