Greetings,

Someone in the surplus engine group posted a link to a current auction for these. Does anyone know who made them? I'm betting they were being built by someone who went bankrupt, which would explain why they're here. Anyone in AZ willing to pick these up if I get stupid and bid :-)

Below is the link to the site, which seems to be very poorly behaved. Select "aircraft and aircraft parts", and you will see only these engines. Below is also the info that was in the ad.

AR801R Single rotor water cooled engine with reduction drive

This, as the AR801, but is a tested and proven, lightweight, single rotor, liquid cooled engine with integrated reduction drive.

AR801R Engine - With Reduction Drive

Design Features.

Reduction drive giving high propeller efficiency.
Low levels of vibration.
Economical specific fuel consumption
Suitable for either tractor or pusher installation.
Low maintenance requirements.
Validated durability to FAR-33 type standards.

Technical Specification

Type	Wankel-type rotary, spark ignition engine.
Displacement	Single rotor - 294cm³ per rotor.
Power Output	53 kW at 6000 rpm. Alternatively 68 kW at 8000 rpm.
Weight	24.5 kg as illustrated including 2kw generator. Installed weight with cooling system is around 29.5 kg.
Vibration	Nominally zero (± 20 cm gm) radial imbalance. (Peak-to-mean instantaneous torque fluctuation is 4 approximately.)
Housing Cooling	Water-glycol mixture with toothed-belt driven pump.
Rotor Cooling	Air-cooling using belt-driven centrifugal fan.
Direction of Rotation	Anti-clockwise ( looking at face of prop flange).
Ignition System	Electronic CD system with magnetic triggering. 12 or 28 volt option. Fully duplicated system firing twin spark plugs.
Carburettors	Diaphragm-type. Version with altitude correction device (ACD) is option. Close-in mounting minimises possible icing problems. Alternative EFI system option.
Exhaust	Exhaust stub pipe without silencer.
Fuel Type	Regular grade (min 92 RON), Mogas (leaded or unleaded) or AVGAS 100LL.
Fuel Feed	Electric pump. (12V or 28V).
Lubrication	Total loss via metering pump from separate tank.
Oil Type	Mobil Pegasus 1 (or equivalents).
Oil Usage	224cm³ per hour at 6000 rpm and proportional to rpm.
Starting System	Via external cranking at propeller hub.
Generator	Alternative types giving from 0.9 to 2.0 kW.
Mounting	Platform or bulkhead mounting via 4 x M8 bolts.
Reduction Drive	Integrated lightweight belt driven reduction drive. Standard ratio = 1.93 with alternative ratios in range 1.6 to 2.2.
