You asked for it and now it's here-the ready-to-run Pro Boat® UL-19 30-inch Brushless Hydroplane. Its design is ultra sleek, with no turbine housing or rear spoiler. And boy is it fast-you can cruise up to speeds of 50+ mph on 6S power thanks to the 6 pole water-cooled motor and 120A ESC. A waterproof Spektrum 3KG servo lets you take corners at full speed without fear! On top of that, the UL-19, which is built to NAMBA race specifications, comes equipped with all the aluminum running gear you need and a stainless steel turn fin. This is adrenaline-pumping, heart-pounding action you won't soon forget.


In-Depth Features:

  • Lightweight, durable fiberglass hull with matching canopy and removable vertical fins: Because the hull is lightweight and durable, you can push this hydroplane to max speeds in race condition waters. The canopy, like the hull, is constructed of hand-laid fiberglass. The vertical fins are removable and replaceable. In case of a bad crash, they will simply break away without damaging the hull.
  • Extreme power from waterproof electronics: The UL-19 uses a Dynamite water-cooled 120A, 2-6S ESC that can handle more amperage than needed to run the boat with authority and speed. The new 2000Kv 6-Pole motor features a large rotor that greatly increases motor torque.
  • Stainless steel two-blade propeller: An aggressive boat like the UL-19 deserves an equally aggressive two-blade propeller. The UL-19's propeller lets you take full advantage of the hull's performance. It features a high-pitch, high rake stainless steel propeller that produces a tight thrust cone that results in better propulsion and higher speeds that won't overload the electronics. You'll be able to reach speeds on 4S that could only be reached on 6S by other boats.
  • Interference-free connection: The included Spektrum DX2E DSMR® 2.4GHz transmitter will provide a clear, precise connection while the hydroplane is on the water.
  • Aluminum adjustable propeller strut: Use the aluminum adjustable propeller strut to tune the boat to various water conditions, from glass smooth to windy and choppy. The square-bottom propeller strut allows more precise adjustments by acting similar to a trim tab usually found on Deep-V boats.
  • Aluminum break-away rudder: The aluminum rudder features a break-away design that will safeguard the transom if the hydroplane hits an immovable object on the water or runs ashore.
  • Stainless steel turn fin: The stainless steel turn fin will keep the boat glued to the water whether you're going straight or full throttle through a turn.

Boat is hard to plane, it dive instead. Adjusted the prop but still hard to plane. I need advice if someone knows what to do. I even positioned the battery way back. Any suggestion? I’ll update my review if there’s a solution.

Pro Boat UL-19 30" RTR Brushless Hydroplane Boat w/2.4GHz Radio
Crazy review about this awesome boat, plus in around 10 years of off and on ordering, buying litterally hundreds of items from AMain, from $1.50 parts and many high end RC kits plus everything in between, anytime I've had a question or problem or needed to return something, AMain has been 47,924,745 times better, easier and faster to work with than any other online retailer Ive ever dealt with. Ive recieved answers to questions after hours on Sundays, and I cant ever remember waiting much more than 24 hours for a reply to any email. The only time they couldnt help me with a horrible product was because I had to deal with the company directly, and I assume its because AMain would go out of business if they had to replace every subpar product that the other company makes. And in comparison, while I eventually had my item replaced by the other company, it took weeks to happen, because unlike AMain, They would regularly be seceral days or a couple weeks to get replies from them. Also, all I wanted was either some replacement screws that were longer than what came with the wheels, or I just wanted to send them back, get my $150.00 I had paid, and buy a set of Vanquish wheels so I would have a setnof cool rims that wouldnt fall apart within seconds if I actually ran my truck with them installed. But because I had bought them from AMain, my only option was a replacement set, which of course had the same exact tiny, cheap-o made in china screws that were way too short and were basically stripped out before they were even put together because the holes were machined too big for microscopic screws that were only long enough to get 2 threads started before they bottomed out. There was also the $50.00 bumper of theirs that sheared off the mounts the very first time I "bumped" into a rock, and tge first type of rock sliders I got looked like they were welded, painted and machined by Ray Charles after 13 shots of 151 and way too much ambien. Thats when I completely understood why AMain states that they do not and will not deal with any product issues from that one RC four wheel drive company... But 99% of people I know will say that AMain is awesome when it comes to all things customer service... Unless you just happen to be one of those people that will always complain because its literally impossible to please you..
