    On the strut, I move the boat onto the stuffing tube and find a spot up the curve of the tube that lines out with the center of the prop shaft. Another way is to measure with calipers from the bottom of the boat to the center of the propshaft in the strut. I then cut a block of wood and sand in so it’s the indicated height of the calipers. Then set the boat onto the block, moving the boat back off the edge of the countertop until the strut is hanging clear.

    Note: the recommended depth applies to 1/10 scale models, like the UL-19.

    The rudder should be square with the back of the sponsons as a starting point. The depth of a rudder is a cut until it doesn’t turn good anymore, then buy a new rudder. Another way is the make it about 1-1/4 to 1-1/2” below the strut. That’s a pretty safe depth. Some angle the bottom of the rudder towards the transom, which has the effect of putting the bow down, on a hydro. Angling it back tends to raise the nose. This all comes at the cost of adding oversteering characteristics with it forward and understeering with it back. Personally, I think moving the rudder other than square, is trying to fix another problem by putting in a correction with +/- traits somewhere else.

    Well, I've been running this boat for a couple of months, and I must say I am very impressed. Hull is very stable, looks great, and I love the new motor. My boating buddy also has been running one, the only mod we made is a new turn fin (curved, stiffer) which holds it better in the corners.

    4s, stock prop (sharpened), hitting 48mph

    If you wanted to know what happens when you remove a turn fin from a hydro...

    I like the added yellow vinyl on the boat Chief! It looks good! I turned the fin in on mine just a tad and it helped in the corners. With an abc prop from Chris on 5s I was able to run full throttle laps at 59-60mph. This boat turns very well.

    60 on 5s is pretty darn good. Which ABC prop are you running?

    I'll give that prop a go on 4s. I'm at 48mph on stock, trying to break 50 on 4s.

    What prop would you suggest for that same motor in my RSX 310 rigger LArry?

    Sorry I had to cut the call short tonight. I am unpacked and ready to crash now.

    I ran 1816 prop on my UL19 for heat racing. My boat liked it. This last summer with 80-90* water temps. My motor came back at 130-140*

    ABC - H5 -rigger prop with some lift. 45mm -1.5 pitch
    Grim Racer- AQUB9768 45mm - 1.5 pitch -with lift
    The two above are basically the same Prop, The Grim has a little thicker hub, therefore a little stronger
    or a
    ABC - 1815-17-45(2) CLL with some extra cup, this would be less lift with a higher pitch. This may be a better choice with the shoes on the rear of the rigger
    or a
    ABC - 1816-17-45(2) CLL with some extra cup, (Check the heat with this one.)

    Chief, I saw your video and congrats on obtaining your goal of 50mph+ on 4s! 51mph not too shabby with that 1716. Good Job!

    Default Stock UL-19 hits 73mph with abc 1716 by dasboata

    I wanted to share another video of my latest run of my UL-19. This run I only got 73mph from the data logger and 72mph from the gps unit. The boat is all stock except for another spectacular ABC 1716 prop from Chris! Thanks again for all your great work! Also a shout out goes to Travis (kfxguy) for the Awesome dependable flex cable.

    Looks good, The motor that comes with boat will need to be replaced with a legal motor to conform with namba p limited hydro or they might include the new motor?

    Did you use the stock motor that comes with boat? I was told for namba p limited hydro I have to use the motors listed in the rule book. What batteries did you use?

    Thanks. Jerry

    Thanks Jerry! My boat was all stock except for the prop in that run. I'm not sure on the legalities of the stock motor for spec racing this season. ¯\_(ツ)_/¯

    Default UL-19 hits 59.3mph on 5s with abc 1716 by dasboata

    Here is my UL-19 running 5s stock at 59.3mph with a 1716 by dasboata. I just wanted to try 5s and didn't do too bad for the windy conditions. It may have another mph or two in it with calmer water.
