Keep in mind what caps do- they prevent spurious downspikes in voltage from underwhelmining the input voltage to the speedy which will cause damage. The best way to handle this is to : #1 - use robustly rated batteries ; #2 - don't run the batteries down too far ( a 4S pack off the charger is 16+ volts - a 2V-4V downspike isn't as dangerous to the speedy as the same downspike when the pack sags to 12-13-V during sport running) #3 - keep your setup out of the danger zone.
My sarcasm (which I hope was taken with good humor - but really come from costly experience) was meant to cause some caution in pulling the trigger on a potentially destructive situation. I frequently see folks rigging what they call a "SAW" setup but what usually is going on is an attempt to overpower the equipment in an attempt to get a few high speed passes the easy way and qualify for membership in the ZSP-WTS? Club *
I've been to a few SAWs, hold a few records, but in over roughly 20 SAWs I've NEVER seen any "SAW" setup in the realm of what the OP is talking about attempting. Adding caps to such a setup isn't the way to get more speed and keep the smoke in.
Pictured is an Ettie cap board on my P-Mono - had to find room to squeeze it in so a little modding was in order. Conversely, my racing teammate uses a Neu 1527 2300KV motor in a similar boat with NO added caps on the original T-180 but the high quality race packs we use prevent (for the most part) destructive downspikes.
oh I see..... a pic of my puny T180 caps wasn't good enough Huh? you just had to post pics of what looks like the space shuttle's computer mother board glued to the top of your ESC.
Thanks.... now I have a puny cap complex,

Hey, that ain't nothin' - (in my best Crocodile Dundee "Now That's a Knife" voice) :
This is A CAP BOARD (siting on standard size servos for size comparison)
Todd, BTW the closer your outboard cap board is to the speedy, the better it does its job. You might consider relocating it closer & shortening the wires.

ahhh thats why i took a close up. so nobody would see how wrong i've got it set up. and thanks for the info. the only part i didn't like was the shortening the wires advice.... as I hate soldering
and with my skills will probably catch esc on fire with soldering gun. but I'll move it and re-solder wires to esc. ( i hope thats what you meant by shortening)what size motor do you have that takes all those caps? did you get your engine from a chevy volt?
Thanx guys and to tony, I read your quote And laughed I'm a good sport and can appreciate truth in jest :)
My reason for the caps thread was based on saw runs but also getting more outta my esc's, which I made a mistake in writing that they where continuous 320 rather than 180 with burst of double h2o 1 my disslekcia took over :) I recently realized that I'll probably have more fun running 4 and maybe 5 cell Packs rather than 6 with these kv motors. I just swapped out the scorpions with Leo's 4082 2200kv and wanna push a bigger prop on 4s so that's the other reason for caps. I was running 447s at 63 mph with scorpions and temps where under 105 after 5 minutes. So I wanna try the same with new motors leos 2200 4082 and maybe Bigger wheels for the continuous quest of speed.
Thanks Jim. That comment qualifies you for a free autographed copy of my latest inspirational book : " How I Made A Hundred Dollars in Real Estate "
I'll pick up that Pulitzer Prize winning book when I give you your "TOP SECRET TWC" long sleeved T shirt at the Nats. JIM

Caps aren't added for getting MORE out of an esc; they're designed to PREVENT getting LESS as when the esc fails from too much ripple current from underforming batteries caving, too long wires, and/or severe downspikes from overly ambitious motor loads. { I always preferred Ripple Strawberry over Ripple Current BTW }
You wannagofaster ? Here's what you have to look forward to - hope you have a strong boat : - enjoy
I hope to avoid both of those clubs ( ZSP/WTF & ZSP/LFB )
it seems to me that saw boaters are just model rocket enthusiasts that are afraid of heights (and/or rockets).
what does SAW stand for?
or are you enjoying 3 rc activities with your saw at once.
1st. it's a boat, then it's a plane, then it's a submarine! Wow you guys get 3 rc vehicles from one !

I think you've discovered the secret of the SAW racer. Besides being model rocket enthusiasts that are afraid of heights (and/or rockets) [that's funny !], SAW racing is for those genetically impaired from avoiding oval racing turn buoys
Technically speaking, SAW stands for "Straight A Way ", as in " Honey, I'll go see the psychiatrist Straight-A-Way after the race.

if school would have been this funny and educational at the same time, I'd be a rocket scientist by now, but unfortunately I focused on the funny and not the learning.
if nascar gets made fun of for only doing left turns, what's said about saw racers who can only go straight?
Thanks properchopper your wisdom and humor is making my learning alot of fun......... even though you have given me a puny caps oedipus complex

Glad to keep the grins in the learning process. Done a lot of teaching in my day - basic philosophy : "People don't care what you know 'till they know that you care".
FE boating is a great hobby/sport and sharing and caring is what it's all about. If "Da Truth" is sometimes hard to swallow know that it's often served up from a good place.
Going perfectly straight between the lights (330 feet) isn't always that easy. According to a questionably famous mathematition/shoe salesman, Sir Nigel Hypotenuse, diagonal paths take longer and should be avoided.
