HappyModel X14 ELRS Flight Controller

Let's be honest, the guts of your 2S whoop have seen better days. Enter the HappyModel X14 ELRS Flight Controller, the AIO board that finally crams a proper brain into a tiny package. This isn't just another F4 board with a new sticker; it's a full STM32G473 upgrade with an integrated 400mW OpenVTX and a buttery-smooth 12A Bluejay ESC. If you're building the ultimate 75-85mm toothpick or just reviving a sad, underpowered Mobula, this 2S whoop AIO is the only sensible choice.

Why You Want It

Because your current flight controller has the processing power of a potato and you're tired of watching your video feed turn to static just by looking at a tree. This all-in-one board consolidates your receiver, ESC, and a shockingly powerful VTX, saving you weight, solder pads, and sanity. It's the simplest way to give your micro-drone an IQ boost and a signal that actually punches through walls, all without having to sell a kidney. (We checked, they're not legal tender in the UK anyway).

Dogs loved them, but gone very quickly
Flavor Name: Braided Stick (Chicken)
I picked up these turkey tendon braided sticks as a chew treat for my dogs, and they had zero hesitation. Both dogs were immediately interested and happily worked through them without any convincing. They seem very tasty and easy for dogs to chew, which makes them a nice occasional reward. They seem to be of healthy, quality ingredients, which is always a plus. Similar to some other natural chews I’ve tried, they just don’t last very long with bigger or enthusiastic chewers. What looks like it might be a longer distraction turns into a fairly quick snack in our house. Still, the dogs enjoyed them and tolerated them well, so they work fine as a treat, just not a long lasting chew for large dogs.

Expensive for What You Get
Flavor Name: Braided Stick (Chicken), Flavor Name: Braided Stick (Chicken)
My dogs love chews and I like to try different kinds. I thought they would be longer lasting since they are braided and turkey tendon. These come in a small bag with just a few chews. The chews aren't very big either. They are chewy but not so much that they take a while to eat. I gave one to my 36 lb labradoodle and he finished it in a couple minutes - so it isn't a long-lasting treat at all. At this price point, I would expect more treats or something that lasts a while. My dog loved these but I expect more bang for my buck.

Great braided dog snacks, good ingredients - cost a bit much for the number you get
Flavor Name: Braided Stick (Chicken)
I ordered these Chicken flavored Turkey Tendon Braided Sticks for my three medium sized dogs. I had hoped these would last a little while so gave them one each (there was only like 6 in the pack), but they gobbled them down before I even realized it. They really loved them. I would love to get them these as a special treat every now and again, but they're just too expensive no longer than they last. I know that they're quality treats, made with good ingredients and that really matters, still for no more than you're getting I feel they should cost about a third less. At this rate they're about $3 a piece, and I could get more of some other treat for that price. But if you don't care about the pricing and want only the best for you dogs, then this would be a perfect choice.

Dog chew treat
Flavor Name: Braided Stick (Chicken), Flavor Name: Braided Stick (Chicken)
​I recently purchased these Turkey Tendon Braided Sticks for my dog, and they have been a huge hit. Here are a few reasons why we both liked them: ​High Engagement: My dog was immediately interested and stayed busy with the chew. ​Healthy Ingredients: I appreciate that they are a Turkey Tendon Recipe, which feels like a much healthier alternative to some other chews on the market. ​Quality Design: The braided texture seems to help with the chewing experience and likely helps keep teeth clean. ​I will definitely be buying these again. If you're looking for a treat that is both enticing and made from good ingredients, I highly recommend giving these a try!

My Dog Loves Them, But They Don’t Last Long
Flavor Name: Braided Stick (Chicken)
My dog loves these iPaw Turkey Tendon Braided Sticks, but they don’t last as long as I expected. They keep him entertained for a short while and are tasty enough that he eagerly chews them. The natural ingredients are a nice touch, making them a satisfying treat despite the shorter chew time. Overall, a tasty snack my dog enjoys, even if it’s fairly quick to go through.
