  • Crafted for advanced pilots, the ultra-thin (0.8mm) and lightweight Air FC is engineered for maximum agility and race-winning performance. It is the definitive choice for pushing the boundaries of FPV flight.  For newcomers to FPV or those flying for entertainment, the Matrix FC is the ideal alternative. It offers enhanced durability, requires no welding, and provides a more beginner-friendly experience.
  • VTX Power: Higher VTX power consumes more energy and generates more heat, reducing flight time. For better flight time in indoor scenarios, use 25~100mW power. 
  • The calibrated power measured after temperature stabilization (stabilization condition: more than 60 seconds after powering on the flight controller) is: when set to 25mW, the output power is between 14dBm±0.8dBm (21mW to 30mW), which meets the normal standard. The following is the 5IN1 Air FC test data with the VTX set to 25mW, the power data is tested at different times on the R1, R3, R5, and R7 frequency points.
  • Motor Wiring: Only soldering is supported for motor wiring on the flight control. Be careful to ensure the temperature of the soldering iron is maintained below 370℃ and limit the soldering duration to 1~2 seconds.

Best dog ball
This is our go to dog toy for our German shepherd. its great for training in sports as well as outings at the beach, considering it floats! Never had him destroy one, so its extremely durable. I like that its a bright color so its easier to locate when i accidently let go of the rope too late and end up whipping it 20 ft into the woods. Easy to clean, all around just a great toy. Also love the large size as having a dog accidently lodge a ball into its throat is a real fear of mine, I do not have to worry about that with this toy. I should also mention the rope is a must, as touching a slobbery ball isn't the greatest feeling in the world and it puts your hands out of harms way. I will forever order these.

Great ball, bad rope
Size: Medium, Number of Items: 1, Size: Medium, Number of Items: 1
My dog and I love the starmark ball on a rope tug toys. While this is one of the best tug toys we have found, I am continually disappointed with the quality of the rope. The plastic sleeve comes off the first day, and after that the stitching begins to weaken until the rope ends come apart and the rope slides out of the ball. Is there a way to improve this design so that this toy lasts longer? My dog is not left alone with the toy, it is only used as an interactive tug toy as a training reward. I am updating my review now several months later. I reinforced the rope with a paracord braid and the toy now lasts a very long time. My dog and I play with this toy everyday on our morning hike. He is a large German Shepherd with high ball drive. He carries this ball in his mouth several miles on our morning hike. We play fetch in the fields near our home and in the lake beyond the fields with this toy every day. This toy is his reward in obedience training and we play a lot of tug with it every day. Reinforcing the handle has made a huge difference as the toy lasts and lasts now with the improved rope. Great ball, we will always have a collection of them at our house!

Great for big dogs
Size: Medium, Number of Items: 1
Our pup is now 15 months old (nearly 110 lb and still growing). We got this ball when he was 3 or 4 months old. GOODS - - Our pup fetches with extreme drive, and the rope helps him quickly snatch the ball off the ground (versus a tennis ball, in which we are worried he will go head over heels at times) - Our pup also loves to play fetch in the water, and this ball floats great and again, the rope gives another point to bite onto - The yellow color is easy to see, even in grass - Our pup typically fetches the ball, and leaves the rope mostly out of his mouth. So, throwing the ball doesn't result in saliva-covered hands - It's pretty easy to throw the ball 50', and possible to throw it 100' - It doesn't roll/bounce, so if you are for example playing fetch on your front lawn and are concerned with a tennis ball rolling into the street, this one alleviates that issue - Our pup is spoiled and has several balls. This is absolutely his go to ball. We have woken up in the morning before to see him standing next to the bed with the ball in his mouth, asking us to get up and play. BADS - - Occasionally when he goes to fetch it, he will step on the rope as he tries to pull up on the ball. - We have gotten this ball stuck in trees multiple times. In fact, there is one stuck on the roof of our church from playing fetch on the lawn there. :-/ Not a fault of the ball, but if you start whipping it around like nunchucks, it might not go where you want. - The near max you can through this ball is 100'. And since it doesn't roll/bounce, throw distance is throttled. We often play fetch in a local baseball field, and have no issue wearing him out with this ball. However, if you are planning on throwing a ball the distance of half a football field, you might want to consider something else. SIZE - - We purchased both the medium and the large. Even though our pup is huge and can fit a soccer ball in his mouth, he still prefers the medium. It's easier for him to get in his mouth and breath while running back. The medium is the size of an orange, whereas the large is the size of a grapefruit. DURABILITY - - We have gone through about 4 of these balls, BUT this is because we lost 3 of them. We believe he dropped one out of the car window while we were driving, one is on the roof of our church, and I forget about the other one. On the first one we had, the stitching behind the black tape was down to a few threads after about 5 months. Given duration we use these balls (every day) and the joy he gets from them, I feel the durability is good for the price. - We do play tug with the ball at times, and no issues there Enjoy!

Good but better options out there.
Good ball, but is a cheaper version of the Foamster sold online. The rope is cheap and comes apart, and can be abrasive to a dogs mouth. The Foamster uses a higher quality ball and are more durable and use grippy biothane straps rather than cheap rope. They are also made to order in the USA with lots of fun colors. Worth the extra money if your dog likes these balls.
