Castle 1800kv in geico

[dano1]

Installed a castle 1800kv motor and turnigy 125 amp esc, im running a x642 and id like to know where this set up would be best to run on timming wise and battery maxx, i took it for a test run on 4s then 5s then 6s and got some high temps on esc, couldnt open her up due to choppy water, im getting 125 degrees at the esc and water is feezing cold, motor and battery are cold, dont wanna burn anything up. any advice would be appricated

You runnin' the 1512 or 1518?

[Rumdog]

5s max. 15 degrees timing. 125 isnt too bad on the esc. Was this on the caps or?..

[dano1]

Ice cold water and was on esc itself, caps were tad cooler and motor is 1500 series

[dano1]

1512 motor

temp was probably from spikes while running 6s. 5s should be your max if you want good temps.

[dano1]

i tried 4s and 5s....still was getting warm in ice cold water....and didnt get to make a good pass....didnt push it, and i know thats not great on esc just half throttling

[dano1]

whole idea behind this is to get some power out of it, im not totally sure where the timming is on the esc, im going to check it, the esc when i got it was a paralel set up....dunno if that means anything and im in series now

Ran the same motor in mine on 6s with no trouble. You might be a little aggressive on your prop selection. I was running a m440.

that's a good point
almost 40,000rpms :buttrock:

I'd recommend 7.5 timing on that motor, i had best speed readings on mine at that, my temps were real cool though, If your wanting to run 6s i would highly recommend throwing a T180 in her, your temps would be way lower too.

try a x 442 might not be letting the motor wind out, just as an example on different boat i was using a x645 motor was very warm switched to a x447 gained 5 mph and temps were cooler

[dano1]

i like the seaking 180, been good so far, im gonna make sure that esc is set correct then run again and hopefully get some serious passes in and check the temps

I thought it was a 125 amp???

[dano1]

getting ready to place a order for a different prop, and do some tunning

[Rumdog]

What are your goals for this boat?

Yeah thats a huge difference in prop. Im going to be running similar RPM in my riversport cat and was planning on a m440...what were you running for esc with this setup blackcat?

To the OP: That is a lot of prop to push at that RPM, especially with a 125A esc. I bet that setup pulls a lot more current than you think. Once you get over 35,000RPM its hard to keep current spikes down.

[dano1]

yes, im running a 125 amp esc and checked my order and lucky me .......i ordered a x442, that should help this problem, my goals?.......im wanting to hit some high 50s with the boat and have some cooler temps, its just a play time hobby so im not racing, im just curious what i can push thru it and get the max out of it without damage. I want at least 5 minutes run times

[LarrysDrifter]

Higher amp rated esc.

[6sHyper]

1512 1800kv+ T180 esc+ x442 prop will most definatley get you high 50's and run nice and cool on 6s IMO and from my experience with that exact setup in my apparition. I highly doubt the 125 will hold up though.
