Crafted with intricate care and surgical precision, this flight controller is loaded with a Serial ELRS receiver, 4-IN-1 Blheli_S 12A ESC, and a whole suite of other features that make your average flight controller look like a paper airplane. It's designed for Digital HD FPV, making it an excellent copilot for your Tinywhoop, Cinewhoop, Toothpick or any other small FPV drone.

Horrible sizing & inconsistent fit
Size: 27W x 30L, Color: Ecru Booper No Damage
This pant does not fit the same as other colors from the same line/fit. I ordered this color and a light wash 501 90s Jean from Amazon after trying them on at Aritzia and both fit nothing like in store. This color has more fabric in the pocket area, making it wrinkly and unappealing when worn. I am usually. 25” waist (size 2-4 depending on brand), and I had to order a 27” for this to fit around my waist, so size up. I don’t think Levi’s work for curvy girls. I am 125lbs, 5’3”, and an hourglass shape. Levi’s don’t fit comfortably on my hourglass figure, which is unfortunate that such a famous brand still hasn’t perfected a fit for curvy people. The color, thickness, quality, and length were good though, but ultimately returning as it simply doesn’t look good on.

New mom jeans
Perfect Jean for my new postpartum bod! Was sad that none of my old jeans fit. I Was mourning them really-then I decided to just bite the bullet and buy some new jeans in my new size and these are them! They are relaxed enough for me to bend at the knees and not feel like I’m cutting off blood, but fitted enough that I don’t look like a slouch. I could technically have gone a size down and would have liked them but I appreciate some give in this phase of life. For reference I am 5’6 and 129 lbs and I got a 27

So cute and well-made
Great pants made very well, I was hoping they’d be a little longer when I folded them back down at the ankle. But a little too short for me I’m 5’7” which is perfect for us spring and summer, but not going into winter where I live. If you were 5’6” they might be perfect for wearing rolled up or down. It’s a good quality material. They feel very durable in the style is right on!

Great for layering or wearing on its own!
I’m 5’6” and ordered the small — it fits perfectly! The color is exactly as shown in the pictures, a beautiful beige that goes with everything. The fabric is incredibly soft and comfortable, making it great for layering or wearing on its own. I’m really happy with this purchase and would definitely recommend it!
