Its a Kalt GS Baron. I have 2 of them in pod and boom form. The engine is a KG22 2stroke petrol, and some parts are interchangable with Zenoah. The main frames look similar to the 60 nitro version but the only difference is the engine mounting holes.

I have parts lists, drawings and brochures etc. If you require copies let me know.

Kalt also produced scale fuselages of the Jetranger, Longranger, Ecureuil, Cobra 500, Bell 222 and the Hughes 500 but its difficult to identify yours.
