The 900 series is a further development of the proven ROXXY BL-800 series, and now offers a range of new functions which make these speed controllers equally suitable for use in model aircraft, boats and electric helicopters.

The new functions:
Programmable forward / reverse function, ideal for model boat applications.
Governor mode, optionally programmable with or without speed regulator: perfect for micro and mini electric helicopters.
Plug-in programming card for simple and unambiguous function set-up.

Additional features:
Can be set for use with in-runner and outrunner motors; LED indicator.
Brake can be programmed on and off.
High pulse frequency (32,000 Hz) for ultrafine speed control, e.g. for ""torque-rolls"".
Integral temperature guard protects the controller from thermally induced damage.
Designed for 6 .. 12 NC / NiMH or 2 ... 4 LiPo cells.
Programmable low-voltage cut-off.
Like all robbe speed controllers, these units are fitted with the usual protective and filter functions, including POR power-on guard and RX filter.
Designed specifically to match the ROXXY series of BL motors, but can also be used with other brushless motors.
