Century Radikal - Hawk - 50NX - Predator > Hawk Pro constant tail drive

My Posts This: Topic  Forum		I just purchased the Hawk Pro constant tail drive so that I could practice auto rotations without the heli weather vanning. The upgrade came in the mail today. True to Century standards, the instructions are lacking to say the least. I have read the quarter page installation instructions and well, I am confused. Does any one know of a link? Or does anyone have any build photos?

My Posts This: Topic  Forum		Zaneman007,

I don't have any build photos, but the installation is pretty straight foward. Replace the existing counter shaft and plastic gear with the new one. The new plastic gear does need to be installed on the new autorotation clutch. Then remove the main gear, and remove the autorotation clutch from the main gear. Install the aluminum main gear hub, and reinstall the main gear with the new hub.

I'd be happy to try and answer and specific questions you may have.

My Posts This: Topic  Forum		All this kit does is move the autorotation bearing from the main shaft to the counter gear shaft. I have unstalled this upgrade on a Falcon, and was impressed how easy it was to install (more impressed than the performance). With the kit installed, the machine WILL bleed off head speed a lot faster than before!

My Posts This: Topic  Forum		Yep, driving the tail rotor during an auto on any heli certainly does bleed off head speed faster as it takes more energy to drive a tail rotor (even at 0 pitch) then most realize. A lot less on a shaft drive then a belt drive, but still a noticeable amount.

My Raven 30 has the CTD unit installed while my Hawk Pro is stock. Using the same rotor blades on each there is noticeably more reserve at the bottom with the Hawk.

But I am an addict for piouetting autos, and there is still more then enough reserve with the CTD unit so I have much more fun autoing the Raven 30 with the CTD unit.
