1.1M Cat setup help

[Brod]

2 of these motors would make a great twin setup in a 1.1M cat,good quality motors.
I have a couple i run in hulls,they are tough, long lasting motors

After a lot of research and lots of PMs (thanks for your help and patience Jay!), I decided on the Feigao 540XL as the motors for this boat. Battery will be a lipo, contrary to my liking. But I can't afford to pay $500 for a set of A123's. So lipos 6S 5000mAh and modified (water cooling / waterproofing) cheap 100A ESCs off ebay. Strut still undecided...

Awesome, keep us posted!

Another question: I decided to go with wire drives instead of the flex shafts.
Will a ɸ2 mm diameter steel shaft do tho job? Motors Feigao 540XLs.

[norbique]

I decided on the setup.

Motors: Feigao 12XL
Batts: 6S 4500mAh lipos
ESCs: 100A Mystery modified - watercooled and waterproofed, 5 more 1000uF low ESR caps added
Wire drive: ɸ1.5 mm steel wires
Props: K45, x447 L+R, or K51

Thank you all who helped me to decide!

OK, I stumbled across this: (Scorpion and Hyperion joined their forces)

and now I can't decide whether to stay with the 12XL's or to switch to these.
I was told these scorpion motors have higher power than the 540XLs do. Can someone comment on this?!
What also makes me go for the outrunners is, that they have stator laminations not only copper like in the Feigaos and if it burns up it can be rewound. And it has 10 magnet poles VS the 2 poles of the Feigao.
Only con of the outrunners I can think of is a bit troublesome cooling.

Steven of OSE is going to carry a monster 63mm outrunner with water cooling. I looking forward to that to power my 1.4m mono project.

[norbique]

Are you referring to the littlescreamers motor?

[Himalaya]

Yes. I would call it a Bigscreamer instead. still have a bit worry about it's cooling effect though.

At the end I went for the T600 1400KV Turnigy outrunners. They are good quality motors.
Batteries will be A123's. 7S2P times two, one for each motor. Roughly equal to a 6S 4500mAh Lipo pack. A little bit low capacity, but I don't want to go with Lipos, nor can I fit 3P setup in the hull. :)
ESC still just a plan, SkyWing 150A heavily modified. (watercooling, waterproofing, cap banks)
