Quite impressed with this new tool
Takes a lot of the heavy lifting away (setting up/configuring the BF log viewer to look at the relevant filter data, setting up Pidtoolbox with its steep learning curve - and a monthly fee now,..) - and gives you what you exactly need to fine tune).
Only limitation is that it only takes up to 10Mb log at the time - but not a show stopper as you really want to tune with short to the point flights to avoid damaging possible hot running motors or similar.
(10Mb gives you a couple of mn max)
Browser based so can also be run in the field offline - cool stuff
