Wattmeter with 'memory' for helis?

[Tom Mann]

Wattmeters typically go inline between motor and ESC, and display voltage, current draw and power consuption in REAL TIME.  So, for a fixed wing you leave the canopy off and stare at it while you run the motor up.

Somehow this loses its appeal when dealing with a 1m diameter main rotor spinning at 2000RPM.  I personally won't be anywhere near the thing to look at it, as I am quite attached to my appendages.

 Has anyone seen a product that will store historical data and present a report (average, peak, max/min etc?

Come to think of it this would be a touch for fixed wing too because you could get a report based on a real flight (surely more valuable than a ground run).

Tom, I think the Hyperion E-meter may do what you want, check Robotbirds.com. Roy.

I seem to recall something about this one being unavailable for a while due to re-design?

Problem with most of these "wattmetery type thingies" is they are a bit heavy and bulky for onboard use, and if the money can allow it, a better bet is something like the E-logger ( link here )http://www.eagletreesystems.com/MicroPower/micro.htm

I agree with Timbo, I use an Eagletree E-Logger, about the size of a receiver, stores the data which can be downloaded onto a PC at home (Or if you are flash a laptop on the field). With the optional LCD screen it can also be used as a wattmeter.

many thanks y'all for your replies.  I'm going for eagletree it looks pretty slick.  For any UK readers who want to buy: you have to get onto their UK dealer's site https://www.rc-log.co.uk, it worked out at £63 for the logger and whizzy add-on screen to read output.
