Eagle Tree Datalogger on the horizon for me, anything I need to know

If you use deans, definately use the one with integrated deans, which i have found very convenient. I have the brushless rpm sensor too. It's pretty accurate for measuring kv and max rpm under a load, but i gets a lot of erroneous readings, and i never see a smooth curve on the graph. In fact it is practically useless at rpms less than 15,000 due to some sort of electrical interference that occurs at low rpm. The beeps on the MMM cause it to instantanously read over 50,000 rpm for crying out loud. I also have the temperature sensor. Its good for see how fast your motor heats up during a run and how effective your airflow is. However, even smothered in thermal paste and tape to hold it in place against my motor, i get temp readings that are up to 30 degrees cooler than my infrared sensor.
