The Zenoah G-45 steps you up to 45cc and 3.3 horsepower at 9,000rpm. It'll turn a Zinger 20 x 10 at about 7,200rmp. If you're craving "unlimited" performance, try it in your models instead of the G-38! Use an 18 x 8 or 20 x 10 propeller. Uses a gas/oil mixture of 32:1.
For giant scale pilots, the name Zenoah is synonymous with quality and performance. These engines are manufactured specifically for radio control applications to exacting tolerances which have made them the standard by which all others in their class are judged.
Zenoah engines offer unsurpassed reliability and performance—not to mention low-cost gasoline operation. And they're available in a variety of displacements to power just about any giant scale model you have in mind. They're built with quality features like CDI ignition systems, one-piece chromed cylinders, ball bearing supported crankshafts, Walbro™ carburetors and more.
They're also built to last, boasting an incredible 1000 hour plus operational life, more than most modelers will ever put on an engine.
Your Zenoah comes with everything you will need for installation such as a muffler, motor mount, and throttle linkage.
Note: the optional spring starter (ZEN4500) is recommended for easy starting.
