Warner 185X Radial Engines

We at the Monocoupe Aeroplane Corporation of Grantville, PA, are pleased to announce the signing of a license agreement with Warner Engine Company, LLC, of Palmer Lake, CO to begin production of the Warner 185 radial engine for the experimental airplane market. Monocoupe Aeroplane Corporation was incorporated in Pennsylvania in 2016 with the intent of producing a Clip Wing version of the iconic Monocoupe two seat airplane kit for the experimental market. Kits should be... available for delivery by summer 2017. When looking for the perfect engine, we looked at the original Monocoupes power plant and started researching the Warner engines which led us to Mr. John Duncan, owner of the Warner Engine Co, LLC. We knew that the perfect choice would be the Warner 185 which was rated at 200 hp for takeoff and 185 hp constant at just 2175 rpms. With today’s modern technology, better materials, using higher compression and fuel octane and the addition of fuel injection and electronic ignition, we project the 550 cubic inch radial will produce in excess 275 hp.

This is a historical moment in aviation as we build an updated version of a radial engine that went out of production over 70 years ago. We are working on CAD drawn models that will enable us to produce the engines using modern CNC machinery and advanced machining techniques, all of which will lead to a higher quality part with tighter tolerances. Plans are for the engine to have billet aluminum cases, jugs, and heads machined on CNC 5 axis mills right here in the USA. We are working with the leading engine parts companies in America to produce everything from pistons and crankshafts to updated ignition and charging systems. Our business plan includes an in-house dyno so we can run every engine prior to delivery to insure the highest quality product available. We know that this engine is a game changer for the experimental airplane market due to its relatively compact size and high horsepower and torque. Customers will now have a choice to use a radial engine on a broad range of airplanes and have power that was previously only available in conventional flat engines. Not only will our customers be able to have a brand new, high horsepower, radial engine built in the USA, but they will be part of the next chapter in the Warner engine story.

We have allot of improvements planned for the new Warner 185X experimental engine. Some of them are:

CNC machined case, jugs,and heads
Steel sleeves
Fuel injection
Magneto and electronic ignition
Improved cam profile
Higher compression
Updated crank,master rod,and connecting rods
Tighter tolerences
Higher horsepower and torque

We are taking $500.00 deposits for build slots for the Warner 185X engines with an introductory price of $40,000 for the base engine. Projected deliveries will begin fall 2017 after Oshkosh and you will be assigned a serial number when non-refundable deposit is received. All engines will be run on our in house dyno for one hour prior to crating it to check for any leaks and to tune it. The engine will be ready to start when delivered and will include the dyno sheet for the engine. All engines will include a 12 month limited warranty that will begin when the engine is installed and started on the customers airplane.
