Hi, I am new to powered rc boats having previously only had sail boats, I am building an aerokits sea rover and really have no idea on the motor , esc , batteries , prop size etc . Is there somewhere I can find out what will work with what . Is water cooled worth thinking about ? Any advice would be gratefully received. Thanks Simon

Hi Simon

We use the Hobbyking 35mm brushless 3639-1100kv motor(no water cooling), 60 Amp car ESC (HK-60A SL) with the program card ,Zippy Compact 3300.3S.25C and prop 2 blade 40mm.

I am using this setup in my Sea Commander, but, I use a 5800mah battery as it is a little bit bigger boat.

I also have the little Sea Hornet with a 28mm brushless motor.

I have the Sea Rover, Sea Hornet, Swordsman and Sea Queen plans on PDF.

Hi Simon.
Just like Canabus I have a few of this type of boat, all with brushless motors.
So just to confuse you, 😀 here is the Sea Rover I am building at the moment, the motor is a Speed 600
I have a few photos of the build if you need them.
Why did I choose a Speed 600, it was in my box of bits 😀

Thanks Alan, your boat looks really nice, why the 2 holes in the fore deck?
I have only just started the build I will post some pictures later.
I see you have a water cooling jacket on your motor , I will be buying a new motor as the only power sources I have are sails , this is my first motor build. Is it worth getting a water cooled motor .

Hi Simon. The two holes are just so that I could pour some Z-Poxy in after the skins were on, helps seal every thing.
The motor is a brushed motor, and I had the water jacket, so it will be fitted, don't think it will need it though.
If I ever change the brushed motor for a brushless set up the water cooling is already there.

Alan,
Where are you positioning the batteries? I presume under the cockpit floor, if so how do you seal the cover?

Hi Simon.
The batteries are laid at each side on boards and will be held in with Velcro, I will be able to position them as far forward as Bulkhead B2 and as far back as B4 depending on how the boat rides.

The centre of the cockpit is removable to get at the servo and batteries. The cockpit floor has been raised to allow for servo and batteries. (115mm from top corner of cockpit window frame to the planking)

Cockpit roof is removable, note pin on window frame and bolts on cockpit sides.

I am hoping not to get too much water in the cockpit so it should be OK.

With this kit you need to dry fit all the bulkheads and cabin sides to make sure it all goes together before gluing. If things don't look quite right after you have done this, look at bulkhead B2
