A "watt meter" or power analyzer allows you to measure the electrical parameters that affect electric R/C car and truck performance and safety.

A precision instrument, our "Watt's Up" watt meter replaces an ammeter, voltmeter, wattmeter, Amp-hour and Watt-hour meter and does more.

It costs less than the combination of those devices and only a fraction of the total investment in your RC modeling hobby that it helps to tune and protect.

Why you need one

Without a watt meter, your have to guess what's going on with the electrics in your model.Pros know that you can't get top performance from RC cars & trucks without the accurate information a watt meter provides.

Lots of applications

You Need One!

Why you need a RC Watt meter.

Just wanted to let you know I LOVE this meter! I'm playing around building CD ROM motors and the meter makes it so easy to objectively evaluate the performance of each motor. I am also very pleased with the size, construction and ease of use.

Thanks for a great product! - T.S.
