ZCI's latest QD V2 metal gearbox. Has a number of improvments such as a channel for the trigger wire to sit so it doesn't get chewed by the pinion gear, front cylinder anti-stress radii together with a reinforced front end. Nice alternative to the E&C brand.
Features:
- 8mm Bearings
- Steel QD Spring Guide with bearing (2 lug)
- Philips head screws
- Reinforced material on stress points / radii
- Anti-shred wire channel for motor pinion
