The Saito FG-40 is supplied with a CE approved electronic ignition system and a purpose made aluminium engine mount. The carburettor employs a diaphragm pump for reliable fuel feed in any attitude - even the wildest of 3D stunts! This also means that it is not sensitive to the position of the fuel tank, which allows the tank to be positioned to maximise the CG position. You can use forecourt quality petrol mixed in a ratio of 20-30:1 petrol to oil.
