[MADRCER]

Boat runs great!! Where did u get the turn fin? Did u have to make a new bracket for it? What lipo's/brand are u using?

Take care. Jerry

Thanks Jerry. I replied to your PM. Good luck with it.

I been meaning to tell you, if you aren’t planning on racing or doing oval time laps. You really don’t need a curve turn fin. Stock is fine for straight lining. I do heat racing and needed the curve turn fin.

This UL 19 is my first ever Hydro, forgive me if I sound a bit uneducated here. It’s because I am lol. This boat is designed only for RTO? (Right Turn Only) Correct? I really don’t want to damage anything when it’s only been in the water for 7 minutes lol. Thanks in advance guys.

Correct - Right Turn Only - at speed.
You can turn Left at slower speeds.

Finally got some video of my "Race Prepped" UL-19 in action. Updates are pretty basic... Mojo Racing Sport 21 sized Turn-Fin, OSE Carbon Interior motor tray, OSE Flex Cable and Octura Coupler. Spektrum digital Hi-Torque Servo. Basic tuning.

THIS is how the UL-19 is intended to be used... :)

What does a flashing red LED on the speed control mean? Cant find it in any manual. Thanks!

Thanks!

Darin, long time no see! Found a club in Spokane to race with. We have pretty much a class of all UL-19s. Would you mind telling us what prop you are running in the video above and if you are running 4S, 5S or 6S?

Thanks,
Kevin

Trying to help a friend.
His new completely stock UL19 is running into what appears to be LVC limp mode 30-45 seconds into his run.
He is running 2, 2s 60c batteries, 4s. Nothing is hot and it rockets away at first then slows to a crawl which makes it hard to get back due to the submarine-ing when traveling so slow. He's tried other batteries.
With good batteries, good connectors, and esc parameters verified what is your first thought that comes to mind?
Is there any known out of the box issues with stock UL's resembling this he should be aware of?
He is about to replace the esc and motor.
I think there might be a better less extreme solution than that.
What conditions cause this?
Any help, guesses appreciated.

Have him contact Horizon tech support. They should be able to assist with sending him replacement parts if deemed necessary. I just read about a similar situation with another new UL-19. They first replaced the ESC, but the issue continued. They then swapped the motor, and the issue was resolved.

The two of you can do some initial troubleshooting looking for conditions that might cause the ESC to shut down. Because you've said that you've eliminated settings and batteries, I would look at driveline alignment. Is the flex cable rubbing on the stuffing tube as it exits before the motor collet? Is there a 3mm gap between the drive dog and strut? Does the flex cable slip into the collet easily, indicating proper motor alignment?

Seems that's the right route.
