Last year, I presented an introduction to RC boats that focused on smaller models. This time around, I'll be stepping up in size and power. The boats featured in the previous article (Aquacraft Reef Racer 2 and Minimono) measure about 17" long. The 26" Pro Boat Shockwave 26 ($230) I'm reviewing today is significantly larger. The greater size allows for additional capabilities and performance tuning while also introducing more maintenance overhead.
The Shockwave 26 is only available as a Ready-To-Run (RTR) package that includes the fully-assembled boat and a pistol-grip transmitter. You have to provide a 2-cell or 3-cell LiPo battery and a charger. I think that I fall right into the target demographic for this boat: sport boaters who are ready to step up in size and power from beginner models.
The hull of the Shockwave is made of molded ABS plastic. All of the running gear and radio equipment is located on an internal tray. There is a sealed hatch cover that keeps water from seeping in (mostly). Thumb screws are used to secure the hatch in place. On my model, the e-clips that make the thumb screws captive were prone to fall off. So I tacked them to the screws (carefully) with CA glue.
Power for the Shockwave comes from a 2000kV (rpm/volt) brushless motor. The motor is regulated by a surprisingly small 30 amp ESC. Both of these components are water-cooled, using a pickup system located in the rudder. Sitting astride the ESC is a 2-channel 2.4GHz radio receiver. Further aft is a Spektrum S603 steering servo that actuates the rudder. The receiver and servo are waterproof units.
