550e capaciter rating help

[jasoncook]

Hi all just had a flight with a 550e that I have just acquired after the first flight it wont spool up traced the fault to a broken leg on one of the capacitors ,an easy fix if I could read the numbers on the capacitors but they have worn off so can any one make out the type/size thats marked on theres its a 70A black esc Thanks Jason

Jason:
There is uasally 2 or 3 caps on the end of the sped controller look at the others see if you can make out their values. they should be the same.

Beware. These capacitors are always low ESR high temprature types. they deliver the short spikes of current to the motor and cancel the inductance in the battery and leads. Dont be tempted to use it with the caps missing or the wrong type

Post a picture of the remaining ones and i will try and ID them for you

Thanks for the reply i managed to find the caps a very bright light did the trick but i can only find them in Hongkong
"Nippon ChemiCon NCC KME Series 35V 330UF Capacitor"
how does this compare with a uk capacitor that i could buy at maplins. I am struggling with a match Thanks Jason

PANASONIC|EEUFM1V331L|CAPACITOR, RADIAL, 330UF, 35V | Farnell United Kingdom

There is your UK equivelent i cant find nitchicon's in UK only US so that panasonic one is the best i can find for impedance and corect value

Sry forget maplins they wont have any decent caps

After having my first Align 70A ESC just stop working one day and the replacement going up in flames after around 12 flights, I'd consider replacing the ESC with something a little more reliable, a capacitor falling off doesn't bode well for quality control & design. I've had lots of Align ESC's over the years and the 70A is the only one I've had fail.

The caps from farnell well after opening an account they wont ship for less than £20.00 so they are coming from hong Kong !!!

The rest of the ESC is well made apart from the cap mounting method. Recommend me something better that ain't going to cost more than the Kit Thanks Jason
