RE: FAST 3d plane
Fliton has the Inspire 90,I would not do many full throttle passes,but I bet its much faster than the Twist.
The Showtime is also alot faster and is 3D capable.
The showtime 90 has had some unhappy owners,it requires patience in set up and fair bit of experience to fly well,but it maybe what you are looking for.I would say the 90 is just enough for it,while others say the 120 2 stroke is borderline,I've only seen them with 4 strokes.But this hybrid Pattern/3D shape is what you are looking for.
