Got a problem need HELP!

[Tony]

My bj26 is doing fine. Its just my other cat that i need help with. Here is the problem. The boat seems to work fine when out of the water. Motor runs, esc responds, servo working. But, when i put the boat in the water it runs like the batt is about to die. Checked the batt, and it is fully charged. So what could be wrong?

[chirotray]

need more info. esc? motor? bat? Prop? drive line condition? did you check battery static or under a load?

[Tony]

Everything new.
Water-cooled 2618 KV Brushless In-Runner Motor
50Amp Water-cooled Brushless Electronic Speed Control , seperate BEC
Thunderpower 2200 11.1V
2 Blade Chopper Propeller , Octura X642
I did tighten the flex shaft, because i thought it was loose. But, the boat still runs so slow.

Do you have another battery to try?

[Tony]

Yes. I tried it with another fully charged batt. Same result.

[chirotray]

Ok, how about your radio program? End-points, atv, expo, etc.? Everything normal? What brand esc is it?

[chirotray]

What is the boat? And are you only running one 3s?

[Tony]

Its a 32" cat. No idea what brand esc. I am running one 3s batt

[chirotray]

Off the top of my head, if every thing is functioning ok.......you need MORE battery. One 3s is slim pickings, not to mention its only a 2200. My blackjack runs 4s at 5000 mah. Was this boat ever fast on one pack, or is it a new to you boat?

[Tony]

It is new to me, and it was fast on one pack. It was recommended by rchobby centre to use one 3s pack lipo.
This is where i got it from.

I like that hull alot! How much did you pay it for? And for the problem, We dont know ANYTHING about the esc., that makes life hard. I dont understand only using one 3s pack. Weird. Make sure youre arming it properly, and check your pack voltage under a load. A lot of bad cells read normal just sitting on a table, then under a load they crap out. Make sure all you adjustments on the tx are neutral, or 100% depending. From there i cant be much more help without knowing more about the esc.

[Tony]

I paid $390 include shipping from down under to USA. IF, i have to change out the esc. What would you recommend?

[chirotray]

A castle Hydra. Theres a few levels of them, depending on how extreme you wanna be. Put one of those in there and a pair big lipos, and hang on! Id try to contact them first though, they said theres no instructions because theyre here to help, so call em up!

[Tony]

Yea, they give 12 months warranty on the boat. So, hopefully they'll fix it. Anyways, thanks for trying to help me out.

[chirotray]

No problemo, good luck.
