The TURNIGY watt meter is a very accurate R/C amp/watt meter.
Predict model airplane flight time with any given propeller. Ensure peak currents are safe for motor, ESC, wiring and connectors Check battery health and performance. Evaluate R/C battery charging efficiency. Choose the best propeller or gearing and the most efficient motor Check for wiring and connector power losses Measure power and energy consumption of ANY device with a battery
Operating voltage: 4.8~60V (0V with optional auxiliary battery)
for that purpose you'd need to wire it in a circuit using diodes to have normal current bypass the meter and reverse current go through the meter.
The diodes would impose a voltage drop and thus reduce power available ....
Better to find a device actually designed for the purpose. They are made but you won't find it here.
Yes, Same internals same build, But from what i have read and seen, The GT is slightly more accurate, So they must calibrate the GT differently. I don't know what they do, But the GT is better, And cheaper!.
IT means the device gives you the information you need to predict your flight times. If you know your current load at full and half throttle, then you could predict flight time based on your battery size and flying style.
Guys, I need help. I have connected WM to battery and an ESC. It is showing zero readings at all times. Even after I have turned on the motor, all readings were "0". Wiring was done like in manual... Anybody with the same experience?
it work's great nice blue backligthing makes it easy to see for us night flying guys. the only thing i would like to see is longer wires on the meter. mine were only about 3inches long 6 would be good. 4 stars for the short wires. still good for the price.Thank's HK
This box toggles through the several measurement parameters. The parameter can not selected individually. However this works also. A little bit bulky to go fly with it. Especially on a 450 clas heli. No problem to fix it on a 500 class w/o canopy. Nice gadget every enthusiast should have :-)

Great meter, had some problems at first, but it all worked out. Turnigy is a great company!
