The flight controller adjusts the rate of spin to keep your quad level. Theoretically you should be able to change one motors and the controller will stabilize even if these are faster than the original. The stability of the quad will depend on the controller's processing power and it's ability to quickly adjust. If there is a large speed variance between this and the original motors, it is possible that the controller may not be able to fix this quickly enough for stable flight. Additionally you don't want to mix new motors with old. The brushes on the motors wear with time... Your best bet is always to change all for for best performance. **Q: Will these work with mini diy hovercraft?** A: They should. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great little motors! *by J***N on November 20, 2019* I used one to replace the tail motor/prop on my Extreme S-8G helicopter. The original motor and propeller blades are more than 2 times the size so I thought I would have to use 2 of these to move enough air but these are very powerful little motors and well shaped/designed props! In fact just one of these moves much more air than the original ones do and weigh much less too, the original weighs 15 grams and these weigh just 6 grams, and every gram of weight removed improves the helicopters performance, so I'm very happy and impressed with how well they work..And I have 3 extras for back-up too! ### ⭐⭐⭐⭐ Hard time pairing them with a good ESC *by A***R on January 24, 2024* These motors seem like the perfect fit for a little RC plane. I’m having trouble finding a proper ESC for a small brushed motor like this. I bought a small 1A speed controller but it seems to brown out as soon as I’m on half throttle. If anyone knows a good ESC for a small plane please comment. ### ⭐⭐⭐⭐⭐ These are some strong motors. They worked well for ... *by S***. on May 30, 2018* These are some strong motors. They worked well for a stove fan project. Connect them to a AA battery and it's scary how fast they turn, and that's not even their full rated voltage. --- ## 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.jp/products/41156439-set-of-4-usaq-8520-coreless-brushed-motor-8-5x20mm](https://www.desertcart.jp/products/41156439-set-of-4-usaq-8520-coreless-brushed-motor-8-5x20mm) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-11-12*
