The Viper Marine75 is a new brushed speed controller designed specifically for use in RC boats with a battery voltage of between 12V and 15V. The installation, set up and operation of the new Viper marine75 has been designed to be exactly the same as the original Viper range which we have been 'warned' never to change!!
An exciting feature of the new Viper marine75 is addition of Lipo battery pack compatibility as well as the usual NiCAD/NiMH/Lead Acid and Gel cells that are more commonly used.
It has a 75Amp motor limit, what this means is that you can use any, DC brushed motor, as long as the current drawn by that motor does not exceed 75Amps under load (with the prop connected, under water).
The Viper marine75 controller also feature the new 4 quadrant control system that stops the motor completely before turning it in the opposite direction. This allows for perfectly symmetrical operation about the neutral position in both directions, allowing the modeller to achieve perfect slow control in all situations.
Other features of the Viper marine75 controller are the ability to turn reverse on or off. This is done easily by a single press of the set button, allowing you to use the controller in forwards and reverse or forwards only mode and a more powerful BEC, at 2.0Amps the BEC will allow the running of more extras direct from the receiver.
The new marine75 controller is sure to become a popular choice from the line of Mtroniks marine speed controllers and is one that we have spent a lot of time thinking about. The original marine75 controller was a big hit with modellers and when it was withdrawn from our range it did not go down well. The decision to re-work the marine75 was easy, completing the task took longer than we expected but the results are extremely good! The new marine75 is a very powerful, solid, reliable unit that is a worthy replacement for the older version that was liked so much!
All the origianl features are still included, such as a built in failsafe, 100% proportional, fine throttle control in both directions, and motor stall protection, which is a feature that cannot be overlooked when a possible encounter with weeds is always just round the corner. Not to forget it is 100% waterproof and designed to work on either, a fully charged 12V Lead Acid battery, 3S to 4S Lipo packs or between 8 and 12 NiMH cells.
