This logger works with any timer. For me it would be a great tool to have in order to fine tune a system. I currently use a Jeti ESC that has no logging capability. Things I would love to know and have no idea what is actually happening are the throttle signal that is output by the active accelerator and what Amps am I actually drawing during the flight. You can fly 100 years with a system and if the system is drawing a max of 20A, for example, and if you run a 70A ESC then you have 100 years with 2-3 extra ounces of weight that you where moving around for no reason. I would love to use a 30A ESC if I can but I don't know that at this time. Another place for this is to different motors prop combinations. I think it is worth the investment. Once you have a good idea what works best in your model you remove the logger and fly normally, without it. Another use for it is if you suspect fowl play and you are not sure, you can reconnect the logger and compare notes.
Currently on my model only god knows what is happening in my system. I have no clue what throttle output commands are coming from the timer, also I have no clue what are the actual power requirements for this system, I would like to try a 5S a 4S with motors with various Kv values but have no idea how to find out if I am withing the system limits or where are those limits. For sure what i have now is way overkill, and heavy.
