Heres how I did mine. I think you can also just tack one onto each existing cap. Just be sure to match the polarities. The new ones come w/ 5 caps. The 4th and 5th are split between connection points of 1 to 2 and 2 to 3.

Here's a couple shots of mine. The final step was to heat shrink the capacitors together, I can't find the final pic though, sorry ...

Where did you get the card with loads of holes in?? What is it made of?

It's just a small plastic circuit board that I get from Sayal hobbies http://www.sayalkits.com/CatalogContacts.asp. I'm sure you can get them from Radio Shack or The Source as well. Just about any electronics place sells them.

Of course it is :doh: Just bought 2 off ebay. I have a couple of escs to do. Thanks

you can also get the same caps as factory off ose here and just parallel them off the original solder points underneath then shrinkwrap etc..easy peasy

I did mine the same way as Tiqueman, except I used perforated board to provide the caps with a little more support.

thats how Im doing my next set.

Thats a good improvement as mine are easy to bump and push all over. Sometimes I knock intot hem and push the shrink wrap out of whack. eh, it was the first one I did. I saw the idea and liked how they were connected. It works well into you need to put it into a confined area (top to bottom) then the wires gave me some trouble from where I tapped into it. You lose a lot of flexibility. But, it works perfectly.

Actually Im setting my next one up like the new ones w/ 5.

Here's two applications using the Etti cap board :

On a P-Sport FE 30 :

62559


On an IB 34 ( wires attached on top of board to allow for hatch clearance - tricky to solder)


625606256162562


If you go this route, be sure to insulate the bottom of the board ( used G-10 & some electrical tape)

Hi guys so I have the extra caps. I see no negative or positive signs on them just one wire is long the other shorter. Do they have a + and - or do you just keep each small wire in line and each long wire. BTW I have never added caps to anything before.....

There is a - on the side of the cap with the gray stripe. Usually, the gray stripe is always negative.

yep, the gray stripe is negative.
if there isn't one, the shorter one is negative, just like LED's

Thanks guys all sorted, hows this look? 62709627106271162712
I just paralleled them off each other, bit fragile but should be fine. I have wrapped them in heat sink too.
