Hello!
First of all, congratulations on the job. It is excellent.
I am interested in building a hydro like this. Can you send me the plans? Thanks in advance!

Power setup:
-3S 2200mAh (25C ) LiPo (8$)
-Motor 4800Kv (10$)
-Prop is Horracing prop 32mm (8$)
-ESC 40A (10$-cheapest in HK 50A max)

I enjoy building the models. I like the materials. But when it comes to gear I become an cheapbastard
When it rips trought the wather I am happy. Then I come home and study for my next project (the same design but larger scale - Hydro1 racing).

@Volcano:
I can send you my plans. But you must send me your email.
The document is in dwg format (avtoCAD). You can download a DWG to PDF converter if you want to cut the wood by hand.

I blew a 120A esc running 4800kv on 2S, although I was using a 40mm prop.
it should work though if you're mindful of the temperature.

I got that ESC for second season and works fine. I made custom Al cooling pipes on it and they are doing their job like they are supposed to do.
If I burn it. I will just order another one for 10$

I was thinking to use a 4S pack but I do not have room (maybe is that a good thing? )

that's about 78K unloaded, wayy too much, if you have the money it would be a fun 2 seconds!
