I just orderd a duratrax digital piranha ac/dc peak charger to charge my battaries with. I think it will do good charger my batts for this boat. When i go brushless i will try 12 cells and see how it is on the brushless system. I am thinking of putting in the stock supervee 27 brushless system in this boat. Is that a good choice or do you guys think it isnt a good idea and go with something else? Also would a x440 prop be a good prop over the stock? How many blades 2 or 3 blades?
