  • KAVAN R-120SB Plus Brushless ESC SBEC 120A
  • New generation of programmable microprocessor electronic speed controllers KAVAN Plus for brushless sensorless motors designed using the latest achievements of the semiconductor technologies ensuring high performance; whilst still being simple-to-use/user friendly. The Plus line ESCs will work great in any of „Sunday flyer“/sporty model planes powered by brushless motors using LiPo/Li-ion/LiFe as well as NiCd/NiMH batteries. The ESC features a powerful switched UBEC ensuring reliable power supply for your receiver and servos. The optional KAVAN LED programming card Pro (sold separately; the same as for the KAVAN PRO ESC line) will make the programming of your ESC a breeze.

    FEATURES

    • The ESC features a high performance 32-bit microprocessor ARM M4 with a running frequency of up to 96 MHz.
    • DEO (Driving Efficiency Optimization) Technology greatly improves throttle response & driving efficiency and reduces the working ESC temperature.
    • Suitable for the most of aeroplane model dedicated brushless motors for 3–8S LiPo batteries.
    • Compatible with NiCd, NiMH, LiPo, Li-ion, LiFe batteries
    • Powerful switched UBEC stabilizer with selectable output voltage 5.0/6.0/7.4/8.4 V up to 10 A.
    • Adjustable timing to match your motor perfectly.
    • Adjustable voltage protection with selectable cut-off type (soft cut-off/hard cut-off).
    • Start-up Modes Normal/Soft/Very Soft to match direct drive as well geared power systems
    • Start-up protection prevents the unintentional start of the motor when powered up.
    • A number of protection functions: start-up protection, ESC thermal protection, capacitor thermal protection, overload protection, over current protection, abnormal input voltage protection and throttle signal loss protection contributing to safety operation.
    • Throttle range calibration to match your radio set signal.

    PROGRAMMABLE FUNCTIONS

    • Brake Type: Normal brake off, Normal brake on (3 brake force levels selectable), Reverse brake (the forward/reverse run is selected by an auxiliary channel with 2-position switch on your transmitter, the revolutions are controlled by the throttle stick, Linear reverse brake (the reverse revolutions are controlled by a proportional control assigned to an auxiliary channel on your transmitter)
    • Brake Force: Brake force adjustable to 60/90/100 % (Normal brake mode only).
    • Voltage Cut-off Type: Soft Cut-off: After selecting this option, the ESC will gradually reduce the output to 60 % of the full power in 3 seconds after the low-voltage cut-off protection is activated. Hard Cut-off: The ESC will immediately cut off the output.
    • LiPo Cells: The ESC will automatically calculate the number of LiPo cells you have plugged in as per the “3.7 V/Cell” rule if “Auto Calc.” is selected, or you can set this item manually.
    • Cut-off Voltage: If set off, the low-voltage protection function is disabled. If on, the protection voltage threshold is selectable at 2.8 V/cell, 3.0 V/cell or 3.4 V/cell.
    • Start-up Mode: This is used to adjust the throttle response time of ESC acceleration from 0 % to 100 %. Normal/Soft/Very Soft correspond to approximately 200 ms/500 ms/800 ms respectively.
    • Timing: Adjustable to 5/15/25 °.
    • Active Freewheeling (DEO): This item is adjustable between “Enabled” and “Disabled”, and it is enabled by default. With it enabled, you can have better throttle linearity or smoother throttle response.
    • Search Mode: After selecting this option, ESC will drive the motor chirping prompt when the throttle is kept at 0 % and continue to do so during the set time.
    • BEC Voltage: Selects the BEC output voltage 5.0/6.0/7.4/8.4 V.

    PROTECTIVE FUNCTIONS

    • Start-up Protection: The ESC will monitor the motor speed during the start-up process. When the speed stops increasing or the speed increase is not stable, the ESC will take it as a start-up failure. At that time, if the throttle amount is less than 15%, the ESC will try to restart automatically; if it is larger than 20%, you need to move the throttle stick back to the bottom position first and then restart the ESC.
    • ESC Thermal Protection: The ESC will gradually reduce the output to 60% but won’t cut it off when the ESC temperature goes above 120°C (soft cut-off mode)/the ESC will shut the motor off (hard cut-off mode).
    • Throttle Signal Loss Protection: When the ESC detects a loss of signal for over 0.25 seconds, it will cut off the output immediately. The ESC will resume the corresponding output after normal signals are received.
    • Overload Protection: The ESC will cut off the power/output or automatically restart itself when the load suddenly increases to a very high value.
    • Low Voltage protection: When the battery voltage is lower than the cut-off voltage set by the ESC, the ESC will trigger the low-voltage protection. If the battery voltage is set to soft cut-off, the battery voltage will be reduced to a maximum of 60 % of the full power. When set to hard cut-off, the output is cut off immediately.
    • Abnormal input voltage protection: When the battery voltage is not within the input voltage range supported by the ESC, the ESC will trigger the Abnormal input voltage protection, ESC will drive the motor to sound the alarm.

    Tip: Turning the ESC on for the first time: Perform the throttle range calibration following the instructions in the manual. Only then you can use the ESC normally or you can set the programmable parameters using your transmitter or the KAVAN LED programming card PRO.

Truly indestructible!
My 80lb English bulldog, that literally can chew his way through a tree trunk if left to his own devices, has not been able to destroy this toy. Rather, he’s enjoyed chomping on it bc of the scent and heavy weight for more than a year. Good value and will hopefully last many more years.

Nice toy
Flavor Name: Peanut Butter, Size: Large
I bought this toy in L size for my Frenchie cuz he is a hard chewer, and it ended up being too big for him. He seemed to love it though. I’ll reorder a smaller size

The warnings on the box say it's dangerous, the product page said it was safe.
Besides being much smaller than expected, this is from the box: + It's important to select the proper size & type of chew for your dog's age, weight & chewing strength. - "The Amazon page says it's 'Safe for All Dog Sizes.'" + Always supervise the use of all chews & toys - "The Amazon page says 'a safe alternative to edible chews when you can’t be home.'" + Product is not intended to be eaten or ingested. If you think your dog swallowed a piece, take the product away and contact your veterinarian. - "The Amazon page says it 'provides a safer alternative to real sticks. Safe non-toxic. A safe alternative to edible chews when you can’t be home." I've been disappointed by Amazon purchases before, but this is the first negative review I've written because this thing seems dangerous for dogs. I would report it to Amazon, but I can't figure out how.

It's not for aggressive chewers.
Flavor Name: Peanut Butter, Size: Large
The bone looks solid except for the brown strip wrapped around it. My dog chewed a piece of it off and tried to swallow them. I had to pull two strips of hard plastic out of his mouth. I threw the bone away.
