The PAP Precision 'Contra Killer' PCK F3A Drive is a 4-blade low RPM power system with a constant speed, linear feel and excellent braking. Owners of the 2-blade Precision F3A Drive can upgrade to the PCK with a conversion kit, just ask us about it!
This system uses 4 folding blades borrowed from the Adverrun contra power system (with permission).
The slower RPM setup makes this feel like, and brake like, a contra system without the added complexity and noise. This drive is super quiet!
The drive comes pre-packaged with a lower KV EGODRIFT motor, bigger pinion pulley, a new CNC machined 4 blade prop hub and a set of folding blades to suit. It will also come with a firewall, installation jig and rear support ears.
PAP anodises the alloy parts in house so custom colors are possible.
The intention is to use Falcon spinners with a custom cut cone, or modify your own 2 blade spinner to suit the PCK F3A Drive.
