Get maximum power and maximum control with CSM's RevLock engine governor! RevLock locks your engine RPM to a pre-set speed for the smoothest hovering conditions, unrivalled rotor speed retention in aggressive 3-D flight, and maximum engine power and gyro gain.

And because CSM RevLock is the only engine governor to use a digitally synthesised 'virtual engine' reference, it gives the most accurate RPM every flight - with no need for a tacho.

Also recommended for beginners! RevLock reduces the need to alter throttle curves, and protects your equipment from over-revving. CSM's Linear Hall-Effect sensor works with the magnet fitted either way around, and ensures the simplest possible set-up.
