| watts up meter
thought id share this video i just made.. testing my watts up meter on my Axial Wraith.. tekin 13.5t rated at 201 watts 3s lipo 4500mah 35-70c mmp esc w 32p 54t/18t gearing barely gets above 60watts... tested it again...from dead stop to full throttle it went up to 105watts for a split second then back down to @50-70 watts info on watts up meter.. Works with any electric airplane, helicopter, car or boat model High resolution on all measurement ranges to accurately check battery battery pack cell balance and measure single cell packs Connects like jumper cables and troubleshoots poor performance, crashes, charging problems, battery capacity, ruined batteries, erratic receiver and servo operation and many other common electric model problems Readings are easily reset, even without removing power, by adding an external pushbutton connected to the reset signal of the meter's auxilliary connector, The full user manual (v1.7) at the RC electronics has details on this function. Sets cutoff currents and voltages, compares components and detects wear prior to component's failure Measures eight essential electrical values; Captures Peak Amps, Peak Watts and Minimum Volts events as short as a fraction of a second Current: 0-100A Peak, 50A Continuous, .01A Resolution Charge: 0-65535mAh, 1mAh resolution Power: 0-6500 Watts, .1W Resolution Voltage: 4-60V, .01 Resolution (0V min. using auxiliary receiver battery Energy: 0-6500 Watt Hours, .1Wh resolution Powered by circuit-no battery to change 16 character, 2 row LCD display 8 MIPS microprocessor and DSP firmware for highest performance Last edited by ROLANDROCKSHOP; 01-31-2013 at 08:58 AM. |

The only thing of interest to me would be the readings under load. Put it on the ground Let's see what it consumes then, and even better, what is the max rating in a bind situation? cheers braq |

Definitely a difference under load. The other thing is that the Tekin Redline 13.5T motor is probably rated at 201 watts @ 7.4 volts. Something fun to do with the Watts Up meter is to use it for measuring servo 'Stall' current draw. This information is somehting that servo manufacturers have never really offered and in this hobby is pretty relevant. If you are going to test your servos with the watts up meter for stall current be careful if you use something like a CCBEC for a power supply, you are better off using a power supply or 6 volt battery. |
