Hey Guys,
I converted my FA-125A Saito to gas one year ago.
The oil gas mixture I used is 1:25 (synthetic oil).
It has burned about 20 litres gas now, and there was a lot of carbon in exhaust pipe and outlet valve.
The ignition is a "Runtronic mini" it has a weight of 50g + 1 Lipo cell 800mAh.
The engine mount was a square block of aluminium which I milled down to 58g.
It replaces the rear cover of the crankcase.
Fuel tank is 150ml. All over wheigt of plane is 3.9Kg.
