Opened V120D0S2 Telemetry
 

I installed the motor temp sensor, and loaded the software, and it works well
chopper will hover indoors at 11min 50 sec , land at 3.4 volts and the little brushless is running a constant 102.2 deg. I just love this little machine. It is almost indestructible. I've hovered it into several plants. LOL
the softest most likely replaced part would be the tail rotor shaft, so get an extra when you order. Mine was off about .05 mm, straightened it out by hand. I have it bound to a Devo12S. I love it as well. their are a couple things Id change with it I hope Walkera will. One is your timer is not on the same screen as the Telemetry data. also wish it had datalogger. and needs to record in mph. Plus telemetry like beeps as along as they are linked, if yo fly out of telemetry data range it stops. Id like it to be the other way around.
