Bill, How many RPM will it log on 2 and 4 pole motors?

I ordered one on the 4th. I am not in a hurry though... whenever it is ready I am sure they will ship it. It would be nice to get an update though since the website now shows the 15th but it still says it is pre-order.

I am looking forward to this. Anyone know a good connector to use for the ESC/motor tap wire? It shouldn't need much amperage I assume so I was thinking of a simple servo connector on it.

I think I'm just gonna skin the HS off one bullet connector and add a tap with the female end of a DB pin ( about 3$ for a db 25 printer kit from radio shack) Then repeat for each heli I want RPMs on. Putting a male on the sensor will allow pretty easy portability. Sorta like a micro bullet connector.

If you have only a few airframes to use it on you might be as well off taking the plastic ends off a servo extension and using the pins/sockets. That'd get you 3 done with no crimping, as you can use the attached wires.

Everything would of course be covered with small HS tube like the bigger bullets.

Hi All,

We have been the unfortunate recipients of this:

http://www.komotv.com/news/4935976.html

We now have power back on, and are using cellphones for internet access.

The mail has started to run again, and we are supposed to receive the brushless expanders from the factory today, which means shipping starting tomorrow.

Sorry for the delay!

Regards,

Bill, for Eagle Tree Systems, LLC

Hi All,

Thanks for your patience. We are shipping the Brushless starting today! We'll get all the preorders out as quickly as possible, presumably by Friday.

Got mine today. All hooked up but should I use 1:1 for gear ratio for Align 430L motor? I used 11.538 (150t / 13t) for gear ratio and 6 poles and it seems like the RPM values are almost 12 times more than they should be.

Hi xStatiCa,

Can you graph "Prop RPM/Headspeed" and see if that looks correct? The "RPM" field is actually the true motor RPM. We need to relabel that to make it more clear.

Thanks! That is all it was .

I love this brushless RPM sensor. Much easier to get this to work than the other ones.

How does the 'I want high resolution RPM' advanced hardware option affect tthis sensor( or does it)? Is there a downloadable PDF that explains some of this stuff?

I can't use the help menu option with the software because windows vista does not have the older help system anymore. I don't know if it is explained in there or not.

Hi xStatiCA,

That option increases the resolution of RPM readings, especially at higher RPMs, but has the downside of somewhat reducing logging time.

Looks like we've got some work to do for help with Vista!

Bill,

An enhancement please,
I have a number of twin engined electrics Gws-262, GWS-38, A10, and others

Could we have two RPM sensors with a graph that plots rpm differential that would be real handy for setting up throttle curves and balancing motors.
