Product Description

FrSky Battery Voltage Sensor FBVS-01 gives live BATT monitoring for Rx with Two Way Telemetry ; suits LiPos from 3v-> or 4s  or upto 19.8v (5S)  . There are three voltage ranges to choose: 1S lipo for battery voltage range from 0V~6.6V, up to 3S lipo for 0V~13.2V and up to 5S lipo for 0V~19.8V. Please check the battery voltage division ratio for each option below:  As supplied works well for 4S or 3S.  Requires soldering to Andromeda outer ring ; or DIY solder to pins(not included) for the LiPo balance tab as shown here below with FrSky X4R A2 port connected to the FBVS-01 and the 3S LiPo Pins - the A2 voltage is then activated in the Taranis telemetry section and a Play Value assigned to a switch, then go to Telemetry page and calibrate the voltage (you need a DMM to first see the current voltage of the battery).



The FBVS-01 is typically combined with a D4R-II and a BARO Variometer to give live altitude data. The D4R-II from FrSky (sold separately) is a favourite Rx for C-PPM enabled mini Quad controllers like our Aussie PARIS v2 Hero. and HERO•32 bit naze becuase it is compact, has 1 wire 8 channels ; and can easily be connected to the voltage sensor FBVS-01 and the Variometer SPort with our D4R-II hack below (without any HUB needed!)

  • Information on assembling a kit can be gained by looking at the photos on the product page itself. If you stuck on an advanced kit then first read the Quad Noobs guide
  • MultiCopters should hover at 50% throttle and fly for 10-15 mins.
  • Balance all props - vibration causes junk sensors data and gello in video - remove the SOURCE of the vibration by balancing
  • Use a quality prop balancer(Du-Bro 499 Tru-Spin Prop Balancer) statically; then run them individually to check they are centred true and the tipshave the same path; any vibration will reduce the effectiveness of the Wii gyro or anyother gyro.
  • Attach any IMU or sensors such as Sirius™, NAZA or WookM with vibration isolation gel - Board with sensors solder to directly are just cheapo clones - commercial quality IMU use isolation vibration materials
  • Keep your PROPS OFF - not installed - until you are fully conversant/understand in full the functions of your Tx in full including TRAV (end Points), the arm and disarm procedures - realise that for a noob skiping or out-of-order set-up steps or moving sticks, or even static - PROPS may start at anytime without warning. Never install props prior to calibration of the ESC and testing the gyro orientation, and arm/disarm testing of the board - YOU are responsible - make sure your actions and your Copter is safe - remove the prop -remove the risk.
  • Always maiden on default PIDs' - If the copter is not almost perfect on default PID's then DO NOT go straight to altering the PID's! Most of the problems you will face as a noob will be caused by making wild assumptions or following myths from forums - fly on default PIDs first - balance your props - make sure your ESC are calibrated and synchronized.
  • Dont be fooled by forum claims of kirby flashed ESCs - this software will melt your ESCs and give short flights - there is a lot of bad info on forums

Safety in Australian Skies

  • Keep more than 30m from persons,choose an empty sports field for your first flights
  • Do not fly near pets, houses or cars
  • Never fly within 3nm of an airfield or above 400ft
  • Never install your props until after the Multicopter is fully tested and 100% correct without props. Engines can start suddenly and without warning IF YOU FAIL to understand how they work or skip any steps.
  • Set your Tx/Rx binding to low throttle 1/4 position so that if the link is lost the copter will descend slowly.
  • Always keep your Copter in line of sight for one pilot ops - FPV is only legal in AU with a buddy on a buddybox - 2 person FPV is 100% legal using the buddybox system below 400'.  See CASA Part 101 Regs
  • RC Flying is a privilege - please enjoy it.  Don't show off and don't get over confident
  • Home movies are fine, but in Australia professional paid photography or videos from an RC aircraft requires CASA Part 101 compliance, including exams and approved ops manuals and pilot competency tests by CASA official which will cost several thousand up front.

Safety in USA Skies

USA multicopter Flyers be aware - FAA D.O.T USA published an AC 91-57 (Advisory Circular) on June 9 1981 to keep flyers of models away from populated areas (people) and minimise hazard to persons and property on the ground - the intention is conveyed by this AC - It is titled Model aircraft operating Standards - Para 3. a) to e).

Clearly stated are the 400ft height limit and not closer than 3nm from an airport and the avoidance of populated areas and parks.

Once used commercially a model in the USA becomes a U.A.S and pilots should read this document regarding the use of multicopters for Comm Ops
