Multi Rotor 25A ESC Expansion Pack, without BEC, by Castle CreationsWhether you’re upgrading to a higher payload AP/FPV platform and need to add a rotor or two, just getting into multi-rotors and require more ESCs than our QuadPacks offer, or just looking to have a fully customized multi-rotor, Castle’s new Multi-Rotor Expansion Packs are the answer. Both the 25 and 35 amp versions are available individually packaged with and without BEC capability allowing you to customize your multi-rotor to your specifications.
The small footprint and lightweight design make them the perfect solution for smaller multi-rotor applications. The lightning fast 490 Hz refresh rate provides stability during even the most extreme maneuvers. While the Multi-Rotor 25 & 35 Expansion Packs come pre-programmed for multi-rotor applications, they also offer industry-leading so^ware functions and USB programming capability via Castle Link USB adapter should you require them (Castle Link sold separately).
