Yes it is the updated hull...turn fin area has been strengthened to prevent cracking. Although the same old cheap esc will easily pop a cap if not careful. I added two extra caps to minimize this problem. Other than the caps failing this is a verycool boat...go UL-1's.

thanks guys i have been putting off buying the UL-1 cause of the hull defects , i have 2 new 120 hydras sitting around so i might use 1 in the UL1 .

If Steven has current stock.. they need no updating..

Just so you know.. the ESC has not changed.. Its a good idea to update the cap but truth is if you run reasonable props and or keep the boat out of the weeds it will likely be fine.

IF.. you see silicone around the water cooling jacket go ahead and call Hobby Services for the new end cap and o rings.. We have a few motors out here with this fix.. not that many but if you get one go ahead and make the call.. ask for Jack or Lisa.

Keep us posted!

Is there any way to tell by looking at the outside of the hull whether it is one of the newer versions? Is the fin bracket the same or has the footprint been enlarged?

FYI, I've burned up 2 ESCs w/ Aquacraft "Grimracer" recommended props and no weeds. That ESC is junk, let's be honest and up front for once. The UL-1 is the best or most fun of all RTRs, but it has alot of QUALITY weaknesses that could be avoided w/ a little QC and maybe an additional $10 in manufacturing funds.

just so you guys know i have been using that motor and esc in a different hull (mini mogli and spec delta 26") for about 6 months and have no issues. dont over prop and you wont hear the pop.... it makes a great esc with the SV and ammo motor as well... i own 3 and have burned zero

From what I have been able to understand, the ESC issues stem from overpropping or running near the limit (40x57/3 is near the limit) and the culprit is the capacitor. Adding a second cap seems to eliminate many of the issues.

I burned up 2 ESCs w/ a 40x52/3, closest metal prop to stock. The ESC is not dependable; howabout we quit BSing ourselves.

When you say burned up... what does that mean? Blown Cap or something else? Hmmm, thats not good, thats the prop I'll be using. I'll be adding an extra cap or two.

There is also more that can cause problems besides the prop that can cause higher amp loads. Such as the setup of the boat, friction in the drive system, timing of the motor.

Rough water will cause the amps to spike as the prop bounces in and out of water...prop turning loose then catching water over and over again. These amp spikes will pop a cap.

[JimClark]

My point is that to say in a general statement that an ESC crap without backing it up with how the boat was set up and looking at all the possible cause's does not help new people at all in solving their problems. There are lots of guy's running them hard here in the Seattle area and not having problems but they are set up properly for racing and running very free.

WOW guys i have started something here ! ,i was more worried about the hull cracking around the turn fin area to be honest . I think we would all be gulity of overpropping & pushing our boats a little hard to see how quick they can go & thats why one of the first things i do is upgrade the ESC !!! i cant tell you how many ESCs i have smoked in my SV27 s ,cause i went 1 mm bigger in a prop :-) & to be honest how much quality do we expect for 300 dollars ???? & dont get me wrong there seams to be an issue with the caps but it sounds like an easy fix , compared to the turn fin ripping away from the hull now thats an issue!!!!!
