This is the maiden voyage of my new HobbyKing Quanum Aquaholic Brushless Deep V Racing Boat. Its all stock configuration other then the addition of the onboard camera. The onboard camera freezes at times so I think I will try a different smaller micro SD card to see it that fixes the dropped frames problem.
All in all I am quite impressed with this boats performance for the money and its more fun then I thought as being a RC aviator I always have considered 2D terrestrial vehicles to be rather boring. I get about 5 mins of near full throttle racing out of one Turnigy 35-70C 3S 2200 mAh Lipo which is not too shabby.
There are only two small issues with this boat
The first one is with the bearing mount at the back of the boat which is made of plastic. The bearing which fits into the bearing mount is metal and it has worn the plastic away so the shaft now wobbles quite a bit. I have since machined and installed a brass sleeve / bearing holder which should fix the problem however I will not know for sure until the next time I go to the pond to test it out.
The second is with the water pickup tube. The stock one was too long and near the center of the prop. I made a new one from some brass tubing which ends at about the upper middle of the prop and it performed much better and kept the motor and ESC cooler then the stock. I could actually see water shooting out the exit port whereas on the stock setup setup I could not.
Ran 4 packs using the machined brass sleeve and it works great so problem solved :)
