  • Electric
  • The engines typically used to be methanol-powered two-stroke motors, but electric brushless motors combined with a high-performance lithium polymer battery (LiPo) are now more common and provide improved efficiency, performance, and lifespan compared to brushed motors, while decreasing prices bring them within reach of hobbyists.

  • application
  • Because this question gets asked so much, I've summarized my care guidelines for extending LiPo lifetimes when used in an R/C application. (barnson.org)
