| Hyperion Aluminum SMOOTH PRECISION RINGS for APC E Props - 5 pcs 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
(note: MPJ 4703, 4704, 4705 have a 'step' at the base, so
cannot be used with the precision rings) |
