Customer Testimonials

I won a FP-[5]L and had it installed in my c150. I was/am impressed with the accuracy and ease of operation of the FP. I wanted a new tach and I trust (and verified) that the EI R-1… would be my best choice. I am not a rich man. These instruments are affordable and incredibly accurate. Already planning my next buy from EI.

We’ve worked with EI for years and love the product and support always received. Quality & dependability.

Tammy B. from North Carolina
Air Tractor AT-802

Easy installation, lightweight solution. It looks good and is easy to use.  [I chose E.I. because] I needed to replace my old Hobbs meter.  This provided more functionality, allowing me to remove my old digital timer, and EI programmed it to my current airframe time.

Rutan Model 61 Long-EZ

EI has the best customer service of any company that I’ve ever dealt with.
