Amazing aftermarket service. Good quality products
Very happy with our new tachometer!
MVP-50 is a really great product
Works Great! Getting used to menu the more I fly — Nice addition to airplane.
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!
