Ultimate is the one with the ultra light C50.

Even the stock kit flies pretty slow and ir does feel like a bigger plane...thats why I have been so impressed with it and pushed on to production... Ive never had anything like it. Im steadily selling off my other models now because I dont fly em... just trying not to buy new ones to fill the gaps ! That said Ive now got a Madness 2 to put together...first appearances tell me its better than the Flip and the Madness 1.... And Im not supposed to be into Fun Fly anymore !

Ho Hum..
