EI representatives… have been very helpful, truthful, and knowledgeable… We had no idea, that a few weeks later [after our purchase], we would need to have a Top Overhaul. What great timing! Having your engine monitor installed in our plane will hopefully help us keep it out of the shop for further engine repairs.
Installing [EI’s FP-5L] in my RV 6. . . owned an FP-5L 6 years ago in a Cessna 206 on floats in a commercial operation in Alaska. Getting every ounce of payload, and coming home across Cook Inlet with the Cessna gas gauges near or on empty, I spent a lot of time explaining the benefits of the Fuel flow gauge… and reassured my passengers there were 12 gallons of fuel on board. I’m a believer…
The older EI ultimate engine analyzer that came with my plane that I bought 7 years ago has always worked flawlessly.
Best sales team.
Easy to install and everything you need inside package. Good price, nice instrument and simple to use.
Excellent Service, superb product.
Just about to begin flying with the EI MVP-50P, so no in-flight feedback yet. But I did study the user manual, then sat in my plane going through the screens, menus, etc. It was very easy and intuitive to locate everything, so I’m confident that it will become second nature to do this in flight… Very happy with all interactions with EI.
We chose your product because of the great support and reputation your company sustains.
The R-1-6 is a great instrument. [I chose EI because of] quality.
Electronics International is an exceptional company with exceptional products… Oregon company, great products and great people.
Keep it up. I’ll keep coming back.
