It worked fine for a few flights, but at some point one of the cables broke from the solder. I am not very skilled with a soldering iron or want to try to fix it, but beware that the connections may be weak and try not to bend it very much, if at all.Must have product if using the HKPilot or any APM derivatives. Pretty much does what its supposed to. I ended up frying one by having one of my motor leads reversed but thats completely my fault. Would be nice if it had some sort of reverse polarity protection but I dont blame the design, more of a bonus feature. Overall great product and does what its supposed to!jabnfauibhuibdhasvgibhdfaspuivbhdfasjuibvhdubhvjuidsbhvfjuibdfsvgjuibdfasvg
poor soldering..........................If you solder it the right way it it provides reliable information..Good stuff, works as advertisedWorks well, and valuevery easy to use, ............. you need to have it, very interesting ..............., ........... very nice .. goods, works fine ......., ...........Works perfect once calibrated. Using the 433mHz Telemetry set connected to my smartphone, the battery status per 10 percent is spoken through your phone speakers. Great!great module for hkpilot. i dont need a separate bec anymore. they should sell it as a kit with the flight controller.
