We present to you our new project, the SF-33. This is a model of a German motor glider from 1970. Our model has a wingspan of 5,6m. The model is made entirely of plywood and balsa, and features a laminate engine fairing, a predominantly air-suspended carriage, two wing side wheels, and a tail wheel. The rudder fairing is also made of laminate. The estimated flight weight is 12-13 kg. It can be powered by either an electric or combustion engine. We installed an electric motor powered by a 12s and a 20x8 propeller. The model can be powered by an 8-10s LiPo battery, and the combustion engine can be from 35cc.

The model will be available for sale soon, but you can already pre-order the KIT (basic set, cowl, cabins, rudder cover, complete wing wheels, amortized main wheel, and other accessories necessary for construction). The ARF version is available for pre-order with a delivery date of August 2026.
