And it was way out of ballance. I had to machine and grind it just to get it close. **Q: Will this fit my blackjack 24** A: I am not sure. Can you confirm that the shaft diameter is 4mm. You can use it. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Too fast *by on Reviewed in the United States July 27, 2022* I put this on my 24" barbwire XL2 after grinding off part of the tube the blades are mounted on to make it fit. It is bigger than the OEM plastic prop and it made my boat run way faster than it ever has, incredible speed! Afterword when I opened it up the motor smelled like an electrical fire. I don't think I can run this prop very long without burning out the motor. ### ⭐⭐⭐⭐⭐ Works perfect *by on Reviewed in the United States March 14, 2024* Works great on UDI Arrow 5 . 27 mph with a 3000 mah battery going about 6 minutes ### ⭐⭐⭐ Does not fit traxxas m41 *by on Reviewed in the United States April 19, 2022* It wouldn’t fit the shaft size of the m41. Other than that it is great quality. ## Frequently Bought Together - RC Boat 2 Blade Metal Propeller Prop 4mm Diameter P1.4 40mm -Left - uxcell RC Boat CCW/CW Propeller 4mm Shaft 3 Vanes 36mm 1.4 P Fan Shape Pastic Black Rotating Propeller Props for RC Boat Pair - Mxfans Diameter 4mm Shaft Center Hole RC Boat Propeller 2 Blade Brass Boat Parts Diameter 37mm Pitch 1.4 --- ## 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.sg/products/107692977-rc-boat-2-blade-metal-propeller-prop-4mm-diameter-p1](https://www.desertcart.sg/products/107692977-rc-boat-2-blade-metal-propeller-prop-4mm-diameter-p1) --- *Product available on Desertcart Singapore* *Store origin: SG* *Last updated: 2026-09-15*
