"Maybe that's why im having to land at 2500mah. I assumed the current sensor was wrong because i had to go in and mess with the voltage to make it accurate.

You had a similar experience?"

Jeff Colhoun replied to Jeff Colhoun's discussion voltage in readout wrong in IRIS
"Yeah its not that im afraid.  It shows this same reading on my minimosd which is what bothers me.  This is my cheapo fpv rig.  I just wired it up with bluetooth so i could connect my phone whenever and change parameters easily."

Jeff Colhoun replied to Jeff Colhoun's discussion voltage in readout wrong in IRIS
"Yeah that parameter is at 12.02. Ill fiddle with it to get it right. Its kind of silly when i first arm it and take off seeing my voltage go to 11.4 volts.

Thanks!"

"probably flying a phantom.  I had to call them and two different sales reps told me to order it on the web site.  Finally number 3 knew it was not and i got it overnighted.  Just finished the install and test flight."

For some reason my ESC stopped working.  If i plug in a battery nothing.  If i plug in a spare power module to my pixhawk everything lights up and i can connect via mavlink.  Where can I buy a replacement??
