Hi,:tiphat:
I have a 36"shock wave that is fe now,
My esc cap temps are 160f and up some times is that to hot for them ?:unsure:
Boat setup is,
36"Mono, All stock hardware except for collet and prop, Motor is a Feigao 9xl 1898kv,

:thumbup1:
Now I put a 4074 2200kv motor in it now and more caps,
Runs a lot cooler and better now,
Also using a x646/3 prop now.

Esc is a Turnigy marine 120a and programed setting are 2 4 3 3 with card,
Cell are Turnigy 4s2p 40c to 50c 3000mah and 5.5 bullets all the way.
Ran today with a p230 for 4 minute runs and gps at 42.5mph,
All temp cool 98f, Just caps where ,160f, 198f.

Thanks for any info.:beerchug:

Caps are fine there in my opinion.

I was testing props today and was not sure about the caps,
Did not want push them to far.
First time I ran the boat it ran good but had a wobble side to side at top speed with a x442 at 36mph.
I thought the cells needed to be moved lower to center of hull to stop the wobble.
But I had to go forward to because of the rails in the way,
The boat ran ok maybe a little wet today.
I want to test some more and prop up some,
Will also move cell back to the sides of the hull and see what happens.

Temps were, caps 227 F, esc 98 f, motor 115 f , cells 80 f.
Cells were Turnigy 4s2p 25c to 35c 5800mah.

Cap limit is normally 105* Celsius.......................you were real close. I'd prop down to an x442.

OK thanks, That good to know.
It was faster with a p230 at 42.3mph and caps were 170f,
I think the p230 is the winner, Have to test with one some more.
The cells were 110f , esc 90f, Motor 98f.

I'd add some. I added two and they don't get over 120

Ok that may be a good thing to do.
I have some caps that came in a box with other stuff I bought.
What kind of caps do I need ?
How do I do it ?
Have any pictures on how you did it ?

Thanks for any info.

Do you have trim tabs, if so might need adjusting

Hi,:tiphat:

Looking to try my setup on 5s using the 4074 2200kv motor and x646/3 prop.

Do you guys think it will be ok ?

Thanks for any info.:beerchug:

I have the SeaKing 120a ESC and the cap temps were in the high 100's like yours. I removed the stock caps and installed 2 caps that I got from Off Shore Electric. Cap temps are now around 120f with no changes to the power system.
