INTRODUCTION OF K MODES
K1000 Full SubGHz (Coming in ExpressLRS V3.5)
- Yes, you read that right—1000Hz in the 868/900MHz domain! While this mode is designed for maximum data throughput when used with MAVLink, don't let the 1000Hz fool you; during development, it was tested for long-range performance.
DK500 (Coming in ExpressLRS V3.5)
- Designed specifically from the ground up for speed enthusiasts and RC reliability. K modes are next-generation FSK modulation with built-in packet repair (Forward Error Correction). Similar to FLRC D500, DK500 sends repeat packets to minimize packet loss in challenging race environments. Paired with a Gemini-enabled Tx and Rx, nothing compares to its RC reliability.
NEW PACKET RATES
Sub-GHz 200Hz Full (-111dBm)
- Optimized for MAVLink: Double the packet rate of current 900MHz SX1276 hardware, tailored specifically for MAVLink users to provide a more robust link and reduced interference.
Dual Band X100Hz Full (-112dBm)
- Enhanced Gemini Mode: Enjoy dual-frequency transmission with a 100Hz packet rate and full 16-channel resolution, ensuring strong and stable connectivity even in challenging environments.
Dual Band X150Hz (-112dBm)
- Gemini Mode: Experience simultaneous sub-GHz and 2.4GHz transmissions, offering robust performance and reduced interference with a packet rate of 150Hz.
Sub-GHz 250Hz (-111dBm)

Glowy but not sure about the spf
Color: Glistening Bronze
My first impression was that this works more like a basic body shimmer than anything else. The Glistening Bronze shade gives a noticeable glow, especially on arms and shoulders. It spreads easily and adds a warm shimmer in the light, but the overall effect feels pretty simple and more cosmetic than skincare focused.
In use, the oil blends in smoothly and feels lightweight on the skin. It does leave a bit of moisture behind, similar to a light body oil, and the shimmer shows up well outdoors. The bronze tone is fairly deep, so it seems better suited for medium to darker skin tones or anyone who wants a stronger bronzed glow. The product mentions SPF 45, but there is very little information about the sun protection side of it, so I personally treat this more like a shimmer oil than a sunscreen.
Overall, this is fine if you are mainly looking for a body shimmer that adds glow and a bronzed look. It does the job of giving skin a subtle shine and a bit of hydration, but it does not stand out as anything particularly special. I would recommend it mostly for people who want a simple shimmering body oil rather than relying on it for sun protection.

Glamorize your sunny day outing with this shimmer suntan protection
Color: Glistening Bronze, Color: Glistening Bronze
This body shimmer oil has a natural glow luminizer in it. It has an SPF of 45 for sun protection factor. This went on smoothly and easily and was light and did not feel greasy. It felt like fancy suntan lotion like no other I've ever tried before. This just adds a little glamor to your sunny day outing

Glowy, Lightweight Summer Shine
Color: Glistening Bronze, Color: Glistening Bronze
This gives a really pretty sun-kissed glow without feeling greasy or heavy on the skin. The shimmer is noticeable but not over-the-top, and it blends nicely for a smooth, radiant finish. I also like that it has SPF, which makes it perfect for everyday summer use.

This Oil Definitely Glitters!
Color: Glistening Bronze, Color: Glistening Bronze
I really wanted to love this shimmer oil, but it's unfortunately not my favorite. I love that it has SPF! That is a big win for me! The oil is also very good at hydrating my skin, which I appreciate. My problem comes with the shimmer of the product. The glitter in it is too big for my liking. With it being called a shimmer oil, I expected tiny glitter that softly shimmers like shimmer powders, lotions, and oils usually do. But this stuff glit-ters! And because it's bigger sized glitter, it's a lot easier to see when it gets all over everything like clothes, furniture, spouses and children. If the shimmering glitter in this was just smaller and softer, I would love this for summer time to use on my legs and arms. But it's unfortunately just not my favorite and I don't think I'll be using it anymore.
