This is the Align Main Rotor Head Upgrade Set. This Main Rotor Head Upgrade Set is blue colored and compatible with the Align T-Rex 450DFC, 450 PRO, 450 SPORT, and the 450 V2.Features:
- Extreme low CG and short main shaft design, dramatically reduces flight resistance, effectively improves T-Rex 450’s 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.
