With our 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 20cc 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.

My Posts This: Topic  Forum		Sweeeet, I really like the no smoke and little vibration from a gasser. Maybe you should send me one so I can tell you what I really think!

It is essentially a 50NX head however, it's been upgraded. The feathering shaft is now a 7mm shaft so all bearings and dampeners have been changed as well.

Thanks.

What I was asking was not to upgrade later, but to upgrade the kit.
I would rather pay a little more money by buying the kit with the head and tail already upgraded, than to buy an extra head and tail unit for much more money.

Century used-to let buyers change Stock Parts in the kits for Upgraded Parts, but there was a flat fee of $25 to do so,, and of-course you would have to pay the price differences in the parts,,

but I don't know if Century is still doing this !! you will have to ask..
