Thunderbird 9 is capable of 3S LiPo with a 1.5 amp peak BEC, and is ideal for lightweight and mini indoor or outdoor planes with very small power needs.
All Thunderbird controllers are ready to fly straight from the package, no programming necessary.
They are defaulted to Auto LiPo detect and no brake.
Should users wish to modify these settings, they may do so using their transmitter or with Castle’s incredible Castle Link USB Programming Kit (sold separately).
Note: Thunderbird controllers are not for use in helicopters.
