RE: Data Logging
100% agreement here with Chad.
Anytime I setup a new plane, try a new prop, or try new software, I hook up a wattmeter (or the Eagletree w/ LCD) for a quick static run to confirm numbers are where I expect them to be. I typically data log every 10th cycle or so on each lipo to keep record of the lipo health and make sure the system is not doing anything unexpected. Even a full throttle RPM static check is valueable for assessing the health of the system...finding problems sooner than later can save a lot of $$$.
