This is the Saito Engines FG-21 (1.26) 4-Stroke Gas Engine. There are a lot of advantages to going with gas, like cleaner operation and cheaper fuel. But Saito 4-stroke gas engines give modelers more; namely some of the most impressive power-to-weight ratios in their class and the FG-21 is no exception. Based on the groundbreaking Saito FG-20, it packs 21ccs 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.

Features:

  • Gasoline engine lowers operating costs as much as 90%
  • Latest carb technology makes for easier tuning and operating
  • 21cc displacement in a 17cc case
  • New valve seat design
  • New, smaller magnetic ignition system fits into tighter cowl installations
