What is a Watt meter?

A "wattmeter" or power analyzer allows you to measure the electrical parameters that affect R/C electric model 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 protect.

Why you need one

Without a wattmeter, a hobbyist is left to guess or estimate what's going on. This trial and error approach can rob performance and damage components, or worse. Pros know that you can't get top performance from RC cars & planes without the accurate information a wattmeter provides.

Easy to use

"Watt's Up" is easy to use. It's like jumper cables. Connect between a power source and a load and you can measure all the important electrical parameters. It doesn't interfere with the components you connect it to.

See example watt meter connection diagram.

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.
