Viper Marine40
Click image above to enlarge
The Viper Marine40 is a Brushed Speed Control designed specifically for use in RC boats.
The Marine40 has a 40Amp 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 40Amps under load (with the prop connected, under water).
The Marine40 is the perfect speed controller for anybody wanting to either upgrade their old Speed Controller for a no nonsense 40Amp limit reversible electronic Speed Control or for anybody who uses anything from scale model RC boats at scale speeds to scale speed boats.
The Marine40 is the highest powered marine speed controller in the Viper range of Speed Controls suited to RC model boats, which means it has all the same features as all the other Viper marine speed controllers but with more power! It also has everything you would expect on a more expensive Speed Control! Features such as a built in failsafe are standard on Marine40 and the motor stall protection is a feature which cannot be overlooked when a possible encouter with weeds is always a possibility.
One difference to note between the Marine40 and the others in the marine range is that the Marine40 comes with user solderable posts instead on pre installed wires. This gives the user the option to use their own wiring looms!

Set up hints and tips for the Viper marine range of controllers, FAQ
Q, When I switch on I get a solid red light?
A, Check that the speed controls receiver lead is plugged into channel 2, not the batttery slot.
Q, Motor runs at full speed reverse when pairing 2.4G transmitter and receiver?
A, On most 2.4G systems there is a built in failsafe that sets a position for the throttle during failsafe, with flight type transmitters this is generally full back stick. In a forwards and reverse application (model boat) this needs to be reset to mid stick point (Refer to transmitter manual). The speed controller will only do what it is told by the transmitter, ie, the speed controller does not know the reciever is in failsafe mode. It will recognise this signal as a valid signal and respond accordingly. The speed controllers internal failsafe operates if there is excessive noise or an invalid signal only.
Q, Throttle goes dead at the end of the stick travel after I set the controller to my transmitter?
A, This is due to the output range of the transmitter going beyond the range that the Viper will recognise. The solution is to set the E.P.A. (end point adjustment) to 70% on the throttle channel and then reset the speed controller. This situation is similar to a rudder which travels too far, you reduce the E.P.A. to 'tune' things to work over a suitable range. If your transmitter does not have adjustable E.P.A. please contact Mtroniks.
What are we doing about this? (Honest answer!) - The new 'tio' range of marine controllers adjusts this range automatically, we can't do this with the Viper controllers due to limitations in the processor memory.
