Application examples-Electro flight configuration monitoring

Here I will show you just few examples how Hibox can help in different areas.

First example is ordinary electro powered model. Engine is Model Motors AXI 2814/10 powered by 8xSanyo RC2000. Propeller Aeronaut Cam Carbon 10x6. From zoom you can read that increasing RPM by 22% (from 7740 to 9480 rpm) is increasing current by 107%(!) Hmmm, worth of thinking:)

Using integral function in User Calculations you can also calculate average current consumption in defined interval (red dash lines); 19,3A. Sure very easy you can also calculate maximum or average Power and many more. All values are transferred to Protocol Editor just by right mouse click, that's all. No software in this category allows you these computations and comfort!

See another example. Same motor, propeller, just source was 3S 3200 KOKAM LiPo. In this case also need to specify that ECS was Jeti-Hacker Master 70-O-Flight, because you need to set up ESC for use with LiPo. I set 3S 3V per cell cut off voltage.

You can see that motor time was aprox. 9 min. (very nice!) average Voltage 10,6V (3,5V per cell), average Current 18,7A and average RPM 7800 (I skipped that 1 minute gab in the middle). ESC cut off was 9,31V (3,1V per cell). Sure you can merge above mentioned file nicd.pwc with lipo.pwc and compare both variants. Soon I will make new 8cell pack from Intellect NiMH 4200 cell and let's compare it with NiCd and LiPo.

Application examples-Pb charger monitoring

Once I had chance to test nice Lead Acid 3-step charger. Question was if it's suitable for my winch batteries or also my Gel Traction battery. Thanks to Hibox I was able to log whole charging although this charger has no logging facility.

From log I found that limit voltage around 14,7V is not good for my batteries. Gel battery you can even seriously damage with 14,7V for more than 4 hours (see log). My PowerCube charger makes much better job in this case. When using overlay feature of PowerCube software you can see on the next picture, although I limited charging Voltage on PowerCube charger to 13,8V (preventing water evaporation), in the same time interval PowerCube charged C=39,6-35,48=4,12Ah more and at not so lethal high voltage (14,7V) as mentioned charger. Hibox helped me a lot. In this example you can also see cooperation of PowerCube and Hibox on the same analyzing tool-PowerCube software. I'm comparing logs from PowerCube charger and Hibox logger.

Application examples-F3B winch monitoring

As tidbit you can see how to use Hibox to measure currents nearly 600A! Yes, using external clamp meter and Hibox you can log such brutal phenomena like is F3B winch start. And even more! Using Hibox counter mode you can log every single revolution (don't mix with RPM, it's different measurement) of winch and then count how many meters of line you reel up before zooming your F3B jet.

On bellow showed picture you see that during launch (10sec duration) I used energy 6,8W. I'm sure that under specific conditions you can think as this energy is equal to pull effect of your glider and this is what you want to maximize (pull efect). Sure, you will compare it with altitude reached after this launch. I'm sure this is new point of view to winch launch optimization. I offer you this revolutionary solution

If we are talking about F3B winches, you can also very easy measure internal resistance of whole set (winch, battery). Under F3B rules resistance shouldn't be lower than 0.023 Ohm.

Just again connect Hibox with external current clamp meter and log Voltage and Current. Using user calculations you will calculate that internal resistance (mesured with fixed drum) of my winch is 0.025 Ohm. Worth of note that current was 507A! Comparing (using overlay function of PowerCube software) different winch baterries you can select the best one for your winch.
