All of the companies listed below represent the absolute best in their class.
I have to believe in a product and company before I will use it or add it to my list of sponsors – I don’t use parts or equipment just because it’s offered free to me. There’s just too much at stake. I’ve turned down numerous sponsorship opportunities because they just didn’t stack up to the competition. Please know that I fully recommend all of these companies and I am very, very proud to carry their logo on my aircraft.

Jim LeRoy

You can’t perform at an airshow unless you can get there. Jim uses Garmin Navigation and Communication radios.


Unison makes Slick Magnetos and Autolite Spark Plugs. They provide the ignition system for the Bulldog.

Jim uses Primashock for website design and maintenance, as well as ad and logo creation.


PPG provided the high tech, color changing, metallic paint on Bulldog II. Not only does it look cool but it stands up to the abuse of sun, heat, rain and high speeds as well.


The Bulldog is covered with fabric, yes fabric. It’s got to be tough and it’s got to be right. Polyfiber sets the standard in aircraft fabric covering.

The Bulldog II paint scheme was designed to make an impression. Aircraft Studio Designs will take your concept and turn it into reality, or create a unique concept for you.

Have you seen a cool paint job on a NASCAR driver’s helmet? Gary Hess probably painted it. He paints Jim’s helmets as well. Simply awesome.


Jim pushes harder and more frequently than any other performer, this means he spends a lot of time pressed against his seat belts. Hooker Harness makes the seat belt system that keeps Jim in the aircraft.


Bulldog II sports 800 square feet of vinyl, all done by Screaming Aero Grafix – the aircraft and automobile vinyl specialist.


Engine mounting systems in aerobatic aircraft are extremely critical. Barry Controls makes the mounts that hold the Bulldog motor on the airframe.


In order to get “big” power, everything has to be “bigger” including the exhaust system. Sky Dynamics provides the custom exhaust system for the Bulldog.

All instruments are provided by Pacific Southwest Instruments – a dealer and overhaul facility located in Southern California.
