This is the Estes Mini Mosquito Rocket Kit. The Mini Mosquito is a mini engine powered version of the 1335 Mega Mosquito. Standing just 3.8 inches tall, this little guy can really sore! The Mini Mosquito features simple and quick construction with out of site performance. When powered by the A10-3T mini engine, heights of 800 feet can be reached. That's more than 200 times its own height! Tumble recovery brings this awesome little rocket back to earth. But buyer beware, with the rocket being so small and using the most powerful mini engine Estes makes, it might not return...Consider yourself warned!
