What kind of sensor are folks using to record RPM?

cfmorrell · 03-23-2009, 01:02 PM

I use the brushless motor sensor. It's the easiest to install, as it's only a wire attached to a ESC->Motor wire. No magnets, no other sensors, etc.

Ok.

It tells you the HS? Does it do a calculation based on info you give it in the software or something?

cfmorrell · 03-23-2009, 01:39 PM

Yes, when you set up the logger, you tell it pole count and gear ratio, and it calculates headspeed based on motor speed.

Cool!

+1 for the brushless rpm sensor

+2 for brushless sensor. Ive now got all my helis (3) set up with the motor sensor wire to a small plug so I can move the elogger and RPM sensor from heli to heli rather than needing three RPM sensors. The Eagle tree is a great little gadget and invaluable for setting up a new heli or improving collective management.

+3 Its a great tool for dialing in the RPM's and watching how your packs are performing.

gitmomike · 03-23-2009, 08:30 PM

Which one do most of you use, the 100A or the 150A version? With wires or w/out?

cfmorrell · 03-23-2009, 09:01 PM

I got the 150 for possible future use. I don't ever get over 100, but I figure if I was buying it, I'd rather go all the way. I got the wires, just because I was afraid of connectors breaking off of circuit boards.

I have the 100A and 150A loggers with wires because I use Anderson Powerpole connectors. I also have the hall-effect sensor for headspeed. I prefer the direct measurement based on the main gear rotation rather than a calculated measurement from the motor pulses and gearing.

Hall effect pickup with the little magnets. The main gear even has a place for the magnet to go. Mounted the sensor on a bent paperclip bolted to the frame. Seems really accurate.
