The Quickstart electric motor spins the gyroscope effortless up to an impressive 12,000 revolutions per minute. The motor can be fastened to the gyroscope with two screws providing hours of continuous use or it can be used to briefly start it and quickly detach, allowing you to perform experiments for as long as 25 minutes (depends on experiments).
The electric motor makes it easy and quick to start gyroscope, with speeds you would struggle to achieve with string pull start. The motor has its own battery pack that requires 4 AA batteries. Batteries are not included.
