I've flown the Sig SE, the UcanDo, the Twist, and the FuntanaX. The Sig SE is a good plane, but their knife edge (KE) performance is lack luster, which was one of the criteria. Yeah, they will hold a KE, sort of, not really, kind of like the twist. The UcanDo however will hold KE all flight long if you want. Most the funfly plane types like the sig SE and twist are capable of fast loops and rolls, but they can't snap or spin properly, which leaves out entire groups of 3D moves, so I have a bit of an issue considering them a 3D plane. The UcanDo also has 3D issues, but it is very capable of KE, so out of the list, it got my vote since it met the most of the criteria the poster listed. However, with the mention of a new plane option, i.e. the FuntanaX, I change my vote from UcanDo to FuntanaX. The FuntanaX will snap/spin well, hold KE, and can handle moderate speed.
