The GT Power version of this product is on Ebay for only $12AUD with free postage. Much cheaper and i think the GT power Ver.2 is more accurate than the Turnigy.

they are exactly the same, different face plate.

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!.

How does it tell abt flight time
 Richard 506 points
there is no flight time, it isn't really meant to be left in a plane. Good for static testing. It does show total Ah and Wh.
 Baqar 32 points
It is written in specs that it can predict flight time
 Richard 506 points
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.

How do u know that current load is full
 Andreas KarnÃ¥ 9 points
It shows the times the current draw is over 1 A.

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?

make a little video, send it to customer service, get a credit.

Does anyone know what will happen if the reading goes over the 130A rating of this meter? I have an EDF that should peak at 168 amps and wondered if it still reads or shuts off or what. Its says it will go over 6000 watts on this meter, i was hoping it would continue to read watts even if it may max out on the amp reading. Victor

A little too big to mount anywhere on my cars. So, just relegated to pit tuning. Fun to watch anyway.

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 :-)
