Egodrift Tengu 4730EC Eclipse Shaft & Bearing Kit

Egodrift Tengu 4730EC Eclipse Shaft & Bearing Kit

Service your Egodrift Tengu 4730EC Eclipse motor or change its external shaft length to suit your installation. Choose the 6 × 35 mm or 6 × 55 mm kit according to your helicopter’s pinion and shaft-support requirements.

Choose Your Shaft Size

• 6 × 35 mm — EGO-11980: Standard-length option used by many modern 700 class helicopters, including suitable Goosky and XLPower installations.
• 6 × 55 mm — EGO-11986: Longer-shaft option for installations requiring additional reach, including suitable Mikado Logo, Align, Gaui, and scale mechanics.

Brand alone does not establish fitment. Confirm the required external shaft length, pinion position, and support-bearing engagement for your exact model.

Motor Compatibility

Designed for the Egodrift Tengu 4730EC Eclipse motor family. Select the shaft length required for your installation; motor Kv does not determine external shaft length.

Frequently Asked Questions

What does 6 × 35 mm or 6 × 55 mm mean?
The first number is the external shaft diameter. The second is the external shaft length.

Does changing shaft length change motor Kv?
No. Choose shaft length for physical installation requirements. The motor winding determines Kv.
