ET Announces Standalone G-Force MicroSensors, starting at $26.99!

Need to know how many G's you pulled in that last barrel roll? Eagle Tree is pleased to offer the world's first standalone G-Force meters for RC models.

The tiny, low cost sensors measure G's in the X, Y, and Z axes during flight, and the maximum encountered forces on each axis (in 10ths of G's) are displayed on the built-in 7 segment LED.

Of course, the G-Force Microsensors are fully compatible with our eLogger V3/V4 and OSD Pro products, and provide real-time logging, display and graphing of of the G-force data when used with these products.

Each unit is factory calibrated, with no user calibration required. You can even use the G-Force MicroSensors in your own Firmware/Microcontroller project.

There are two models available:

* 3-Axis G-Force Microsensor, up to 8 g (7 g minimum) (MSRP $26.99 USD, p/n GFORCE-LOW)

* 3-Axis G-Force Microsensor, up to 40 g (38 g minimum) in X and Y axes, and up to 8 g (7 g minimum) in Z axis (MSRP $63.99 USD, p/n GFORCE-HIGH)

Well, this is great!!

Could people post what maximum G they see on various models ? That would really help the rest of us choose which is adequate for our intended use.

Is the 8G version easily maxed out ?

edit : deleted some questions I found some answers in the manual.

The PDF manual states: "The JR/Universal servo end of the Standalone Cable connects to a spare Receiver channel or small battery. Note that the voltage must be between about 4V and 16V (4V to 6V for the High G sensor). Do not exceed 16V with the low G sensor, or 6V with the High G sensor!"

Is this a _nominal_ Voltage maximum or a measured Voltage maximum?

Our planned installation uses the High G sensor and a 5-cell NiMH pack driving a 2.4GHz radio system. When fully charged this battery pack puts out up to 7.2V for a very short time, 6.4-6.6V over an extended time. We can't use a 4-cell pack.

anyone ?

B2Streamlines, the calibration of readings above about 7G will be off at voltages above 6V. Further, voltages above 7V may damage the sensor. A possible solution is to insert a standard (not a schottky) diode between the battery/rx connection and the + (red) wire going to the sensor. That will generally drop the voltage by about 1+V.

Short question!
Can the wires on the G-Force module be extended , seeing is how sort they are.
If so will it have any affect!

Yes. ET sells an extension cable, or you can make one.

High G sensor and FDR

How and where onnect the G sensor with the FDR. If tried onto G-Force port it seems that is not the right port and nothing is recorded

Does anybody know about how many G-s can be expected at the landing?

Would it reset the maximum value?

With my Funjet i got about 10 G-s by pulling like crazy, but since it lands on it's belly that number might be exceeded.

G sensor calibration

I have two of the low G sensors. The first one would read .92 sitting on the ground. I updated to he latest firmware and now it reads 1. The second one I recently installed in another plane reads .92 with the latest firmware. I see there is an option to calibrate, but it's greed out (not selectable). How do I calibrate it?

Frenchy Tomcat, missed your post earlier. The G-force microsensor is not compatible with our flight data recorder. There is a separate hi-G sensor availble for that, on this page.

Randy, there's not a way to calibrate the G-force microsensors. I'm not sure why your unit is doing that. Did you buy the two units at the same time?

Glad to replace it for you if you'd like.

Bill, for some reason it is working fine now. Reads right around 1G sitting on the ground. So, no more issues :-)
