6mm ID SMOOTH RINGS for APC E
These are precision machined from hard aluminum to insure a wobble-free, perfect fit of APC E props to collet prop adapters. The OD of the rings are all the same - 9.55mm - to match APC 'E' Prop's precision hole. The 'smooth' rings have three ID sizes:
5mm - fits Prop Adapters which have an M5 prop shaft, like HP-ADAP-30L Collet adapter, MPJ-8031, etc.
6mm - fits Prop Adapters which have an M6 prop shaft, like QRP 4mm Setscrew Adapter, HP-ADAP-40, HP-ADAP-50, etc.
8mm - fits Prop Adapters which have an M8 prop shaft, like Hacker ACRO motors, AeroNaut, and other brands.
