hydra 240 temp range?

[tiletony]

guys, i have been running the etti 150 (which i love) but it went down with my blackjack a while back. bth i still haven't recovered....any way i have been running my new MM 30" cat(thanks nick)with a nemesis 9xl on 4s with a x642,x640,and x645 props...and the hydra gets about 2 min run time with each set up before it reachs 200+....i stop for a min or two when it hits 170 let it cool a min then run it ...is 200 to 205 ok for the hydra??? should i kepp on going???i have a seperate water pickup cooling it so i belive it gets great water flow...my old etti stayed below 150 all the time it didnt matter what prop i ran???

Is your timing correct for the motor?

[tiletony]

i belive so i will double check but i always set the timing on the esc at the lowest setting cause the last time i had it set high i caught my blackjack stocker motor on fire

[j.m.]

The blackjack motor is a 6 pole I believe...

The feigao you have is a 2 pole motor which requires a bit higher timing.

I'd double check with someone more experienced on that before running though.

that i didnt know ....i will check it out..i thought the lowest timing would give the set up a lower temp, but i will chevk it out thanks..

[j.m.]

If I remember correctly (Im just passing info read on the forum here, don't take it as experience) the lower pole motors need more timing to run efficiently.

[tiletony]

on the castle instructions it dosent say any specifics..it says the lowest setting is "max efficience and run time"normal "balance power and runtime" i have it set at lowest but i will try it at normal...if that motor runs efficient it shouldnt make the esc work so hard?

[Jeepers]

sounds to me your boat might be running a bit wet as well.

[ozzie-crawl]

a 2 pole motor should be run on low timing generally, higher pole motors require more timing.
sounds like there is somthing else going on to me.
i run a 8xl in my MM, with a s215 pranther (around the same as a x640) i get around 3 minutes run time,my esc (mystery 200a) is usally around 120f

Yeah that is way too hot. What Firmware does the 240 have in it?

Thats what I was thinking too Ray. I remember your issues awhile back.

I will check out the firmware. Which number should it be? If I remember correctly when I plug it in the cc software automatically updates it. But I will see which it is. Also I did have the mystery 200 esc in there and it took hit 203 degrees and it didn't smoke or anything it just stopped working. Could it be my battery conoctions? I am running thunder power 8000mah 2p 4s. So in series with deans connectors. I read on here the deans are only good to 60amp and I am pulling 140 to 150( only peakamps) could that make the esc heat up?

[Raydee]

So you are running 4s right....not two 4s packs in series

I would def get rid of the deans connectors for something that can handle more amps but I don't think that would be the only factor in both your ESC's running so hot.

[tiletony]

Ya 4s total. Not 8s! Although that would be cool.... What tŸpe of connectors should I use I will nees to make a Y connector to run there 2 packs in series. If the connectors aren't the issue I am at a loss. I have had nothing but issues with the hydras. I think I want to go back to the etti.

[properchopper]

Make something like these. With lower resistance in your connectors, the SC doesn't have to work as hard. I agree with Raydee that you'll also have to check the firmware & make sure that your timing is correct. Definately use at least 5.5's between the SC & motor. I sometimes run my Titan 29 on 4S2P with a 9XL, CC Barracuda 80 and a X442 and the SC never gets over 120-135. Your MM should run even freer with similar or lower temps.
