Maker Hangar is a 15-part video series by Lucas Weakley.

In Episode 4 of the Maker Hangar series, Lucas Weakley teaches us about lithium polymer, or li-po, batteries, used in R/C aircraft. Lucas covers the numbers and letters that classify these batteries, how to determine where to place the battery for balancing the plane, charging the batteries, and safety concerns.


MAKE and Lucas Weakley have teamed up to bring you Maker Hangar, a 15-episode tutorial series that will teach you everything you need to know to build and fly this custom RC plane, the Maker Trainer.

New installments will air every Tuesday and Thursday through August. Also, be sure to join us on the Maker Hangar Google+ Community page to share your ideas, comments, photos and video and details for your own RC plane project builds.

Lucas Weakley is a 17-year-old Eagle Scout who will be a senior next year in the Engineering and Manufacturing Institute for Technology (EMIT) at Forest High School in Ocala, Fla. Lucas became interested in flight and got his first RC plane for his ninth birthday. Recently he’s been designing and building his own planes and hosts an R/C aircraft YouTube show called BusyBee TV. Lucas also has his own aerial videography company called TopView Aerials.
