Rubber Band Propeller Kit, STEM | Ten plastic propellers for rubber band helicopters, planes, cars, and classroom STEM builds: Propellers - desertcart.com ✓ FREE DELIVERY possible on eligible purchases Review: Great - Bought to make a school project. They fit perfectly on a popsicle stick. And worked perfect.they are very durable .Will buy again. Review: Peppy little propellers - I used these propellers to make helicopters with kids. When they didn’t break they worked awesome. I found if you put a lot of tension on the rubber band the propeller would snap between post and hooks holding piece. Also, the fit on a popsicle stick is pretty snug which is great to ensure it stays on but it also has broke on me because I put too much force on the wrong part of the prop. So, as long as it is not overwound and your careful placing on the stick then these are a great deal. The really do work well and made the helicopters fly far. I made 1 rubber band plane and it flew better than a store bought. I would buy these again. ## Features - Designed for STEM Projects: This 10-pack of 6-inch plastic propellers is specifically engineered for rubber band-powered creations, including model airplanes and planes, helicopters, and propeller-driven cars. - Easy to Use: The propeller assembly mounts securely onto standard craft sticks, popsicle sticks, or balsa wood measuring up to 0.135 by 0.35 inches, providing a reliable foundation for building. - Directional Thrust Control: Featuring a built-in propeller shaft with a small hook for rubber bands, the design only permits winding in one direction. This ensures the generated thrust consistently moves your project forward. - Adjustable Performance: The propellers generate substantial lift and thrust. Builders wind up a single rubber band for a slower, sustained energy release, or double the rubber bands for a quicker, more powerful burst of energy. - Durable Materials: Constructed with high-quality steel and semi-flexible plastic. The plastic blades are resilient enough to withstand minor to moderate impacts, while the steel shaft resists bending during normal use. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B06X3Q8C24 | | Age Range Description | Kid | | Best Sellers Rank | #117,380 in Toys & Games ( See Top 100 in Toys & Games ) #121 in RC Vehicle Propellers | | Brand Name | STEM Inventions | | Customer Reviews | 4.2 out of 5 stars 170 Reviews | | Educational Objective | STEM | | Item Dimensions | 7.01 x 2.99 x 0.98 inches | | Item Highlight | Ten plastic propellers for rubber band helicopters, planes, cars, and classroom STEM builds | | Item Weight | 4.54 g | | Manufacturer | STEM Inventions | | Manufacturer Part Number | 43234-1307 | | Manufacturer recommended age | 0 - 10 years | | Material Type | Plastic | | Model Number | 43234-1307 | | Number of Items | 10 | | Set Name | 1 set | | Size | Small | | Theme | Vehicle | | UPC | 631912022363 | | Unit Count | 10 Count | ## Images ![Plastic Propellers, 10-Pack - 6 in.

Two rubber bands usually works best! **Q: How many propeller are in one pack? And how many pack is being given here in this order?** A: There are 10 propellers in a pack. If you order one of this item, you'll receive one pack. **Q: Just to be sure, $14.94 its for 10pieces of this 6inch propellers right?** A: Yes, that's correct. **Q: What kinds of plastic is this made from?** A: I am not positive but these worked great for our classroom to make propeller cars. Much more sturdy than the propellers we used previously. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great *by B***. on November 18, 2024* Bought to make a school project. They fit perfectly on a popsicle stick.

The propeller just snaps onto a popsicle stick. The only other supplies you need to make a helicopter are: rubber band, paper clip, tape, and construction paper. There are several YouTube videos out there on how to do this. After a few trial and errors, my six-year old made some helicopters that went at least three stories. ## Frequently Bought Together - STEM Inventions 6-Inch Plastic Propellers, 10 Pack - Build Rubber Band Airplanes, Helicopters, and More - Fits onto Craft Sticks and Balsa Wood - Toy Wheels - Bulk Pack of 100 - Small Plastic Wheels for Toy Cars, STEM Projects, Crafts, Mini Vehicles --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.ar/products/40172714-plastic-propellers-10-pack-6-in-rubber-band-propeller-kit](https://www.desertcart.com.ar/products/40172714-plastic-propellers-10-pack-6-in-rubber-band-propeller-kit) --- *Product available on Desertcart Argentina* *Store origin: AR* *Last updated: 2026-09-07*
