Both new Thunderbird controllers feature automatic lipo detect cutoff right from the package! Just plug in and and fly your lipos safely with no programming needed (or change the setting to fly NiCad/NiMH)!

Only Castle Creations can bring you this level of consistent quality and proven design for a price this low! Plus, it's backed by a full one year factory warranty, and supported by the company that set the standard for customer service in the hobby industry.
