500DFC Main Rotor Head Upgrade Kit...
This is an optional Align 500DFC Main Rotor Head Upgrade Set, and is meant for use with the Align T-Rex 500E and 500E Pro helicopters. Followed by the Align 700 DFC?s style, the 500 DFC flybarless rotor head system uses an extremely low CG style which effectively reduces resistance during flight and increases flight responsiveness and accuracy. All of this results in remarkable 3D performance and an unimaginable flight speed with an extremely attractive design.
Features:
Severe low CG and brief main shaft style, significantly reduces flight resistance, effectively enhances T-Rex 500?s 3D performance and speed.
Two part removable main blade grips for ease of upkeep and assembly.
Brand-new style linkage rod style, complete assembly increases linkage rod rigidness, allowing the pitch slider (follower) to be omitted, resulting in a head assembly that is much simplified and stiff.
Updating to the 500DFC rotor head assembly is very easy; simply change the head block included in the 500DFC package, change the blade grip pitch lever with the brand-new 500DFC lever, connect the 500DFC linkage assembly, and change the main shaft with 500DFC main shaft. Existing swashplate and newer main rotor grips are kept in the upgrade.
The damper rubbers are produced using POM material, smooth surface area, with remarkable anti-wear attribute.
Appropriate for T-REX 500 flybarless system.
