I had only contacted them about the ultimate as that is the only one I would be interested in. I had several different answers to the dimensions of the plane. And not getting an answer to when any may be available or if they will at all. It may have just been the language barrier but, from what I gathered it was close to being a nitro ultimate with different hardware. I hope I'm wrong because I would eat the tires off it to get one that is truely a 30cc ultimate and not just a 1.20 size that I could cram a 30-40cc engine into. Which I have been contemplating as is. As of right now I have two planes on the bench waiting for the yd-a 38 to come out. 1/4 Super Decathlon and the 1/4 Kangke Waco.
