HK-550TT Flybarless 3D Torque-Tube Electric Helicopter Kit (US Warehouse)

Finally, a 550 class flybarless helicopter kit that won't break the bank! Modeled on the famous and proven T-Rex 550, the HK550TT FBL will push your 3D skills to their limits.

This 550 size helicopter offers an excellent power-to-weight ratio that makes for stellar 3D performance. It utilizes the same power system as a 600/.50 size electric heli, but is lighter and spinning smaller blades, thus offering much higher performance and efficiency. Also featuring a flybarless rotor head and torque-tube driven tail, this machine is capable of handling whatever hardcore aerobatics you choose to throw at it!

With its black anodized CNC alloy head & tail unit and beautifully finished carbon fiber frame, the HK550TT FBL is as nice to look at as it is to fly. This kit has just about all the alloy upgrade parts you could want already installed such as battery mount plate, tail servo mount, tail pushrod guides, anti-rotation bracket base and main bearing blocks. There are very few plastic parts anywhere on this heli! 

The HK550TT FBL uses high quality tail bearings and tight tolerances to ensure no slop in the tail assembly and locked-in tail performance for the most extreme of 3D flying.

This heli comes 90% pre-assembled so you can be in the air in no time. Just complete the final assembly,  add your favorite main blades, install your own electronics and your ready to fly!

Wow. i very happy i did not buy the align kit.It is great quality , i heard all the stories about clones and was a bit worried until it came,and was able to really inspect it myself. the build went great with no issues other than the broken canopy witch i kinda expected ,but my heli is as good as an align and i still have the 396.55 difference in the cost i was going to pay for the align. great price great heli . thanks hobbyking.
