Looks great. Works great.
Have had EI instruments in my past plane and current plane and they always performed flawlessly.
People [at EI] were great to work with.
While the installation is not quite done yet, I have seen the unit in my aircraft with the engine running and the monitor producing numbers. It looks very good and I cannot wait to go flying with it!
Your sales and support teams are very helpful.
I have seen your products in other aircraft and have seen their reliability.
The tach looks and operates amazing. Extremely accurate.
My mechanic said that your product was very good, and he was correct.
Awesome Tech Support. Like the functions it supports and the fit and look in the panel.
The FP-5l I had installed is easy to use and so accurate it’s almost scary. When I find a company that produces a product that good I stick with them. The fact that these instruments also look so darn good didn’t hurt either.
[EI’s FP-5L with Aux Carb Temp Option] gave me fuel flow & Carby temp & was easy to retrofit.
Really glad to have accurate oil psi and temp! [It’s a] match with previous [EI] installs.
