REVLOCK:
a quantum leap in engine control
Get maximum power and maximum control with CSM's RevLock engine governors! 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.

Available in four versions to suit all budgets and all flying styles:
RL10 - simple governor, ........RL20 - governor/limiter
RL30 - Collective management governor, ...RL40 G-sensitive Collective management
Upgrade from RL30 to RL40

RevLock RL30

Takes helicopter governors to a new level with Collective Management, another innovative performance-enhancing idea from CSM.

RL30 has all the accuracy, ease of installation and flexibility for which RevLocks are renowned. But now, when you reach the limits of the power output of the engine, RL30 automatically modulates the maximum collective pitch available to prevent the engine becoming bogged down.

With RL30 your can use more collective pitch range than with a conventional governor. You get higher flight speeds and snappier transient high g manoeuvrability. In sustained high g and high cyclic situations RL30 almost imperceptibly regulates the maximum collective pitch to keep your engine in the power band leaving you to concentrate on the flying.
RevLock 30
Size 30 x 35 x 4 mm
Weight 9g
As with all RevLocks, RevLock 30:-
  • Protects your equipment from over-revving
  • Locks to a digitally synthesised reference: gives the greatest accuracy and fastest response
  • Maintains power and control in aerobatics
  • Ideal for beginners: easy to installl and helps with throttle curve setup
  • You’re in control: switch modes and alter speed and responsivity from your Tx.
  • Like RevLock 20, is adjustable via PC Interface: set parameters from home or your laptop, compatible with the CSM LPT and USB PC interfaces
Supplied with sensor, magnet, three stainless steel mounting brackets, three 300 mm leads, mounting foams, adhesive heat-shrink sleeving, pot adjuster.

CSMRL30........RevLock 30........RRP 55.95

Requires a PC interface to access all features, and a mixer such as CycLock to be able to allow the full Collective Management feature to be used on CCPM models: see Spares page

RevLock RL40

Advanced G-Sensitive Collective Management.

Now there is no need to compromise your set-up between high-g capability and ultimate climb and flight speeds. RL40 intelligently applies collective management to give you the best of both worlds.
Like its predecessor, the RL30, this governor will, when needed, limit the amount of collective pitch available to prevent excessive loss of head-speed in high-g manoeuvres. However, RL40 goes one stage further, and by incorporating an accelerometer is able to recognize low-g flight situations such as fast forward flight and vertical climbs where greater performance can be obtained by allowing more collective pitch to be employed even where this results in some loss of head speed.

It also greatly simplifies the set-up and installation by removing the need for careful pitch range adjustment.
As with all RevLocks, RevLock 40:-
  • Protects your equipment from over-revving
  • Locks to a digitally synthesised reference: gives the greatest accuracy and fastest response
  • Maintains power and control in aerobatics
  • Ideal for beginners: easy to installl and helps with throttle curve setup
  • You’re in control: switch modes and alter speed and responsivity from your Tx.
  • Like RevLocks 20 & 30, is adjustable via PC Interface: set parameters from home or your laptop, compatible with the CSM LPT and USB PC interfaces
Supplied with sensor, magnet, accelerometer head, three stainless steel mounting brackets, four 300 mm leads, mounting foams, adhesive heat-shrink sleeving, pot adjuster.
