Cabin roofs were installed and rear deck area created. Roofs have not been glued but taped, which will be done only after the power system is installed.

@ Sanjayrai
The length of the boat is 87 cm and the width at the widest point is 21 cm.

Looks far better right side up.
How did the upside down pics correct themselves in the last one hour?
Once you figure out the powertrain, I'll have to think of some way to make a fog horn for your boat!
Sending you a few white LEDS. Don't have red/green.

ashok baijal

@Iyer
Thanks. Was planning to get some LEDs. Now that you are sending it will be great. Your offer for the fog horn is welcome.

The build will have to be stopped till the powertrain is decided and acquired. Some planning to do for the features on the top deck.

The design inspiration came from this image

Before going any further there was a need for building a "DRY DOCK" (stand) for the boat. So picked up a few pieces of 3mm foamboard and assembled the stand

This is coming up beautiful..Would be awesome with the horn.

Suspending the restoration for
1. Need to get the power train. Would not like to build the superstructure further without first installing the electrics. In my enthusiasm I may paint myself into a corner and then.......
2. Spent a major chunk of my pension on purchase from RCD this month. Will need to wait for next month's pension before ordering the electrics for the boat. So expected delay of at least two months before I get my hands on the motor.
3. Flying season is starting and I would like to spend time in restoring my glow models and go flying after a long long break. Restarting seems to be more tedious than starting fresh.

Will be back on this project after the current flying season.

Hello vc sir   :bow:
Tried to contact you many times,

And then I saw your thread of balsa kits,
I want that kit..
Please help :help:

Returned home today after a long gap. Found that the motor and esc had arrived from hk. The motor has a 5 mm shaft. Expert guidance required on how to connect the motor shaft to the prop shaft. I just checked that hobbyking does not have a 5 mm universal joint. The largest size with them is 4mm. Should I order a 4mm universal joint and enlarge the hole from 4mm to 5mm. Or is there an alternative?

Ashok, I suggest you PM Rooster on this forum. He will make them for you.

Not only me, but quite a few boaties on the forum have got the couplings from him. These are not UJ's, but two machined Brass Collars joined with a flexible Steel Cable - they work very well

Ball pen ka spring. Purana jugad.

Iyer sir: these "jugaads" are OK for boats powered by little CD motors. This is a precision, high-powered motor, and pretty expensive.

Would have to be nuts to compromise on a coupler!

nilharsh

Wow nice build sir,
Waiting to see yatch in her home (water)

Sir,
Ashok is an old friend from over 30 years back.
And he is quite competent to judge how to treat my responses.
perhaps i should stick to pm's.

ashok baijal

Guys!!!!! Cool down. Need suggestions. Every suggestion is welcome. Let them flow. This is not my last boat or the last time I will approach the gurus for suggestions. No idea is small or irrelevant. I appreciate every idea.

Another issue. Is it necessary to install a pump to maintain a supply of cooling water to the motor and esc? If so, any idea for a suitable motor.


sanjayrai55

Ashok-ji, there is no need for a pump. A water pick-up tube with the inlet facing the front is adequate.

Iyer sir is a lovable old shawm (correct spelling) whose post 9 pm posts should not be taken saeriously  >:D

Rooster

Your Motor will need a very sturdy motor mount. Also as mentioned by Sanjayji the pickup at the bottom of the hull are sufficient. I think a different water circuit for ESC and motor always works well.

VC

And I thought that I was the only one who started fights....................keep it up guys! :giggle: ;D

Baijal Sahib, curious to note that you are taking all the trouble procuring Brushless motors, ESC's, water cooling et al. She is a Cabin Cruiser, thus meant to sail at a sedate scale speed of 15 to 20 knots or so. A brushed motor with a geared drive would be more than sufficient for this beauty. She wouldn't require any external cooling at all.

Universal couplings are a must. Rooster makes good couplings (though they are not UJ's), I would recommend them. RCDhamaka often has Boat UJ's in their inventory and it would be prudent to grab them before they vanish!

Thanks for the advice Rooster. I have misplaced the prop, shaft and rudder. Still hunting for them.

VC welcome back. I am totally new to boats. So just ordered the motor by looking at the reviews on HK site. Once it came, i realised how very powerful it is. Well it can go into another boat. By the way, I tried to get brushed motors. Twice I sent messages to Lunar Motors, Valsad, but no reply. I think I had met Hemal Patel, the MD of Lunar Motors. He used to come for flying his rc heli at Mumbai Mahlakshmi grounds. Unfortunately he is not on this forum otherwise he would have been a great resouce for all of us.

VC

Could you let me have the estimated AUW of the craft? I may have a spare brushed motor lying around for you somewhere. Also, what prop size are you looking at?

VC, remember that guy in Lamington Road, Mumbai? He has 300, 400 & 500 series Johnson brushed motors, and shaft/prop assemblies. Reasonable prices and fast shipping.
