Need Help in a setup.

[Morcegolas]

Hello guys, I'm new in fast electric boats, I bought a Catamaran Agitator from H&M and now I'm buying some parts from OffshoreElectrics, like motor, hardware, Bateries, Radio control, and other stuff.

My boat have 810mm ( 32" ) long and I want to know what do you advise, one or two motors? I want a very fast boat but since I'm new to electrics I don't know very much. I'm thinking using Feigao XL motor but don't know witch one, if you can help me setuping this boat.

- 1 or 2 brushless motors;
- Kind of brusheless motor;
- Brushless Speed Control;
- Lipo Baterie(s);
-Charger;

For now is what I need, to iniciate to build my boat.

Thanks.

I've no experience with that cat,but i can give you some advise,just use a single motor setup if you are a beginner FE boater.
Less to go wrong,cheaper,meaning you can invest in better quality electrics etc.
These are great chargers;up to 6S lipo;

I found this setup on the internet for my hull, what do you think?

Motor: Feigao 540 XL / 9 Watercooled
Accu: 1 x LiPo 5S1P TP Hacker EVO 3700
ESC: YGE 120 NAVY
Prop: H & M 42 mm
Top Speed: A bit more than 90 km/h

I want a little more top speed, but if its too difficult I stay with this one.

Waiting for your opinions.

Thanks.

No one?

Seens as noone else is bothered to answer,i'll have a go.
If it was my hull i would go for either a Fiegoa 580 7L or a Neu 1521.1.5D and run it on a parallel 4000 30C 5S Turnigy pack.ie 8000mah total.
Using a YGE 155navy esc or a TMM 16025-3 Race Boat Z-SERIES esc.
Prefrerably the Neu motor. and the TMM esc.

Not a cheap setup but a fast reliable one,if thats what you want.
Asuming the Agitator hull is 33"
Quality gear is always the best way.

the 9 XL on 5S is pushing it. If you want to go with 5S then I would back off to a 10XL. And your capacity is too loo for a single pack, if you went 2P then you would be ok. Try to use 4500 or more total mah. Notice Brod suggested 8000 - you will be glad; long run times and less hard on the packs.

Why not twins? You could go with a pair of 14 L on 5S and be able to get some good speeds. Check out how I set up my 38" Twin Intruder and see if it is fast enough for you. I use low KV motors with high voltage - lower amperage and easier on the equipment.
