17" Hydro Looking for recommendations

[monojeff]

I am getting this hull from hydrojerry & will need to get all new hardware & motor for it.
It's a 17" ABS hull

Need recommendations on running 2s higher Kv or 3s Lower Kv motors.
I'd like to keep the costs down on this as it is just something to play with.

Figured I could run hobbywing 35amp esc
Motor TBD possibly 4800kv
Strut Micro
Rudder Micro
Or was thinking maybe a 21 size rudder might be better? A little more length??
Mini Servo
Props TBD on motor choice


Tips Advice greatly appreciated!!
This is my first electric build other then my 1/10 scale thunderboat which I am in the process of scratch building.

No on with any input on this boat?
Thoughts on the setup I posted??

I've had good luck with the hk motors in 450 size heli's and just ordered 3 more to play with in my mini hydros.

This esc has worked for me and I proved it was waterproof as well.

I have one in my 17.5 hydro and ordered 3 more. Someone more experienced than me will have to help you with running hardware. I make my own or make guessestimates. Go big and trim it down till it works. Best of luck to ya

I have some Minicat hydro parts, strut ,rudder, flex shaft etc, I will dig them out and get back to you. If you use these parts, you can always get spares from Sailr.

I think I am going to go with a 12 size rudder just for a little more length.

Most likely will need a new standoff to bring it closer to the transom.

I am also debating going with this motor option instead.

I used to run a 17" hydro with a Feigao 380 8l on 3s.

I have seen this video boat seemed to run very well!

I am thinking the 3000kv motor should give me a little more to work with.
Also reading that the 4800 motor shaft tends to bend easily.

I am trying to keep my costs down as much as possible on this build so every little bit counts.

[monojeff]

Thinking one of these motors will be a good choice possibly instead of the others
3500kv outrunner

4400kv outrunner

I would obviously need to jump the esc up to the 60amp
ot I could even go up to the 90amp esc

Do you have any videos on this setup?
What boats are you running & what are your temps like?

NO WORRIES you HOOKED ME UP!!!!
Nothing a like a little elbow grease.
I'll get it all smoothed out.

I could have taken it down further but figured the primer seemed to stick pretty good so just smooth it out from there.
I'm not sure if I will strip the bottom paint or not, was thinking I will just light sand and give it a coat or two.
