I'm not seeing and further drawings in your gallery. Either that or I'm not getting access to them. Just the pictures of your calculations.

If this thread related to your glider project then I'd have to say that the fuselage looks far too short unless you're intending to install an electric motor up front. Also the fuselage tail length needs to be determined in a way that relates to the tail volume coefficient. Taken in isolation like this all I can say is that unless there's a big lump of weight up front on that first bulkhead then your model's nose is too short.

Keep in mind too that for reynolds number scale reasons it is always best to use a horizontal tail surface that has a smaller aspect ratio than the wing has. A good round number is that the tail should be about 2/3 and certainly no more than 3/4 the wing's aspect ratio. The apparent small tail chord would seem to indicate that you may not be going down that path. The reason for doing it that way is to help avoid the tail stalling out and losing it's influence on the wing.
