About Us

Eric B. Robinson at Lindsay Municipal Airport


  We are located in the south hangar of (CNF4) Lindsay Municipal Airport, City of Kawartha Lakes, Ontario, Canada. We offer a wide range of aircraft services including maintenance for certified and amateur built aircraft, restoration, modification and repair. Our team can easily source used and refurbished aircraft parts, fabricate or repair sheet metal aircraft components and any fabric aircraft components for all types of aircraft. We specialize in V8 conversions for most aircraft and are a supplier of V8 conversion kits for owner installation. We also offer aircraft engineering services using 3D CAD computer software, fluid dynamic testing, 3D scanning services and reverse engineering and manufacturing of obsolete aircraft components. We are a distributor and installer of MT® Propellers and MGL® (E.F.I.S) Electronic Flight Information Systems. We are a Republic SeaBee aircraft specialist. If you are looking to own one of these remarkably historical aircraft, or you are lucky enough to own one and looking to make modifications, we are the experts!

Our History

Brian at 18 Months in front of Dad's first Seabee (CF-DJV)

Dad bought his first Seabee in 1949. He traded it for a tired J-3 and $500 dollars. Dad had planned on reselling the Bee at a profit, however he could not part with it after flying it home. I guess I come by my love of the Bee honestly. We purchased our present Bee in 1969. It was sitting derelict on the shores of the Hamilton Bay, and was a sad case. Damaged by the winds & vandalized by local kids, it definitely needed a new home. This Bee was strictly a flying boat; the landing gear had been stripped out - including all the hydraulic lines! The Bee had been operating in the north country supporting a hunting & fishing camp - truly every panel on our Bee has a story to tell.

We hauled the Bee home on a trailer behind my brother's 1968 Dodge Charger and put it back into flying service. We operated on a limited budget, and did only what was necessary for safety. This included a basic VFR panel only, with no radios or navaids, and an original Republic interior. Fortunately Dad was a talented mechanic and an excellent scrounger. He even found everything necessary to reinstall the landing gear. We flew the Bee on a sunny day on 22 August 1971.

Like Dad, I always figured we would fly the Bee for a while and then sell it. That was over 30 years ago! The Bee really spoils you for flying most other light planes with it's handling characteristics and utility. The only downside to the Bee was the underpowered Franklin engine. The Bee has a large cabin, and the Franklin had only 215 H.P. It was an easy plane to overload. Additionally, the Franklin's reliability was a constant concern. You really had to enjoy getting your hands dirty on a frequent basis & maintain a good supply of spare parts. If you go for a ride in a Bee, be careful: Seabee fever is contagious & it can be very difficult to cure!

Our Background

My love for the Sea Bee goes back a long way. My dad Eric bought his first "Bee" in 1950 when I was a very young boy. He operated it commercially & really enjoyed flying it. After I received my pilots license we bought our second "Bee" and I have been an active SeaBee pilot ever since. In my opinion it is a great aircraft, and easily one of the best recreational aircraft of all times. We flew the Bee with the original Franklin engine for 28 years and have many fond memories of the trips we made.

In late 1997, the Franklin was due for another overhaul and I had a decision to make. I believed there were three viable options for me:

  • Repair the Franklin again.
  • Install a Certified Aircraft Engine Conversion.
  • Install an automotive engine conversion.

Unfortunately, the last new Franklin parts were produced in the late 1940's. Overhauling a Franklin involves a resourceful mechanic, a lot of ingenuity and a combination of installing some automotive components (e.g. Crankshaft and rod bearings), reworking existing components (e.g. Camshaft), and welding up 50 year old cylinders to allow installation of modern aircraft valve seats and guides. After much effort, you still end up with an obsolete engine.

The most popular certified aircraft engine conversion for this aircraft involves installing the GO 480 series of engines. This is an expensive option, and the GO 480 engine is 1960's technology. Removing one obsolete engine to install another obsolete engine did not make a lot of sense to me. There are a limited number of other approved aircraft engines for the Bee, but the conversions are all expensive.

The automotive engine conversion option offered the following possible benefits:

  • Fuel efficient engines
  • Reduced maintenance costs
  • Improved power to weight ratios
  • Improved engine and parts availability
  • The option of easily including modern creature comforts (e.g. Heating and air conditioning)

Based on all of the above factors, the decision was easy. I decided to proceed with automotive conversion and set the following objectives and principles:

  • Improved reliability and safety over existing installation (500 Cu. In. Franklin rated @ 215 H.P. @ 2575 R.P.M.)
  • Equal or better performance
  • No change in flying qualities (I like the way the Bee flies!)
  • Minimum change to airframe structure and appearance
  • Ease of maintenance (component availability, visibility, and access)
  • Reduced environmental impact (mainly via reduced noise footprint)
  • Improved creature comfort (cabin noise levels, cabin heating and cooling systems)
  • Use commercially available stock components where ever possible.
  • KISS (keep it simple stupid!)
