  • 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.

Quality Design
Color: Gray
Excellent frother/mixer Pros: - Quality feels premium. - Plenty of power to mix even with a drink packed with ice and peanut butter. Basically a mini handheld mixer. - Ease of use is great. I appreciated that this had a longer brother so I can mix drinks in taller cups. Also the grip is fantastic and it is easy very easy to change the speed with just one hand so you can hold the drink with the other. Longevity - So far it's been holding up and hasn't needed a battery replacement. Cons: None so far.

Highly recommend!
Color: Gray
Love this frother!!! Purchased to replace an Aerolatte that stopped working after a reasonable period of use. Right out of the box, it was charged and ready to go. I’ve been using it daily for about 5 weeks on the same charge it had on arrival and it’s still going strong. Love the variable speed and easy to work with one hand. And this baby can froth! It froths far better than our old Aerolatte. Also love the rechargeable feature so no more AA batteries wasted. This handy kitchen tool makes my morning coffee a true highlight. Highly recommend the Maestri milk frother!

Best Frother Ever!
Color: Black
Great little frother and very powerful after just one charge. I haven’t charged it since the first day and it is still going strong after 3 weeks. I use it daily for coffee froth, but have used it for mixing other things as well. It works great on mixing drink powders into water and for making salad dressing from scratch. It’s one of the best things I’ve purchased on Amazon for kitchen tools. My old frother ate through batteries and was 1/10th as powerful. This one really is amazing. Great quality heavy duty but still small machine. Extra attachment heads are also a bonus.

Very good frother that gets the job done extreamly well
Color: White
I hvae used this frother primarily for smoothies and coffees. Each time, it does a wonderful job. Deducted a star for the location of the speed control which is ontop of the device. It's akward to use one handed while attempting to control the speed, athough it's advertised as making it easier. It's not!

Good quality
Color: Black
Have used the frother 5 days in a row. It comes already charged. Fingers crossed no issues when I eventually have to charge it. I love everything about it. It’s worth a little bit of extra money as you can control the blending power from slow to fast. Easily held with both hands to coordinate. Today for a change I elected to just add a touch of bourbon caramel syrup to my oat milk -an excellent choice! They give you two attachments which is helpful. I’m not hard on my kitchen appliances but it’s good to know I have an immediate back up if needed. I rinse frother attachment out immediately in a cup of warm water and air dry on a towel. At this point, I highly recommend. My next adventure in the kitchen will be Matcha tea. I will use the bamboo whisk for the actual tea. If I decide to add oat milk to the top,(such as for a cold latte) I will use this frother.
