APC 4" Thin Electric Props 4.1x4.1 (4PCS)

Good quality props

Exactly what I needed. I've been training a new pilot and I need these just in case.

A lot more brittle than they used to be. I dang near buttered a short grass landing after 1 flight with the new prop and it snapped a blade. Glad it’s a 6-pack of em I guess.

Works great and very durable

These things are BITEY. I tested them on an FT Simple Cub (I realize this is not the prop for this airplane) since it's a lot easier to switch things around on and test things out. The amount of thrust these make is actually insane. Pulls more akin to a rocket than an airplane. It was pretty much perfectly balanced as it is. I didn't have to do any additional balancing to get it to run smoothly. It just ran great right out of the bag. Quality is very good - about as good as it gets for PC props. These came with the typical adapters to run on various sized motor shafts. They run like a dream and are very much worth the price tag. They're super stout props.

These are great props. I installed them on my E-Flite Valiant and they work great. They are super sharp and efficient. No complaints

good props
