250DFC Main Rotor Head Upgrade Set (H25119T)

DFC main rotor head upgrade set for Align T-Rex 250 radio controlled helicopter.

Preceded by 700 DFC/600 DFC's design, the 250 DFC flybarless rotor head system offers extreme low CG design, wich significantly reduces resistance during flight, increasing flight responsiveness and precision, resulting in superior 3D performance and unimaginable flight speed with extremely attractive design.

● Extreme low CG and short main shaft design, dramatically reduces flight resistance, effectively improves T-Rex 250’s 3D performance and speed.
● New style linkage rod design: this 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 250DFC rotor head assembly is extremely easy; just replace the head block included in the 250DFC kit, connect the 250DFC linkage assembly, and replace the main shaft with 250DFC main shaft. Existing swashplate is kept in the upgrade.
● Suitable for all T-REX 250 flybarless system.
