hi mate.
yes the force of the motor starting.
is there not a start mode on the esc? like soft start super soft start etc like on helis?
if not can you program a softer degree of start in the tx....like a throttle curve?
it seems ok once the motor is running just a severely  quick start up.

Sir,
Soft start is one reason,
but on the other hand, I did not feel the importance of the "Fins" at the lower hull.
On a scale ratio it has to be around 4 ~ 5 cm but I made those quite smaller in size.

hi mate ,
perhaps try a temp add-on extension   [perhaps stiff card with tape]  and see if that cures or helps first.

Sir,
I want to slightly over weight the port side to compensate the unwanted torque by the motor. The finishing part is on. working the details.... forgot to have a Periscope  Shocked, and yet to screen print the water level marks and hatch lines.

Maharana.. You continue to awe me with each of your new models and variations in build. Off all the  builds for water two builds that I find most complex is the Submarine and a row boat.
With all the boat builds already with you I am sure the Submarine will be new bench mark for fellow boat builders.

Would be interesting to have a working periscope on this submarine… maybe with a camera.

The finishing is near real.. Awesome let the updates flow.  Clap

Many many thanks Don Sir Salute, and Sreekant  Salute Salute, thanks a ton for the very encouraging comment, I was little frustrated making this submarine, when I damaged the 7ch Rx, I lost all my hopes bringing it to live. I have tested the sub. in the near by  pond (one of my favorite pond) the result is awesome, though I have limited with a 4 ch. the performance is quite satisfactory. No water leaking issue inside the WTC, so I can fine tune the sub. once I have the higher channel Rx. Will update the progress soon.

The boat is awesome.... Hats off for a great build.

BTW, since I am not a boat person, pardon me for asking a silly question. why a sub? does it go underwater? if yes, then how does one control? I mean a heli, plane, car or a boat is always in our line of sight. Is it the same with a sub?

Thanks Pankaj,

The concept of Submarine is very well explained by VC in this thread:
http://www.rcindia.org/chatter-zone/rc-submarine/msg9694/#msg9694

And this first time I am using a 4Ch remote, I mean operating all the channels simultaneously and found great difficulties handling it and now I realize how difficult it is to fly a rc plane. Here I did not attempt to submerge the sub. deep into water but just kept slightly below the water surface.  Swimming pool (clear water view) is the right choice to get nice visibility and sail it correctly. Unfortunately we don’t have a swimming pool in our town.  Giggle

Yes Sreekant, I am looking forward to fix a onboard camera.  Salute
and I never accumulate enough interest in building similar boats again and again, but in this case I think one more build is still required to make an advanced rc sub.

Today my youtube channel (RC boats & ships) has crossed 1 lakh views. The first year I got only 20 thousand views but in the 2nd year it is almost 80 thousand. I am getting enough views from India, and it only due to our beloved forum members. Thanks ….   Salute Salute Salute

Thank you.
My deadline for the story is tomorrow (thursday) morning.

There are as many as rc / model boat makers are here in our forum, like Roopesh, VC, Sreekant, Sanjay, Ghanshyam, Akash, Ved, Amit & Don Sir (UK), all are expert in this field / hobby. It will be nice of you if you contact and take everyone's view and publish a nice article on rc boats and promote this hobby in India.
thanks.

It would be best to list RC India usernames, since the information is sought by a newcomer to the forum.  For example, "Don Sir (UK)" would be "sunk?" on RC India.
