***NEW*** Pro Boat UL-19 30" Sport Hydro

[dtacmed]

Thanks for the information. Definitely different from Vees and Cats.

I finally got run mine.
I ran it 5-6 laps box stock.
I brought it in then temped the esc and motor. Both around 138-140 on 4s. My battery's were very warm. I didn't temp them. They Gen Ace 5000mah 50c 2s.

So if I'm racing P limited hydro will I need higher C rating packs?
Also I felt the turning was too wide even with the steering wheel cranked all the right in the corners. Do I need to adjust the turn fin to get it more responsive in the corners along with the maybe adjusting the rudder turning?

I finally had a chance to run the ul-19 on some older 30c 5300 packs and it ran great.i can't wait to try some real packs(65-135c),the boat was super stable and temps were good 😊 For out of the box this thing does everything well,my faith in proboat is back on plane
Nice job pb

just wanted to give a quick update as my previous posts probably looked like I was hating on proboat. when in fact that is not the case. in the last 4 months I have spent over 1200.00 dollars with proboat/horizon hobby. and possibly more with the veles out now. as far as my disappointment in the ul-19 when I first posted and the manual thing, my ul-19 has turned into the boat I wanted now. my new zelos 36 had the recommended prop down listed for 6s run. being as it was not runnable when I got it I figured I might as well steal the prop off it on put on my ul-19 and run on 6s.....and wow. this is what I wanted when I bought it. it absolutely flew down the lake. and best part was the run time and speed I was more than happy with. I'm sure I sounded like a giggling school boy as it made quick work of the space I was running. and.....ran all the way to low volt cut off. I wasn't going to take it with me to my reunion to red fish lake this weekend but now I must !! hopefully I can get my new zelos figured out b4 the weekend and it can come to I'm dying to get it wet. thanks again everyone!

ran all the way to low volt cut off.

Good to hear you're back running in the fun column again. Do yourself a favor and don't run your packs down past 3.8-3.75V which happens well before the LVC cutoff kicks in. Your batteries will thank you for it.

[Brushless55]

I agree, keep atleast 20% left in the packs.
Me personally I try having 25-35% left after a run.
Battery life is much better.

thanks for the advise! I usually try to stop b4 lvc but I was just to tickled about what it was doing I lost track of the time I had been out lol. seems like I read somewhere about being able to change that setting in the esc or am I mistaken? Ill do some digging around and see if I can find something. I think I can get more out of her still as I just threw the batteries in the middle of the trays and still had my strut picked up a bit. my turn fin is straight vertical and I can tell its dragging the right side down quite a bit at the speed its going. I started out by just seeing if it would run the whole time without shutting down and just got side tracked goofing off. I was just gonna sell it or give to my son but now I'm thinking I'm keeping it

IF it's running very wet (lots of weight on the nose) and not coming anywhere near getting loose, then move the batteries back to loosen up the front end (get more air under it).

I have my packs all the way to back and still running very wet.

Do I need to tilt the turn fin? What about the strut? I ran a 1816 prop with strut in stock position do I need to drop it down 3/16"?

I am new to boats, so someone else may need to correct me.
I set my ESC for ~3.2-3.4 volts. Then I put additional voltage testers on each battery. I set them to 'scream' at ~3.6 volts.

Here is the 'screamer' i use....others exist....

That way I hear when the battery is getting low but the ESC never stops the boat.

The 'Pros' need to suggest the correct threshold, but when it starts screaming constantly at 3.6. after they sit idle, they creep back to 3.75 and stay there.

in series ?

[TRUCKPULL]

in series ?

Yes - they are 2S packs, in series to give you 4S at the Motor.

I have a pair of them from Giant Power for sale seeing that I retired my Spec boat.
