HARTLEY FLARELINE, NEW PROJECT FIRST TEST
Weather was perfect tonight for a test, so I did the 15km trip out to the Gulf harbour pond (most weed free pond) to throw the boat in. After a thorough under water hull inspection from the marine department, she was off. Everything worked ok except the silicone drive tube which had become enlarged due to soaking in the grease coming out the front of the jet shaft. It was slipping badly and probably losing about 60% of its' thrust. Manoeuvrability is excellent but reverse leaves a bit to be be desired. Steering in reverse is perfect but the thrust is not going forwards enough from the bucket. Might have to build in some nozzles to direct it better.
Smoke air and water are working as well as can be expected, (smoke is a bit wafty, but with too much air introduced it will disappear as it gets thinned out too much to see) I was not expecting miracles as this was a bit of an experiment (modified cheap jet unit with unknown abilities) but at least it shows promise😁. If I can find a coupling which is concentric it will solve the drive problem.
Trouble is, the Chinese insist on making a 4mm shaft, 4.95 (or whatever) which is useless for balance in a 4mm ID bearing for example. Fine for cars, but no good for boats or planes due to balance requirements (it's a mission trying to balance plane props due to this thinking,- they do it with everything) shafts for electric motors are a nightmare at times as the play they build in, can ruin an otherwise good motor. I might have to buy a flexible rubber/nylon universal or a collet style( preferable as these take up any undersize on shafts) to fix it. They included a spiral alloy one with the jet unit which is as loose as a rooster in a sock, and only good for slower things like 3D printers etc. One of these days they will learn how to machine things to fit.😐

- Martin555Fleet AdmiralHi Jb,
Nice to see her in the water.
I am very surprised at the lack of reverse.
Martin555.Liked by Inkoust and Puddle-pirate - jbkiwiFleet AdmiralSeemed to work a whole lot better in the tank for some reason Martin. Possibly due to the coupling slipping, (the squealing is it slipping) Just a bit of silicone fuel tube. I use it on all the boats as it's quiet, self aligning, and lets go if your prop gets jammed by weed. Problem is with the jet, it has a flat on the shaft for some reason which doesn't help the tube grip, and lets grease in causing slippage. I'll sort it eventually,- didn't expect miracles first time out (same with planes) - Almost always some small initial problems.
Motor should be spinning at 15,000 rpm with a 3 cell, but performance is not matching that, obviously,- just piddling along😁 Mind you, I used to cruise like that in the full sized boat, as the Zodiac motor used to suck gas like nothing at 20 knots plus, (gallons per mile, not miles per gallon!)

RC Sailing :- Duck Patrol !?
Policing at the Pavilion Gardens Lake enlist a new "Rookie" from the Buxton Model Boat Club.
Under the watchfull eye of owner and builder Graham Royle, Decoy Duck Donald, turns a few heads while he Ducks and Dives to maintain decorum - !.
REMEMBER - change "quality settings to HD 1080p " when viewing on youtube.

Russel Brothers Tug
My friend is traveling in B.C., Canada, and took a photo of this Russel Brothers tug, though he did not do it especially for me, just posted it on his FB page. I asked if he had any other views but By the time he got my question he was farther on his journey. Still, this would make a nice project build.

- redpmgCommodorethere seems to a great deal of similarity with the tug discussed on RC groups except that their cabin has a flat front

Interesting that the Flo Mac on the Russel Bros site looks very similar to your scratch built one complete with multi chine hull .Liked by Martin555

HMS Victory display model.
Brought another model a HMS Victory this is for display only on a shelf above my television, She was built by a good friend of mine who told me it took him quite a long time to build it, I can believe him as it is a beautiful model.

Tug titch
Super tug and steering wonder. Bought as a kit and made from wood and plastic.
There was no instructions, and without them a nightmare.eventually getting them put the basics into perspective, eventually building the boat.i changed the motor to a 480 and made my own propshaft on the lathe, also a brass rudder, which is operated by mini servo.The esc is a 10 amp m.troniks which works great small but powerful, turns in its own length to port and starboard either astern or forwards

- EscrichPetty Officer 2nd ClassThe software to design the parts is FreeCad, the printer is Prusa MK3s, slicer is Prusa Slicer, and Pronterface to send the file to the printer and control it, the most of the parts you can see in the pictures, have been done using white Prusa PLA, some parts, as the battery holder and so, have been make using orange Prusa PETGLiked by RNinMunich
- RNinMunichFleet AdmiralExcelente, muchas gracias Esrich👍
I'll look out for that software.
I have a stock of PLA, all white!

MORE SMOKER STUFF 2
Trying air injection to break up the water flow. The air pumps I ordered finally arrived a week late but are too small to be of much use. I need a much bigger and faster volume of air to achieve what I want, which is for the water to almost be sprayed out in a mist. Might need to mod the water outlet by fitting fine tubes or stoppers around the inner smoke tube to build up a bit of back pressure, which might be another alternative
Unfortunately, as I've said before, you can't scale water, due partly to surface tension etc (why it either drips or runs out of a small pipe), so to make it fine you have to pressurize/vaporise it at the point of exit (ie garden sprayer) which is the hard part on a small scale. Lots of fun trying to perfect it though, and it keeps me out of trouble, and keeps the brain working - (although it's just asked for a pay rise due to all the work it's been doing lately!😂)
Tip,- if you run both videos at once you can see the difference between this and the last vid. It also breaks the smoke up.

- jbkiwiFleet AdmiralIf only I was that clever Martin! unfortunately he had terminal sickness in 2008😴 He did 40yrs+
of comedy so he didn't have a bad run and made a lot of people happy😊
some of his quotes-
Think of how stupid the average person is, and realize half of them are stupider than that.
Have you ever noticed that anybody driving slower than you is an idiot, and anyone going faster than you is a maniac?
There are nights when the wolves are silent and only the moon howls.
Inside every cynical person, there is a disappointed idealist.
Here's all you have to know about men and women: women are crazy, men are stupid. And the main reason women are crazy is that men are stupid.
The main reason Santa is so jolly is because he knows where all the bad girls live.
Don't sweat the petty things and don't pet the sweaty things.
Weather forecast for tonight: dark. Continued dark overnight, with widely scattered light by morning.
Life is not measured by the number of breaths we take, but by the moments that take our breath away.
Just cause you got the monkey off your back doesn't mean the circus has left town.
