Thanks sir

Awesome work sir its a masterpiece

Thank you Neil 

Still some way to go though

Sanjay this is simply a Superb build. .awesome finish. Looking forward to  maiden video.

Fair amount of trials still before the maiden

Just wondering; anyone here have any experience with water cooled ESCs and motors? My query is this: at slow speeds will the water circulate?

I expect (note, only expect ) that at speed the water will get pushed up through the intake tubes and circulate. But a slow speed?

i Have water cooled ESC and water cooled motor...The water does circulate at slow speed as well. The water inlet that I have is a U shaped one on the bottom and suits well even at slow speed. Just keep the water pipes as short as possible.

Thanks Shreekant

The water gets pulled by the prop when the motor is running but boat is not moving??

Very nice build. 
Could not understand motor running but boat not moving.....
may be due to high KV motor, prop spinning very fast but unable to produce enough thrust. 

Thank you Satya

The cooling water is forced through pick-up tubes (brass) through silicone tubes into the esc, motor cooling jacket & motor mount.

The water will flow naturally by pressure when the boat is moving. But when the motor is idling at low speed, there may not be enough water pressure to circulate the water through the system. That was my concern. I could put a pump, but will first conduct trials in the tub and see how it is. The picture in the next post shows the location of the water pick-up tubes

Water pick-up

I don’t think heavy water circulation is required when the boat is at idling/slow speed.
But if the outlet is placed just below the waterline, there will less chance of air residing inside the tube and enough to keep the electronics cool even when the motor is off.  not sure though…

Is it maidened sir?

No. Only waterproof (bathtub) tests

I am happy that after all this time there is still interest in this and I do get quite a few PMs.

As far as requests for plans go, I would like to reiterate that these are paid plans, protected under IPRs. In the beginning I have given where to get these. It is a very nominal fee.

Sir eagerly waiting for the maiden...

Will certainly sail it, when the weather is better, and I have a suitable place. The lake where I sailed the Neptune (http://www.rcindia.org/boats/neptune-(scaled-up)-from-available-plans-in-sunboard/) is too deep and too large - accidents would mean major losses!

Very nice model by Krishna. Somehow never saw it before

@sanjayrai55,
Sir,
Krishna was one of the oldest members of RCI.
An outstanding modeller, esp with boats.
For various reasons, she stopped posting after Feb 2013.
It is time we invited her back!
Regards.
