The G2 Hydra50 has a 50Amp Brushless motor limit, this is a rough equivalent to a standard, stock 600 can Brushed motor. The G2 Hydra50 Brushless speed control has been designed to fit straight into any RC model boat as a direct replacement for your Brushed speed controller. The set up is a no nonsense, one-step procedure making it very easy to get up and running within minutes! The G2 Brushless Speed Controls designed for use in RC boats are all 100% waterproof giving you that extra peace of mind should the worst happen and you have to retreive your model from the graveyard under the pond!! The G2 Hydra50 benefits from 5 years worth of research and design work carried out by the Mtroniks design team with help from a few well known RC scale sailors. What this has resulted in is a Sensorless Brushless Speed Control that works and feels just the same as a Brushed Speed Control, giving you absolute control over the throttle with very smooth acceleration and the added bonus of longer run times when compared to Brushed Speed Control equivalents! G2 Hydra50 features: Easy one-step set up Smooth controlable acceleration 5 to 10 cells NiCAD or NiMH 2-3 cells Lipo 6-12V Lead Acid Automatic sensing of number and type of cells Current limit cut-off 3A Hyper BEC 3 Internal Schottky diodes Auto cut-off computer Dimensions:-42mmx27mmx24mm Weight:-50g 100% Waterproof The G2 Hydra50 speed control is capable of an average discharge rate of 45A and a peak discharge rate of 60A making it a very capable & attractive option at such a low price! Ideal for your first steps into the world of Brushless marine modelling!
