When building a twin drive catamaran, and u want to run, say 12s lipo, is it better to run 12s on each side/esc or can u run 6s on each side/esc for a total of 12s? Or is it just a personal preference?

12s on each side if your going to call it 12s... -
How would it do performance wise...."They call me Fast5sRevo88 over at RCM"(in cowboy voice) "There's no such thing as to much power!"Comment

Depends on hull, motor, prop... But usually 12s cats are insane.Comment

Well, it could be too much power, but i want to put it in the Toysport Jolly cat twin, but 10s might be better?"They call me Fast5sRevo88 over at RCM"(in cowboy voice) "There's no such thing as to much power!"Comment

I'd go with 6s max... It's not that big of a hull.
For an economical, but very powerful setup, do twin 580 6L's on 4s. Two packs, one for each side.Comment

I don't know about the Jolly being a wheelie monster ... I'm running a twin jolly on 8xl's and 4s to each motor and I love it!
My only problem when I first built it was - it porpoised alot! Contacted the manufacture(Joseph Toth) and he sent me an additional part to add to the back of the tunnel and now it just gets up & goes!We did it with a Bang!

So, this is a 4-6s cat...."They call me Fast5sRevo88 over at RCM"(in cowboy voice) "There's no such thing as to much power!"Comment

I will most likely be running 2 Medusa 70-80mm motors in the 1600kv range on 5 or 6s, don't really know much about boats, so what size prop would be a good starting point?"They call me Fast5sRevo88 over at RCM"(in cowboy voice) "There's no such thing as to much power!"Comment

ok I do admit that I believe in the "too much power is not quite enough" theory
But I wouldn't go as far as to put 10s into a Jolly cat even though that is very
it might not be a good introduction into FE
Eodman - yeah the tunnel tab fixed the porpoise on Graham D's one he made a bling stainless adjustable one. Might have been half the issue. It is a good handling hull for a small boat, but I personally if i was to build one for myself I probably go for 2 9L on 4s each and start with an x632 on each side counter rotating.
Choosing an Esc is a hard choice at the moment... you get what you pay for, and sometimes you don't although I have been lucky with some chinese ones so far, touchwood, my 120amp hextronic from hobby city got a watercooling and conformal coating and has been good to me for a few years, i think its got thermal protection as when I had it in my rigger trying silly props in nimh days it would just shut down if you over prop the hell out of it (x455 on 8xl 
) IMO If you want to spend the cash once and do it right then id prolly go shultze. I-care has a big sale on at the mo. Have you had any other boats BassBoat88?

The only boat i've had experience with is a SV27, but i'm used to the power of brushless because of my 1/8 buggy and truggy i run on 6s and have had in excess of 65mph. I am fairly new to boats and i'm not scared to spend money
. And instead of schulze, is there any wrong with Castle escs? I guess by 9l u mean feigo?, I would like to use something closer to the top of the pile, i've had nothing but trouble with those in my cars. Does the jolly get to plane quickly on 4s?

Just a suggestion I would go with a couple Neu 1509 2y motors on 6S each and with a set of hydra 120A esc's. Those with a pitched up set of counter rotating 442 props would be quick off the line and amazing top end speed. Over powered? Maybe. With the more efficient motors your run time and temps would be decreased. I write this seeing money not a problem for you. I am sure many would argue this selection but going to the 1512 motors there is not much to choose from that would not yield high amperage while going any over 4S.Comment

Hmm. spoke a bit to quick there. IF you were to go that route just would suggest toning those props down to reg 442's detounged and thinned. Goodluck no matter your choice and remember how much we like video's!Comment
