Follow by 700 DFC/600 DFC's design, the 450 DFC flybarless rotor head system utilizes extreme low CG design, effectively reduces resistance during flight, increased flight responsiveness and precision, resulting in superior 3D performance and unimaginable flight speed with extremely attractive design.

Features:

● Extreme low CG and short main shaft design, dramatically reduces flight resistance, effectively improves Align's T-Rex 450 radio controlled helicopter 3D performance and speed.
● New style linkage rod design, complete assembly increases linkage rod rigidity, allowing the pitch slider (follower) to be omitted, resulting in a head assembly that is much simplified and rigid.
● Upgrading to the 450DFC rotor head assembly is extremely easy; just replace the head block included in the 450DFC kit, connect the 450DFC linkage assembly, and replace the main shaft with 450DFC main shaft. Existing swashplate is kept in the upgrade.
