I had the enormous pleasure to test the Speedster from HAB in Sweden. It's developed by Tomas Krejci and its a 250 frame with a pusher. The idea is to give the quad a "plane" feeling and to fly fast with a low energy consumption.
Tomas has done some real cool inventions on hes remake of an 250 quad, might post some more text and pictures later...
I love to fly it, it's like a kick in the but when activating the pusher...
:-P
The frame has very good flight quality without pusher and it's possible to take of the pusher chassis easily.
It's mainly made to fly fast and low in open areas.
Tomas hasn't put the Speedster in his web shop yet, he needs a building manual, I might help him with that soon...
I didn't figure out how to insert photos in the text so I put some photos as attachment...
