Century® Radikal G20 Gas Powered R/C Helicopter Kits
September 2, 2020 – 02:23 pm

With the experience and knowledge from producing aerobatic and trouble free gasoline powered helicopters, Century Helicopter Products is proud to announce the ALL NEW Radikal G20! This highly anticipated helicopter (the smaller sibling of the Predator gasser) is capable of smooth F3C style flight yet has the power and agility for 3D aerobatics. Designed from the ground up with the latest manufacturing framework, we're proud to offer the latest generation of technologies which has been incorporated to produce a G10 or Carbon Fiber framed helicopter being powered by the new Zenoah 20cc gasoline engine. With its high torque and its relatively low speed, the Zenoah offers smooth, vibration free operation. The Radikal G20 is capable of being top started with a 6mm hex style starter extension. We also offer a removable style pull-start option. With the advent of gas powered helicopters, expected long flight times are here to stay at the expense of merely pennies to fly. The gas powered engine produces absolutely no smoke offering endless capabilities for aerial photography/videography as well as scale fuselage applications.
