Udirc 2.4GHz High Speed Remote Control Electric Boat (Black)

Amazing Boat! I’ve been an R/C enthusiast for the better part of 40 yrs and have to say this is the best, most fun R/C boat I have ran across. The boat is very fast, extremely durable and responsive. Great control range as well, I’m running the boats on a 3.5 acre lake and have full control across the entire lake. The boat is approx. 12 inches in length, water cooling intake port on bottom, power on/off sensor on the bottom, flip sensor on the top, USB charged battery. I purchased two of these boats for some afternoon fun with friends, I was not disappointed, these boats are a blast! If you’re into the bump & grind, side by side racing, these quick little boats can be very exciting. We’ve done about everything you could do to a R/C boat… Side swiping each other rolling boats over the top of one another, (I can assure you the self-righting feature works great!) accidentally catching a rogue waves near shore launching the boat into surrounding bushes, running them into kayaks & docks, and often crashing them into one another or other R/C boats. Regardless of what we have put these boats through they continue to work flawlessly with no damage. I ordered two boats the first go around, I’m back to order an additional two boats and spare batteries. Extend the fun, BUY SPARE batteries! The charge last approx. 20 minutes. When the low battery alarm begins to sound I have been getting an additional 3-5 minutes of use until it begins to slow then it has to be brought to shore. My only caution would be watch the motor/battery temperature. The motor has a liquid cooling system that picks up water on the bottom rear and exits it out to the side. Keep an eye on the water inlet port so that is stays clear of debris so water can flow through the system. Great boats, I’ve bought 4 of them now w/ 4 spare batteries.

This is probably the 8th and most expensive speedboat my 11-year-old son has owned. To date, it's also the best. Perhaps his long learning curve on the non-rechargeable battery-operated boats - which are bigger and slower with less functionality and require a two-handed grip (in which the thumbs manipulate the joystick controls- see pictures) to operate the transmitter - helped prepare him for the handling of this speed boat.Fair warning: this boat is fast.I don't recommend this speed boat for beginners, young children who won't have the strength or hand size required to grip the adult-sized control, and users who don't have access to a large enough body of calm, unpopulated, and vegetation-free water (ponds that prohibit swimming are best) to enjoy its remarkable speed and maneuverability.As previous reviews have noted, the lithium charge is between 5-10 minutes depending on how much throttle you apply (rather than using the rudder and trim features) to steer the boat. The first time he took it out, the charge barely lasted 5 minutes because of his excessive throttling to turn the boat. By the third time, though, he had mastered the controls and enjoyed a longer operating time. He was able to really run the boat at full speed while turning, doing figure 8's, and side-to-side driving.As with any piece of high-quality but delicate equipment, read and follow the directions! Udirc includes a boat stand which protects the rudders when not in use. This boat requires extra care and handling, but if treated and handled properly, you will be a speed demon on the water.

This is actually a really nice and fast boat, but it has a few well known issues that can easily be fixed.... Do these things as soon as you confirm your boat is working. A big issue with this boat is water getting in, and it's happening in a few spots that need attention. The gasket on the top cover is too thin, so you have to either add another on top so it doubles the thickness, use removable waterproof tape on the top cover, or remove the gasket and fill the gap in the top cover with gasket sealant... So it creates a new gasket. Next you will need some clear silicone, add some inside the boat around the rubber cone that the rudder shaft comes through, you should put some marine grease inside the cone to water seal it completely. Also, add some silicone inside the boat around the water exit tube, and any gaps around the wires on the battery. You must keep the battery dry, use silicone on it! Although the water cooling somewhat works, the motor gets too hot. Open a gap on the top of the cooling coil, slightly bend the first coil up a little and it will expose an air intake hole for the motor. The motor will run cooler and last longer. Apply some waterproof tape over all the connectors inside the boat. Adding a bit of foam in the nose of the boat will prevent it from sinking, but instead float like a cork. Finally, if you readjust the position of the arm on the servo motor and put the rod to the rudder in a different hole, you can fix the veering to the left problem and also allow the rudder to turn more in each direction. It will steer left and right better. Do these things and what you drive on the water will seem like a completely different boat.
