HK450 Flybarless Head upgrade (T-rex compatible)

We thought existing flybarless head upgrades were too expensive.
So what did we do? We made our own!
The HobbyKing 450 Flybarless Head upgrade system will bolt straight on to most T-Rex 450 or compatible helis. Just take note of your shaft diameter.
All parts are precision machined for a good fit.
Why so cheap you ask? Because we make it ourselves!

You will need a flybarless electronic stabalisation system, like the one shown in our related products at the bottom of this listing.
