HiModel 4s-8s 200 amp esc

[Gary]

You guys think i should try another ? Might have just been a fluke or there just junk.

[Mel279]

Which one is more efficient, is it by additional cooling or adding a capacitor?

[DISAR]

Just put the 8s Hymodel in my formula hydro i just built. Worked great until 3rd set of batts and its now dead. Only goes to program mode and wont even do that. Dont know if i should try anotther one or just upgrade. I was useing a 7 xl with a 442 prop . It went a 49 best with no heat issues so i was happy.........untill it crapped out!!!! OHWELL

What voltage? I have bought 4, 2 are dead. One thing is for sure, the ETTI is more reliable. Best thing with the HM is to go over the settings again because I think what they say "factory setting" don't take it for granted.

Hi i was running the early version of this esc http://www.hobbycity.com/hobbycity/s...12S_BESC_(Ver4)
in my lizard xtreme with Kb458xl abc H5 prop i burned the MOSFets on the 3rd run probably drawing too many amps it was magic to program with the card im now have an Etti150 race and love that esc not so easy to program but if you take your time you can get it right

Here is the vid

Did u install watercooling?nice video, its pretty fast, what is the top speed?

[EPower]

Hi No watercooling i did 87.6 k on that run and best speed was 91k after balancing and doing some work on the H5 blew the esc the same day

[Mel279]

Watercooling is a must not an option...but anyway nice boat and handling, I wonder what did u hit at the end of the video

Hi i hit a branch that was in the water close to the edge ripped the rudder off the bracket killed a 6kg metal gear servo no damage at all to the hull
very lucky here is a picture of the boat with the new esc

Cheers

[Mel279]

Yeah...really really lucky it just ripped the rudder, u should use a rudder with break off option just to be safe, that is a wholesome caps u got on your esc, I think it awsome, I've seen a someone use it on a bandit cat with a top speed of 127km/h.

[EPower]

I have to say this is my second Etti esc the caps exploded while i was running the boat with the first Etti blew the taped lid right off the boat LOL and lost it this is the one that Dee at etti replaced for me and he suggested to add the caps

Nice run. I would use a 42-43 mm prop. to be a little safer and when you want speed the 45mm. Your system must be drawing 130-150 amps with the 45mm.

Would any of you know of a way to activate the HM for full throttle only without the use of a receiver? I'm working on a project where I only need to run full throttle for 5-6 sec. I would like just to have a switch connected to a timer to activate the ESC and then shut it down. Any ideas? Thanks in advance.

The esc is watercooled, the motor isn't ?

What is the "T" fitting and extra line on the loop tube?

Here is a pic of how I plan to cool my HM200, with four tubes of cooling water AND a 40mm 5V fan mounted to one side...

What is the "T" fitting and extra line on the loop tube?

I have a rudder with two water intakes. One goes to the motor (not installed in the pic yet) and the other one is splitted by the "T" to two tubes on the ESC and then the two lines exit through the side of the hull still separately. The third exit line is from the motor cooler... Clear?
