Product Description

There are a lot of advantages to going with Petrol, like cleaner operation and cheaper fuel. But Saito 4-stroke Petrol engines give modelers more; namely some of the most impressive power-to-weight ratios in their class. The new FG-21 is no exception. Based on the groundbreaking Saito FG-20, it packs 21cc's of power into a 17cc case. Accompanying the extra displacement is the latest carb technology, updated exhaust valve seats and, of course, the sweet 4-stroke sound Saito engines are famous for.

The carburettor features a diaphragm pump that is very tolerant of differences in fuel levels, making it unfussy regarding fuel tank positioning. This means you can now fit the tank to give the best centre of gravity for the airframe rather than worrying about the best position to keep the engine running. The pump also allows for smooth running during advanced aerobatic manoeuvres.
