Summary

There are a great deal of benefits to opting for gas, like cleaner operation and cheaper fuel. However Saito™ 4-stroke gas engines offer modelers more, particularly a few of the most remarkable power-to-weight ratios in their class. The brand-new FG-21 engine is no exception. Based on the groundbreaking Saito FG-20 engine, it packs 21cc of power into a 17cc case. Accompanying the extra displacement is the most recent carbohydrate innovation, upgraded exhaust valve seats and, naturally, the sweet 4-stroke sound Saito engines are famous for.
