  • KAVAN R-40SB Plus brushless ESC SBEC 40A 

    New generation of programmable micro processor 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 micro processor ARM M4 with a running frequency of up to 96 MHz.
    • DEO (Driving Efficiency Optimization) Technology greatly improving throttle response & driving efficiency and reducing the working ESC temperature.
    • Suitable for the most of aeroplane model dedicated brushless motors for 3-4S LiPo batteries.
    • Compatible with NiCd, NiMH, LiPo, Li-ion, LiFe batteries
    • Powerful switched UBEC stabilizer 5.0 V up to 5 A.
    • Adjustable timing to match your motor perfectly.
    • Adjustable voltage protection with selectable cut-of 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 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, 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 selected 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 “3.7V/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 2.8V/cell, 3.0V/cell or 3.4V/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 selected this option, ESC will drive the motor chirping prompt when the throttle is kept at 0% and continues to do during the set time.

    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 loss of signal for over 0.25 second, 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 instruction 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.

Adjustable pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
I love these because they don't go flat. You can pull out whatever you need to make them comfy for you. They come in two different layers. So you have that protective cover over the main case that holds the memory foam. They're amazing to sleep on. I have had these last for years without going flat. If you hate flat pillows this is the way to go. They are very easy to wash. You just have to separate layers. They are very thick, you can adjust the thickness. Everyone in my house has at least one. They are worth the money. I have never had to replace them, because they went flat.

Good pillows
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Takes some getting used to but and the cooling doesn’t last very long in my opinion, but overall amazing comfy pillows. The materials are good and are washable. I mostly stopped waking up with a stiff neck and back.

Believe the Reviews
Color: Cooling Blue Cover, Size: King (Pack of 2)
I purchased these pillows because we were in need of new pillows, I previously had allswell pillows which were from walmart and they were good to start but now they tragically became very sparse and it started to effect my sleep so I saw these after careful review on other pillows and reviews I came across these and I saw some reviews and videos and I ordered them.. first they are king size we ordered they are perfect for the bed, they are plump and soft, they are memory foam which has always worked out for me for support and kept it’s shape these are great it did have a little smell I guess from packaging but other than that they are a huge upgrade from what we had before! I’m excited because they are cooling too! for the price point can’t beat it and this is coming from someone who was about to spend money on a purple pillow this will be good for now definitely buy it.

Inconsistent
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
Ive ordered two different batches of these pillows, the first was a 2 pack, the second batch was a 4 pack. The pillows that came in the 2 pack have a different quality to them. The memory foam feels thicker, takes long to depress and to spring back to form. It offers more resistance, a heavier odor (at the start), and was the pillow that I fell in love with. Things changed when I ordered the 4 pack a couple months later. There was an inconsistency between the foam in these two different batches. both sets of pillows are comfortable. The first batch being firmer means I had to remove more foam before it became comfortable but the 2nd batch being more springy, I was able to keep all the foam inside. I docked a couple stars because I’m not able to provide a consistent experience with these pillows across all three beds in my home. If you need a pillow, order a set and be happy. If you want a bunch of memory foam pillows throughout your house, maybe look elsewhere as these may not all be identical.

Very cool and comfortable pillows. Great value.
Color: Cooling Blue Cover, Size: Queen (Pack of 2)
These pillows are everything described on the site. They do retain shape and don’t flatten out after sleeping all night. They are nice and clean looking and comfortable. The fit on my king size bed is perfect cause I prefer the size to king size. Haven’t had to wash them yet but I have had other pillows with the same material inside and the wash ability is great.
