I just recently acquired a Trex 700N Flybar heli. I am converting it to flybarless. I would like to add the helical gearing from The DFC heli. Will this gearing work with the existing frames?

I have installed a 3gx flybarless head. And will be using the IKON2 controller, Align DS 615 servos on the cyclic and DS 655 on the tail. I will also be using the Align 90 engine that came with the heli. Presently I have the existing gear drive that came installed on the flybar head setup. Will this gearing work with the new flybarless setup or will i need to change it also? I have the 3gx manual and it does show different gearing then the flybarhead setup. Hopefully I haven't made this to confusing. All help is greatly appreciated.

No problems at all with the flybar gearing on flybar less. Head speed is head speed.
