Using a phase sensor with Jive ESC
To monitor head speed on the Vcontrol with a Jive and phase sensor do I need to do anything besides plug the sensor into the Vbar?

Yes, the signal lead goes into RXA at the top pin and the power leads have to be Y harnessed from the servo leads. It also has to be 5v...Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

Got a chance to hook up the system tonight. I run 7v to my servo's with a WR BEC. So my jive leads were free. I hooked up the phase sensor and set my Jive BEC voltage to 5v. Went out for a test flight and it popped right up. One problem, when I spool up in FM1 the number shows correctly. When I flip to FM2(idle 1) the number skyrockets to around 4500. NOT correct, then when I flip to FM3(idle 2) the number is rock solid at 1600, that's correct. What is my problem?Team Synergy, Team FBL Rotors-------if its not broke...it will be!

Disconnect that, do not fly that again. Yu have two different BECs working the same electronics….you are asking for failure. You need to either use a voltage step down off of the WR BEC or the Jive BEC but NOT both.Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

I don't understand why this needs to be 5v. I have the power completely disconnected with only a signal from the jive into the Vbar. Also only a signal from the phase sensor. Is there voltage back feeding from the sensor on its signal line?Team Synergy, Team FBL Rotors-------if its not broke...it will be!

Signal is still sent with voltage, the max input is 5V....Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

Hmm, alright. Ill try and do more this weekend. Is this why my HS went goofy in only 1 flight mode?Team Synergy, Team FBL Rotors-------if its not broke...it will be!

You can keep 7v for your servos if you tap into the power from the rx1 or rx2 ports on the side. They put out 3.5v for spektrum satellites regardless of bed voltage. That's what I did. Just separate the signal wire from the power wires and plug the signal into the top pin of rxA and the two power leads into the rx1 port. Mr. Mel did a video on it.

You can do that but if you short that lead, you take out the entire VBAR as well so be careful..Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!

I kept the 7 volts, made a custom diode to drop the voltage to 4.4 final to the phase sensor, tapped into one of my Bec leads, works like a charmTeam Synergy, Team FBL Rotors-------if its not broke...it will be!

Nice. Alternately you could just get a Hobbywing phase sensor. They can take up to 8 volts.

I have a hobby wing, the phase sensor is not the issue. The Vbar is. 5V max on RX A as statedTeam Synergy, Team FBL Rotors-------if its not broke...it will be!
