introducing new 1/8 120a car esc

[lutach]

I know the company that makes them and I asked them to make one with dual powerboards, but that was the last I've heard of them. They have a 90A 6S and a 35A 6S ESC with switching BEC.

Here is a picture of the 90A next to that 120A unit:

hey lutach,

somehow I am not surprised that you aleady know that esc... you're the pope of bl-ESC's! I am curious who the manufacturer is... do you have experience with those esc?

what do you think, adding two 1000uf low esr caps would be ok? I just don't trust those three 330uf caps. a guy here in germany just smoked his new esc, in his truggy on 6s and a medusa 3680... I want to avoid that w. some extra caps. I am running it on 5s in a loxi xcelorin 1700kv.

thanks for a hint,
florian

I contacted them also to see if they could make a higher voltage model for me, but no word yet from them. The manufacturer is in Taiwan and not China. I don't have any experiance with them, but they seem like a solid design. One member here was testing the 90A 3S esc, but I haven't asked him any more info. I told the manufacturer that a capacitor bank would be nicer as the ones on the ESC could break off due to high impact. I've seen small capacitors do ok, but I like higher and more capacitors just to be safe incase one fails. If the warranty is good for them, try it out. That will be the only real way to find out if it'll work out good.

I don't want to void the warranty, but I'll do it in a way that I can reverse it w/out a problem.

my plane esc's were very smooth and never exceeded 35 degrees c.,w some extra caps (at least doubled the capacity of uf).

for boat esc you can get massive cap banks, eg. by etti or yge. when its good for boats, it should be good for cars, too. especially, as we have higher peaks, and more partial load, different to boats. they have higher permanent amps. but not such high peaks, especially when breaking.

I like big capacitor banks. Most that have used them do report a cooler running ESC.

I've been running that 90A version for about a year now, with great success. Previously it was used with 4s2p A123 and a Great Planes Ammo 36-56-2600 in my Rustler geared 18/46. Now everything is the same, except 4s 3700mah 20C Lipo.

The ESC's software hasn't impressed me too much. But then again I have NO CLUE how to program it since it was given to me to test.

I knew you were going to come in here . I would like to kow if you have a 4 pole motor to test it out with?
