I had a Twist 3D 40 back when they first came out, and put a Saito .82GK on it.
Was tons of fun to fly!

H9 stopped production of the Twist 3D 150 due most likely to poor sales.
H9 also axed their Ultra Stick 60 & 120 series as well.

I got my Twist 3D 150 last December, NIB for dirt cheap......plus 3 inches of dust NC.
You can still order the parts to assemble a Twist 3D 150, but it'll cost ya around $425.00 + shipping!<big ouch!>
