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.
Spec. Shaft size: 5mm Feathering Shaft: 4mm Kit includes all parts shown in part image. Rotor head is required.
What cant fit there? you need to remove flybar and replace sliding part on main shaft with it's arms. It's fit mainshaft ok.. Then you need to replace main rotor blades grips with it's shaft.. BTW I didn't find any diff in blades shaft... looks exactly the same... well.. last thing replace rods.. The only thing which MAY not fit is length of blades grip shaft...but probably you can reuse existing one
i think it's pretty awesome for an upgrade for just under $10, i already have a T-bar, but am quite skeptic to use it on my Rexy 600, but will try to hook it up to the HK450. Thanks HK for the cheap and fair prices.
Nice quality and finishing. Initially i thought that the quality wont be so good at that price but guess i was wrong. Haven't actually tested these on my heli so can't say anything about how well they would perform.
ordered this one after Ive ordered the other FBL head HK sells here which came without the extended arms. this way it's cheaper as ordering Align arms only!

j ai reperce axe rotor et hub 450V2 pour mettre une vis de 3mm afin d'avoir un blocage sans jeu.Sur le 2eme trou des pieds de pales, les grandes bielettes touches la mecanique lorsque plusieurs commandes sont activees, sur le 3eme, les bielettes ne touchent plus mais c'est les bras de mixages qui forcent de trop, en clair je mets que 3 toiles car la position idale serait entre le 2eme et 3eme trou.Je suis actuellement sur le 2eme trou avec des debattements reduits a cause des problemes cite ci-dessus.il faudrait retarauder entre le 2eme et 3eme trou du pied de pales. Hobbycity a de grandes idees mais n'essaye pas ses produits..Dommage L autre solution serait de rduire l epaisseur des bras de mixages
