This product incorporates the latest technological developments. You have got a very efficient controller for brushless motors use. Our priority was reliability and simple to use. All SWIFT 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. Even if programming sequences of SWIFT speed Controllers are particularly logical and therefore very easy, using and operating requires some knowledge and a few basic skills. Please read through instructions entirely before attempting to operate with these electronic devices. High power system for RC model can be very dangerous, so we strongly suggest you read this manual carefully.
