Fettec FETtec ESC 4in1 45A (3-6S)IMPORTANT NOTE: Fettec have advised that the active current limiting feature will not protect against burst current. We recommend that motor propeller combinations used with this ESC draw no more than 35A continuous, as blown MOSFETs will likely not be covered under warranty over this current limit. This is the second ESC released by FETtec. This ESC supports both KISS and Betaflight and runs at Dshot 2400. It supports 3 6S input and if running on 6S,

This is the second ESC released by FETtec. This ESC supports both KISS and Betaflight and runs at Dshot 2400. It supports 3-6S input and if running on 6S, it also has direct mounting options to add capacitors to ensure your circuits are running clean. Bottom line this is one awesome ESC to get the most out of your motors.

Works great with the FeTtec Kiss F7 FC

What is Full Sine Wave Control?

Most ESC control the FETs by simply turning them on and off which works, this means the power change as the current moves form one phase of the motor to the next is very abrupt (image below left graph). This effect is what causes the whining on brushless motors. A sine wave controller on the other-hand, still uses FETs to control the current to various phases in the motor, but the power change is applied smoothly (image below right graph).

This shirt checked all the boxes, comfort, fit and feel.
Size: 3X-Large, Color: Teal 02, Size: 3X-Large, Color: Teal 02
OMG! what a nice shirt. The pattern is awesome and the material is very soft and light weight. It is so breathable. Material has a bit of stretch so it very comfortable sitting or standing and does not wrinkle. I will be ordering at least on more in another color

Surprisingly awesome. Seriously. And I hate buying clothes.
Size: X-Large, Color: Black
I'm 6'1", 215 with large shoulders and chest. "Athletic dad-bod." Nothing fits me perfectly. I'm constantly stuck between an XL and XXL shirt, and a 37x31 pant---so literally nothing fits me and if you're a big guy, we all know that most polo shirts look like crap and fit like garbage bags. The shiny tone first made me skeptical. I wasn't even going to take it out of the package. But for $19, I said screw it. It fits really well. Not slim fit, but not "Ralph Lauren trash bag regular fit." It's soft like textured silk. It looks good and is the perfect length if you're 6'-6'3. And no--I know your first thought with the texture and shine is "does it look like a cheesy club shirt on a NJ Italian guy?" Shockingly, no...it's actually really nice (yeah--I had the same thought). It's stretchy. It's relatively form fitting, and it's cool to the touch. I immediately bought 3 more. For $19--just buy it. You won't regret it.

Good shirt
Size: Medium, Color: Teal 02
Love the color and the design of the shirt. The small threads it’s made out of starting to come loose though. Now when look down at chest and stomach area, there are 15+ little strings that pop out of the shirt.

Awesome shirt!
Size: Medium, Color: Blue, Size: Medium, Color: Blue
This is a nice shirt! Let me start by saying I am 6 foot 2, 195pounds with about a 40 inch chest, 42 inches on a good day! Ha ha. I ordered a medium because I wanted an athletic fit. The medium fits just right. For those wanting a normal, roomier fit I would recommend the large for my size. I’ll get a lot of compliments when I wear this shirt. What I like about it is that it is wrinkle free and looks great, I would not wear it on a super hot day with a snug fit. I do live in Florida, so that makes a difference. I also ordered the black one, both the blue and the black look very good for dress /casual. It’s polyester so it’s not super soft, which is OK. That also means it does not shrink.
