Paul:
The new Castle ICE series ESC's have built in dataloggers that work real well.  Prior to that we used an Eagle Tree to good effect, do not know anything about the Hyperion.  One advantage with the Eagle Tree (versus the ICE) is that it will let you hook up different kinds of sensors, I think Alan Hahn used it with a Pitot-Static tube to recored actual airspeeds.

Paul,
I have the Eagletree and an ICE50, and the Eagletree offers some advantages over the ICE. Mainly I think it is being able to add extra sensors and the current sensor is better calibrated than the ICE).

On the other hand, the ICE has one feature which can't be beat--it's called "Motor Power Out" ("MPO"). That quantity tells you how close you are to full throttle during the flight. As long as you never reach 100%, you are doing ok. It can do this because the ESC knows what throttle (PWM width) it is commanding to the motor. The Eagle tree can't give that.

If I were just starting out, the ICE really would be what I would want for CL. That "MPO" will tell you how close you are to running out of battery during the flight. Plus of course you get the other stuff (rpm, volts, amps, power out, and something called Voltage Ripple--it is the difference between the battery voltage with power on -voltage with power off (during the on/off period of the PWM). I am seeing something less than a volt, which is apparently "ok".

So I have both, but not the Hyperion e-meter. It might be pretty nice too.

Hi Paul,

What all the others have said. .... I really like my Eagle Tree setup.

Yes, it comes with a link to their software. The SW has everything you would ever need. I set my computer screen up to show all the readings like a FS planes instrument panel. You can do print outs of data and graphs and keep records on every flight if you want. It is an excellent piece of equipment and worth every penny if you like to experiment with different setups. It is well worth it's modest price.

I use two temp sensors (one for motor one for battery), RPM and Air Speed.

I have the powerpanel to plug in at the field but I don't use it much. I just took my laptop to the field and uploaded the data from the plane. After a lot of testing in the beginning, using the ET system, I have not used it or any other piece of test equipment for the past 300 trouble free flights. :-)


Here is their link, it should answer all your questions.

NOTE: For those in the wings reading this thread, please don't misunderstand our use of all our "techie" equipment stuff, IT IS NOT NEEDED! It is only needed by us AR types. ECL is "plug and play", (no test equipment needed), if you use one of the tried and true set ups available.


Have Fun,

V3 logger with leads- Yes or No
Brushless motor rpm sensor ( splice in type) Yes or No
Micro temp sensor or loop type ?
Thanks
Paul

Thanks

I agree with both Crist and Rudy. My ET does not have the extension leads.

Sometimes I wish I had leads because the area is getting a little crowded and I think leads would help. However sometimes there is just too much wire!
