 Two engines were intended to be fitted to the welded steel tube engine nacelles but the prototype was fitted with two Walter Major 6 engines, with instruments fitted to the inner sides of the nacelles where they were clearly visible to the flight crew.Two fuel tanks of each were housed in the wings with oil tanks in the engine nacelles.Flight trials were relatively successful but no orders were forthcoming, meanwhile several improvements were carried out to the nose, which was elaongated, and at a later stage a twin tail was fitted in lieu of the original single tail.
