Mtroniks Marine Speed Controllers
The Mtroniks Viper Marine electronic speed controllers (ESC) are waterproof, and are designed not to have the 50% reverse power (as some earlier models did). We are now stocking all of the following speed controllers. All of the marine speed controllers (Viper, tio, and Hydra lines) are completely waterproof as the electronics are potted in epoxy.
We now stock the bullet connectors that are perfect for the output connections of the ESC. The connectors are located on our hardware page.
In the various versions of model warship combat, the vast majority of ships run brushed motors. They are less expensive though not as efficient as brushless. Brushed motors also have the advantage of being able to have two motors in parallel running from a single speed controller (or even simple forward and reverse switches). Each brushless motor requires a dedicated speed controller.
Brushed Speed Controllers:
All of the brushed speed controllers are designed to operate on 6 to 12 volts nominal (fresh sealed lead acid batteries are about 13.2 volts, which is ok) except for the Viper-10 which can be as low as 4.8V. These models all have a 1.2 amp BEC (battery elimination circuit) which should negate the requirement for dedicated battery for the radio and servos except for the Viper-75 has a 1.5 amp BEC. The Viper 40 and 75 controllers require a small amount of assembly before use: the power and motor wires need to be soldered onto posts coming out of the speed controller (the wires are included). This was done so that people could attach custom cabling if they so desired. Attaching the included wires only takes a few moments with a soldering iron.
The tio Marine line of speed controllers is new with Mtroniks. They have new electronics for stopping the motor before running it in reverse, and the reverse can be disabled.
Brushless Speed Controllers:
|SPEED-HYDRA-15||G2 Hydra 15||$85.00|
|SPEED-HYDRA-30||G2 Hydra 30||$100.00|
|SPEED-HYDRA-50||G2 Hydra 50||$135.00|
We picked up a limited number of brushless speed controllers for those that want to test them out (including us). The Genesis G2 Hydra line of brushless speed controllers are designed for 6V to 12V nominal, but come with a 3.0 amp BEC. The Hydra line also has what Mtroniks refers to as ‘return to base’ software updates. They have a way to update the firmware in the ESC if it is sent to them. They will post notices in the news section at www.mtroniks.net. The Hydra line of speed controllers are reversible, unlike many brushless controllers.
Currently, we envision the brushless speed controllers and motors being used for pumps and ships with an odd number of props like the Bismarck.
