📝 Cigarette hull (Kingston Mouldings)

Hi Shipmates,
Mini update as I seem to be bouncing between two builds a the moment.
the other is my PT boat.
https://model-boats.com/blogs/43841#86909
Picture of centre console in cockpit and the the other is the painstaking shaping of the outside of the cockpit to merge the seats with the bodywork and vent. Will also need to do the same on the other side.
Sorry about the dust!
Regards Roy

Hi Shipmates,
Roughly fitted ESC in then add some LEDs to the exhausts' powered by a 3v battery box and switch, 'Holy Smokes Batman', originally wanted to fit them from the inside but the restrictive room meant I could not, so need to block the exhaust holes. I feed them in from the outside and glued them with expanding gorilla glue, nice and bright. Also drilled holes for cooling tubes from the rudders. (not shown)

Hi Roy, no need to apologise, i guessed that you would reply when you had a chance.
Yes, the skegs will cause a slight drag, but considering how close the props are to each other, they're most definitely needed. Will 👍 Like

Hi Will, Sorry for delay in replying! About 1mm clearance between props a brace between stingers, (I know it will cause drag) stops the props (40mm) possibly touching under the forces applied to the stingers in turning etc. initially they where only 0.5mm apart but the brace holds them at 1mm.

How much clearance have you got between those props?
It doesn't look very much at all. 👍 Like

Hi Shipmates,
My ESCs come without connectors, my preferred connector for this ESC is a 6.5mm Banana type as the wire are thick, unfortunately the motors were prewired with 4mm connectors which out of laziness I did not want to remove, also a 6.5 would have been too big.
So the solution was to make an adapter (I know more resistance losses) luckily the 4mm fitted into the 6.5mm's wire socket, so we have a 6.5 female on the ESC connected to a 6.5mm male connected to a 4mm female. (made 6 of these)
Hey presto!🤞 and one burnt finger do to carelessness while heating the shrink down.
I know some aspects of the ESC cable lengths are important I think it could be the cable from the battery to the ESC (where the capacitors are situated) has anybody got the lowdown on this.
Regards
Roy

Hi Shipmates,
And now for a boring but essential part of the build,
yes 'the boat stand'. I just hate making these, I put a bit more effort into this one, It is designed to flex so will sit on uneven surfaces, eg grass banks etc.
Cut ends from 11mm waterproof ply, added some foam pads, used rightangle aluminium, for sides , glued with Gorilla glue.
Not sure if it will need more support!
Sorry about the crumbs.
Regards Roy

Hi Shipmates,
Martin guessed that it was going to be a Batboat and was right.
I got fed up with normal boats, so I thought I would do someing that was pure fun, that I could design myself.
Still lots to do, windscreen, steering wheel, dashboard, water cooling, wire ESCs, Painting and logos.
Regards
Roy

That's one very busy rear end Roy. Nicely done👍
Fingers crossed that it doesn't all fly round Batman's ears on the sea trials😮🤞 "Pond rockets" are not exactly my 'thing' either (although I accidentally turned my U25 into one😁) but I really like what you are doing with this one! Hat off Sir, well thought out and executed😀 Can't wait for the trials vid. Holy planing Batman🙈 (This Bat Mask is ruining my hairdo!🤔) 😁 Cheers, Doug 😎 👍 Like

Hi Shipmates,
• Have taken off trim tabs and increased the angle on the transom pads re-
affixed so they are clear of the water in their neutral position.
• Added fixing points for servo mounting board/battery box
• Foamed front compartment to make the boat unsinkable, also filled gaps
between seats and cockpit sides.
• Added ABS top to the compartment hatch to enable me to tape down the
ABS area without damaging paintwork to provide a water tight seal.
🤞 After reading an article on using the rooster tail effect to lift the rear of the boat in a similar way to a trim tab. I have designed a deflector plate to hang over the props thus when the rooster effect occurs the force of the water hits the plate (riding surface) and lifts the stern slightly.
Regards Roy

Hi there Shipmates,
Added a brace between stingers, I know it will cause drag but its better than the props (40mm) touching under the forces applied to the stingers in turning etc. initially they where only 0.5mm apart the brace holds them at 1mm.
Put servos in positions. (metal geared digital 20kg)
Added padding to cockpit seats, centre console under way.
Added shaping to main compartment hatch (a bit like Beetle wings). filled with foam, so hatch will not sink.
Regards
Roy

Hi Shipmates,
Thanks for comments, Like always you don't know how a boat will perform until its on the water, then you realise what you have done wrong or right. Its funny that Windermere was mentioned as I live about 30 miles away from it. Shame it has a speed limit of 10mph, if anyone need a big lake the one at talking tarn is 65 acres. and there is a model boat club there, https://www.facebook.com/groups/CalisleMBC/ but no shelter close by. "Talkin Tarn Country Park lies nine miles east of Carlisle and two mile south of Brampton on the B6413 Castle Carrock road. There is a 65 acre lake set amid 120 acres of farmland and woodland. The tarn is an ideal place for active recreation or a quiet stroll through the mature woodlands." Note the servos were dirt cheap from Amazon at £1.99 https://www.amazon.co.uk/dp/B07W47TWY5/ref=dp_prsubs_1 or https://www.amazon.co.uk/dp/B07W47TWY5/ref=dp_prsubs_2 Regards Roy 👍 Like

Hi Roy,-Starting to look pretty mean at the business end! I have an old 40" Prather DV hull I'd like to do the same to. Used to have an OS .45 FSR in it years ago, but electric has unlimited possibilities nowadays. Just bought one of those JX servos to try as a sail winch, they seem quite a nice servo.

Hi there shipmates,
'Nut Screws Washer and bolts', yes there're all in the transom now.
Had to put the bolts in backwards for the turn fins as the space restrictions inside made it near impossible to use a spanner or box spanner inside the hulls stern.
Added side panels to the cockpit area. Build in seat started, not shown but reinforced rear access compartment.
Regards
Roy
P.S. the rudders are vertical it's an optical illusion caused by my camera!

Hi there shipmates,
Due to the propeller shaft spacing of 41 mm apart, I had to make a engine mount, and angled it to a line the two flexi shafts with minimal bending.
I will not cut the flexi shafts until I fit the two contra rotating propellers, that are on order. 2x 40mm diameter x 18mm pitch.
Starting on the cockpit area, I lined it with wood and built a seat also from wood, waiting for some bolts before mounting the rest of the hardware to the transom.
