I have the "ling cat" from avia-richmodel. It is extremely light weight as the bare airframe weighs about 12 oz. I am wanting the larger kee cat and have spoke with a vendor that is trying to get some in. Initial report was they are not set up for retracts despite the photos but then I was informed a while later that they were built with retracts. The specs are fairly similar between the avia-richmodel and nitroplanes as far as dimensions go. I am hoping the avia version comes out lighter than the listed weight as there is a 2 pound difference between the two. I never realized the nitro version had a glass fuse. Knowing how heavy chinese glass work is I am hoping the weights will be fairly close between the two. The AUW for the ling cat was 26 oz. on their site but I could easily see it coming in at 22 oz. or less without too much work so hopefully their other weight predictions prove to be a bit overstated as well. I would love to see some photos of this version after completion as well!
