rc bearings
YS91SRS Engine
The engine had new front and rear stainless steel bearings about half a gallon ago from RC Bearings in the States.
It has just been rebuilt with a brand new piston, ring and liner, and has never been run since this was installed.
The engine will require a full run in as a new engine would.
The anodising on the side of the head has come off from rubbing in the heli's frames but otherwise its in very good condition as the pictures show.
A very powerful, regulated engine.
The box is included
Exhaust/Muffler/Silencer
The silencer is the Hatori 946, designed bearings for the YS91SRS engine. This is also in very good condition with no dents, only light scratches and marks from general handling.
Included is a brand new set, still in the packet, of fluorine O-rings.
The small silicone mounts and the matching washers have been trimmed on the bottom for clearance in the heli they were mounted on, not an issue but though i'd best mention it.
The box is included.
