Brushless RPM Sensor Installation
Hi,
I am trying to work out how to attach my brushless rpm sensor to my motor/esc and I was wondering how other people have done it? Pictures of your installation would be great. I would preferably want to be able to connect and disconnect the sensor easily. Thanks.

I don't have any pictures but I basically used servo wires, stripped the two ends and hooked up to the connection between the motor and ESC, just like that. At the other end, the end that connects to the Elogger I hooked up a small connector (your choice). That piece of wire stays always on the heli but since I now have connectors, I don't have to pull out the motor and ESC wires everytime I want to perform a readying. It works for me since I have several models and some of them are already to separate the motor from the ESC so I figure... I do it once and leave it alone until next time. This also allows me to move the Elogger from unit to unit without much hassle.

some folks are soldering small stick pin's to the sensor wires, then you can stick them in the esc wires through the insulation. very easy to add/remove then.

I ended up using using a JST connector and soldering the two female ends of the connector onto 2 of the ESC wires where they connect to the bullet plug and it works great

That's exactly what I did but without the soldering. I did it for my 4 helis and it took me from beginning to end about 2 minutes once I had the JST part set up.

For some reason I was thinking you could monitor 2 motors with this sensor. Eagletree instructions are almost non existant. Does it matter which wires you connect them to? I like the idea of using jst or mini deans for this so I could easily switch the monitor out to another model.

I have a question as I'm also setting up the Brushless motor sensor. Once the two unconnected wires are attached to any two motor/esc wires, does it matter if the plug is connected to the RPM port vs the throttle port?
The eagletree v3 manual says when using the throttle port to remove the black wire from the plug & connect it to temp3, the red wire is then placed where the black wire was (on the plug.) Does this give you a temp reading you wouldn't get if using the RPM port? |
