Did you mean the Me 263 or the Me 163?
Mike (x2) has pointed out the 1/48 Me 263 from CM which was a continuation of the Me 163 design with a longer fusealge for more fuel, a two stage motor to allow a cruising speed and most importantly... landing gear. I've built the Huma 1/72 Me 263 and I understand that Special hobby has also released a 1/72 Me 263. I do not believe there is a 1/32 version.
Hasegawa is about to re-release a 1/32 kit of the Me 163. In 1/48 scale dragon models has the Me 163 and I believe there was an Eduard model and a Revell kit as well in that scale.
