Esc and motor temps good.Lipos HOT!!!

i just noticed in that picture it looks like he has the 1527 motor in there.
it must weigh a ton!
I have that motor here on the shelf.lol

Yes, it's markf's boat I believe. Has a 1527. Vids in the insane thread.

i need a lesson in chargers.
i have the imax quattro b6 and dont see the mah reading.

Did your charger not come with a manual?

[britscoot]

yeah,i'm reading now.
No mention of mah up to now.sigh

...and YES, extra wire will help temps to go up because of the resistance. In this case your wire and connectors would also get hot. Good practice is to keep wires short, no extra slack... What temps are you getting? Measure it…

i'm going to do some experimenting and see what will work.
I thought having all that extra wire would cause heat problems.
will having more mah give me more speed and allow me to use a bigger prop?

[britscoot]

the motor and esc temps are good around 118.
i am going to run 4s2p with 1 x 4s and 2 x 2s and see what i get.

Has anybody water cooled the lipos?
I have a couple of big cooling blocks and was thinking of running a separate water pick up to the lipos.

[johnf]

Don't water cool the lipos. If you are getting them so hot that they need liquid cooling, you are over stressing them.

[britscoot]

thanks for that.
Just wanted to put it out there.
I'm hoping things will cool down when i run 4s2p.
just wish i had more hull room.

just wanna know where you point your temp reader? coz i have same turnigy ESC too, pointing mine @ the capicitor the temp goes 140-150s motor thank God only <110F. But pointing it to where the turnigy sticker is? its only 90s, no more than a 100s.
One thing also, try adjusting your ESC timing dont go below 15 on your ESC timing.
Mine now is between 120-130s running 3-4mins using 4s 4400mah 30C pack M445 prop, after adjusting the Timing.
I'm also planning to reduce my prop to 642 i'll see how it goes, hopefully temp will be lower a little bit.
I'm not an expert but, thats base on my experience.

Don't point your IR gun at the ESC sticker, particularly if it is white or silver. You will not get an accurate reading due to the reflective nature of light colors - black is best. Too, the shrink wrap will be cooler than the power board of the ESC anyway. The caps are probably the best place to take a reading as they are usually the hottest part, and are indicative of ESC stress. 150*F is high but okay - I'd not want to go higher.

The best timing advance will depend on the motor constriction and the load placed on it (amps from prop size).

Most chargers will tell how much has been put in. It's not just how MUCH you're taking out, it's how FAST you're taking it out that heats it up.

[pacificstr75]

Fluid, Thanx for the info. i really appreciate it. i'm glad that i found this site

Everyone needs a watt meter. If you had one, you could put it inline when charging, and it would tell you how many mah you used. You could also do static testing of how much amps you are using, gives you a rough idea(on the high side).
