Why the Franklin Engine?
As you do your due diligence preparing to make the significant decision of engine selection for your labor of love, why would you consider the Franklin engine? There are a plethora of power plants available.
Some of the questions you might wrestle with are:
- What does it weigh, I mean really weigh?
- Will it fit?
- How easy will it be to maintain?
- Do I go with the newer generation models with all the bells and whistles?
- What kind of support can I expect down the road when issues arise?
- What is the best cost/value?
The experimental category is wonderful in many respects. The down side is that we are providing the data base for the manufacturer. Extensive testing in most cases has not been done, so we want to weigh heavily the history or lack thereof of the power plant. Some of these newer models run at a very high RPM requiring additional cooling systems to control operating temperatures, some incorporate high tech ignition systems and fuel control units. Nice on the surface, but all designed to deliver maximum horsepower at minimal weight and tolerances. It all sounds good but at what expense? Durability could be an issue. Will if fail and how will it fail? Will you be able to work on these in your hanger or able to work on them at all?
At the other end of the spectrum are the more traditional engines of which the Franklin is. The big two and Franklin have engines whose original design date back in the 1940’s and 50’s. This doesn't mean that the engine you purchase today has not evolved and been improved upon but means that the original design was strong enough to with stand the test of time. Designed with redundancy and simplicity in mind these engines have decades of operating history. No surprises here.
The Franklin engine, specially the 4A-235 that I am addressing here delivers 125 horsepower weighing 235 pounds fully configured. Updated options include, light weight starters and alternators, electronic ignition and Throttle Body fuel injection systems. Major internal components can be inspected and in some cases removed for repair or replacement without removing the engine from the airframe. The cylinders last almost indefinitely as with a simple cylinder liner replacement it is brought back to new tolerances. Air cooled, no reduction drives, FADECS or radiators to break all lower the cost of operation. Maintenance can easily be done by you in most cases due to the simplicity of design.
When it comes to cost/value you will find Franklin Aerospace more that competitive as we are locally owned and not supporting an employee base numbering in the thousands with money flowing overseas.
Our overhaul component, Southern Aero, is a Franklin dedicated company that is housed within the Franklin Aerospace facility. Coupled with an existing inventory of over 500,000 Franklin components with more being added on a continuing basis, the issue of ongoing support is assured. In addition, the ever improving relationship with the Certificate holder in Poland will help assure the supply of critical components in the future as we support and develop the experimental and certificated community.
Come by our booth (NE 30 & 31) at Sun N Fun and lets talk. I look forward to meeting you and discussing how Franklin Aerospace can deliver the engine that meets your needs.
