Have tried 3 brands of batteries. Have depressed the key as far as possible. Any suggestions?** A: Just a couple of ideas: 1. If you on use one pair of red and black leads, don't let the other two touch each other. 2. You may have to take the back off and adjust the metal clips that the key makes contact. Mine were slightly loose. 3. I know you said you pushed the key in, but it has to go very far in to make contact. **Q: Can the PS II launch controller be used with small engines and rockets?** A: Oh yes, this is an excellent Heavy Duty launch controller good for any model rocket or Mid Power rocket. **Q: Can this ignite 4 engines simultaneously?** A: Yes. It has two pairs of micro clips and colored wires (red = + / black = -), such that you can light-off two igniters with each pair of micro clips. The launch controller comes with a wiring diagram for doing clusters. This controller is much better than the smaller rinky-dink Estes controllers. Hope this helps. Happy flying!! **Q: Is it tough? I am getting tired of launch controllers dying mid-launch with my classes.** A: I don't get many chances for launches, but I can say that this controller is good. It is far more reliable than the smaller controllers, because of the igniter current available from all the batteries. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great Little Launcher! *by M***T on March 2, 2024* Spent a lot of frustrating hours trying to build my own, threw in the towel and bought a real live launch controller. This one is very nicely made. The plastic case is heavy duty and everything seems high quality and well fitted/designed. Have not actually launched a rocket with it yet but have tested it with an e - match. Price point was good and it works great! ### ⭐⭐⭐⭐⭐ Worth every dollar *by R***S on September 1, 2025* It works very well on my f and g medium power rockets worth every penny I would definitely buy it again. ### ⭐⭐⭐⭐⭐ Great for a full day at the launch site. *by J***Y on February 7, 2026* I like that it uses C alkaline batteries so you launch all day without having to change batteries. Super easy to use, insert the key, press and hold the left button then press the right (launch button) to launch. It has a good weight to it, even without the batteries, it is comfortable and stable to hold. It’s the perfect size for two handed operation. It’s built very well and will last a long time. It is built to launch multiple engines rockets, up to four engines and has the wiring diagrams for two, three and four engines. I still keep my blue pro II series launcher in my tool box as a backup but this is my main launch controller. ## Frequently Bought Together - Estes 2240 PS II Launch Controller, Flying-Rocket-Model Launch Controller, Rocket Model Kit Accessories for Ages 10+ - Estes 2274 Recovery Wadding - Estes 2238 Porta-Pad E Launch Pad,Brown/a --- ## 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.kr/products/8574420-2240-pro-series-ii-launch-controller-flying-rocket-model-launch](https://www.desertcart.kr/products/8574420-2240-pro-series-ii-launch-controller-flying-rocket-model-launch) --- *Product available on Desertcart South Korea* *Store origin: KR* *Last updated: 2026-04-25*
