What kind of glider is this?
I bought this glider at a swap meet today. One person said it was a Cermark, but I couldnt identify it as that using Google images. I have no idea what it is, it has about an 8 foot wingspan, composite fuselage, full flying horizontal stab. Heres a few pictures.I would like to make it a powered glider via cut the nose and install a motor or using a pod. Any help greatly appreciated.
Thanks, Denny

First it looks like a nice sailplane.
I think you may have an original design. Flaps on a poly is uncommon, and the way the stabs are too broad for the fin makes me think someone bought a fuse and either put a set of wings on it he had laying around or scratched a set up for it.
To make it electric I'd put two flap servos in the wing to open up the fuse some. I wouldn't worry about the weight, most 80's sailplanes had lift to burn, the extra weight will help it penatrate. I put a electric motor into mu scratch-built sailplane it didn't add much weight and it still floats like a butterfly.

Thanks for your input. I have looked this over closely and I seriously doubt it a one off. I am sure tis a manufactured item,,just not sure who marketed it.
Thanks, Denny

RE: What kind of glider is this?
Cermark is a maker that produced a variety of gliders. So calling it simply a "Cermark" is only helpful to a limited extent.
And I have to agree with Soarrich that the fit of the stabilators to the fuselage makes it look a bit like the fuselage may be a replacement for an earlier busted one. One way to tell would be to look at how well the wings mate to the root stubs on the fuselage. If they are an equally poor match either to chord length or to airfoil shape then it supports the idea that the fuselage was a replacement for something previous. Also it was odd to find flaps on poly models. So again it suggest that it may be someone's custom made model.
