When it comes to brushless R/C boat action, it simply doesn’t get any better than this!

The Quanum Relentless is the ultimate Catamaran Racing Boat offering high speed, excellent handling and killer good looks. The vibrant red paint scheme and expertly applied racing decals are sure to turn heads wherever you go!

A potent watercooled brushless power system comes pre-installed providing extreme power to the prop. The motor is an outrunner which produces massive amounts of torque. This allows the boat to get on step almost instantly upon hitting the throttle. The precision machined alloy rudder and pre-installed high torque steering servo makes for crisp steering response and keeps the boat upright during hard cornering.

The hull is constructed from lightweight yet durable ABS – this is where the Relentless differs from the others. The hull has a beautifully painted gloss finish just like fiberglass, yet it’s offered at a much lower cost. The decals are applied before the final clear coat, sealing them from the elements and providing a top quality look.

This boat will be ready to run in about 10 minutes after opening the box thanks to the high level of pre-assembly. You will simply need to bolt on the rudder and propeller, connect the steering linkage, install your receiver and you’re ready to go!

This is hands down the most fun, exciting and easy to setup brushless race boat we’ve ever had our hands on here at the HobbyKing office, we know you’ll love it too!
