RE: ARF Ultimate Bipe, .40, Does this Exist?
I like my World Models Ultimate 30. Still $150. I've had mine about 3 years. There are minor issues with it, like the gear is soft and the upper wing mounting should be reinforced before flying. Otherwise I love it.
Mine has a .52 Magnum 4stroke, and has lots of vertical. I don't hover it, but I can hang it on the prop for several seconds. I think the Magnum .61 4stroke is the same size as the .52, might be 3D capable.
Just my two cents worth. Good luck,
