Aquacraft UL-1 ESC fix quastion...

One CAP or Two? Would like input from GRIM...

Love the UL-1 but was only able to run it twice and my CAP leaked. I ordered a couple of replacements from Kintec like the ones recommended. Is it more benficial to install one or two replacement CAPS? I don't race but I enjoy running my boat about 3/4 throttle for fun. Once in a while I do throttle her up on the straights for a few seconds. I use my recreationally and woud like to run it for 8 - 10 minutes at a time. Any suggestions would be greatly appreciated!! Grim your design of theboat has been great! I hope Aquacraft improves the build quality and strengthens the turn fin area!

For 8-10 minutes of run time, you will need some 10,000 mAh LiPos as a minimum. We run 5000mAh packs and run 4 minutes max in order to have a safety margin.

Since the original cap on esc has failed, I would install two of the caps sold by Kintec. The more caps you use the cooler they will operate.

I'm amazed of how this will fix a bad esc.. very cool

It is interesting why this was not done by people designing ESC's. So simple and only $1.00 more when purchase from electronic store ( unless the purchase was made from DOBY ), never mind the real coast of the extra cap. This makes me wonder.... Is there a disadvantage of installing extra caps???

no disadvantages only advantages

Thanks for the CAPS more on Run Time

Just a note: I am running 2 Trak Power 4900 MaH 25c packs and I ran around 10 minutes or a little longer. When I charged the packs they still had more than half of their charge available. You are right when stating you need about 10,000 MaH. My packs were cool and I did not find any significant temps from the electronics except the original CAP bulged and had leaked. I found this out when attempting to run a second time and the boat would only go about 20 - 30 feet then cut-out. I would re-arm the ESC but it would do the same over and over again. I am waiting for my CAPS and will try again. Other than that the boat was spectacular out of the box. Would like to see an improvement on the finish from blemishes. EXCELLENT DESIGN!!

CAP Replacement

Thanks for the help. I am going to followup on my order for Kintec, I hope they arrive this week, I ordered them last week.

I didn't know you could leave it but I clipped mine off as close to the case as possible and then covered the ends with liquid elec tape.

[nel9862]

Did you have any issues with your fix pescador?

[pescador]

Not at all, she's running great I put the 2 new caps on the wires as close to the case as I could and covered the leads with liquid tape.
And the new bullets for the motor.
I pretty much keep at WOT when running and try to remember to time it so I come in before the lipo shield kicks in.

Hi, im new to the ul-1 also and i was wondering what about running a hydra esc (120 or 240)? Is there an esc motor combo out there that you can just run with no problems. Is the motor that comes with the UL-1 a really good motor or does it have its downfalls?
