Krick Police Launch Trial.

This is s short video of the first trial of the Police Launch. I was very happy with the performance. After 30 minutes of running in fairly rough conditions, I was pleased to note that not even a drip of water entered the hull.
She performed very well but I will wait for a calmer day before deciding on any changes needed to the ballast.
I stopped the run after 30 minutes only because it was very cold. The LiPo battery, 2 cell 2200 mAh, performed faultlessly. Even after being in storage charge for more that 2 years, it still was only reading 3.78 volts per cell after the 30 minutes. My estimate is that it will run for 40 minutes or more before getting close to the lower limit. I was running at full speed for most of the test. My only negative from the test is that Krick have settled for a motor which is at the bottom of the power range. A pity as I am sure that an increase in motor speed would be of benefit to the model.

Looks real nice Peter👍- monitor works well and radar looks spot on, - nice job👍 You can always go up a bit in motor size if you find cruising not to your liking. It does let you stay out longer though, and enjoy it more.

Well Peter,
Finally she hit the water and she looks really good.
I bet you are glad to see her in the wet stuff after the time she has taken to make.
Great work.

One down and many more to go or should i say Finnish LOL!!

VINTAGE RUNABOUT, LAUNCH DAY (RUBBISH VIDEO)

Sun was out, wind was down, so took the boat for swimming lessons. Went very well, no problems other than the silicone couplings trying to screw themselves off as usual, (too much bite and torque) and bunching up to the motor causing friction), (have a possible fix I'm working on for that today) Heaps of power from the 2 - 540 HV brushed motors only running on 3s. Never went much more than a tad past 1/2 throttle which was spot on scale wise.

Very quiet as well, - mind you, couldn't hear much anyhow with a road milling machine working at the end of the pond about 150m away, at around 80db where I was!!😠😠😠😭 Of course it would have to be there today,! something like this always stuffs my plans up, cars, trucks, screeching seagulls, people talking to you while you are trying to make a nice quiet video etc etc. Can't seem to get away from noise. Added to that, the video's crap,- as soon as it uploads to YT it turns to rubbish,- was quite acceptable till then.

Must be the wide format they use, as it's fine in a small screen (ie YT preview) and my computer. Worst thing is, it took an hour to load this rubbish on a fibre connection!! Not loading any more till I get a better camera, "Santa, did you hear that ?"😁

I might de-power it a bit, as it has too much power really,- might put 2 540 45T motors in which will run on 2s nicely with 30mm props (has 35s at the moment) and not be as touchy on the throttle. You can steer this just using the throttles it's so bitey. Spins on the spot like a jet boat as well. Stereo worked well, but the IR remote doesn't like working too far away in bright sunlight, (have a separate vid, but YT would give a copyright warning, so I won't put that up) The vid is garbage, but you'll get the idea😁

View from on board my Cutter sailing on the Pavilion Gardens lake in Buxton last weekend.
The video is running slow at 70% speed as I think it looks better at that speed.

Hi JB,

I can't use the lack of a wind indicator as an excuse 🤔. I still think the main problem is the nut holding the tiller 🤣😂

Continued ----- re . My Gaff Rigged Bristol Pilot Cutter - " TIKI "

Still working on a bit more keel weight and trying other rudder profile surface areas to improve turning ! - I think the last two videos may illustrate the need for further improvement in these areas.

Hi Mike - I really do like that idea ! - I tried a small motor/prop in my "wee nip" but converted it back to standard sail power - interested to know details of your pump though . 👍

Hartley cabin boat on trailer

Short vid taken by a friend recently, of the model, towed by the RC scratch built Jeep -(taken with his tablet, - a bit shaky but he is over 80) I probably shouldn't have been doing circles around him, but we were doing this in a carpark behind his apartment, (magic location by the way, right on a marina.) Had trouble finding reverse due to the EL Cheepo ESC,- have a new one coming. Jeep uses a geared 550 motor on 3s LiPo.

Boat is featured on waitematawoodys.com today as well, with all the big boats,- quite a privilege, as they don't often feature models! Lucky to have had my ST and HSL on there in the past also, as they were models of ex NZ RNZAF boats which were being featured.

Hi JB,

I'm afraid my days of building real boats are long past. I have difficulty in finding enough strength to perform even the simplest tasks, Alice has to come to my aid for almost everything these days. I was very pleased that I managed to finish the rigging of my latest barge project a few days ago with only the slightest intervention from her -and that's a model!. Actually the only time I ever built a boat from a plan was when someone gave me a part built Wharram cat. The rest of the time I built on the old adage of if it looks right, it probably is. And, blowing my own trumpet, it always seemed to work for me.

Cheers, Nerys

Hi Nerys, you're doing well to do what you are doing still under the circumstances, and you are not just sitting in a wicker chair staring out the window. Your models are great and a credit to you, and you are obviously enjoying them. I'm the same (re - if it looks right.......) as most of my models, (boats and planes) are scratch built or highly modified kits or resurrected and improved bin jobs from other modellers.

The only model boat I've built from a proper plan, was my Vic Smeed MTB, the rest have been from drawings from model magazines. I built a 15ft delta hulled racer in the late 70s using the 'looks right' method, and powered it with a 75hp outboard. Managed to get 50mph out of it, and it handled quite well. Blew the motor up before I could refine it unfortunately. As kid we built 8ft skimmers, powered with a 10hp outboard which were a lot of fun as well.

I've enjoyed restoring 5 small boats (plus a f/glass clinker sailing dinghy for my son) and completely fitting out my Hartley from a shell, but the price of materials is getting prohibitive these days, and approaching the price of a small new car to build anything around 20ft. My 15ft day sailer for example (built 1986) would probably cost around $12,000 to build today complete. Not a lot of home building these days unfortunately due to the cost,- cheaper to buy a second hand boat ready to sail or motor.

I think we are lucky to be able to build from an idea without a plan and have it work, as many people are not as fortunate. Perhaps boating experience gives you an idea of how things should work. We have a top boatbuilding company here who started building fantastic launches, starting with a 'looks right' half model,- taking measurements from it and scaling them up. Has worked well for them since the 50s

Stay Safe.

Scratch built Bristol Channel Pilot Cutter

A change from Maid Rosalind Thames cruiser blog posts! This winter I added a removable keel and rudder extension to the Bristol Channel Pilot Cutter I built in 2017. I wanted to produce a hull that was truly accurate above and below the waterline, and with the correct lead in the keel and in scale winds she sailed ok, but to get a model to sail realistically, you generally have to add a lot of weight deep down. The last picture shows that for regular display, the ugly keel and rudder extensions come off and the stand's extended legs unscrew. She stands 6' 2" with her new keel, and 4' 6" long. The trials were successful. She sailed beautifully, even tacking those overlapping headsails flawlessly, which is generally quite hard to do with RC! I have up to now only posted blogs as they happen, but I have full documentation of this build and can start a blog for it after Rosalind is finished, if it's OK to publish something from the past. I added a teaser build picture!

Edward M. Cotter

Today's weather was great for R/C model boat running & sailing in our favorite water hole the Hamilton Bay .The real Edward Cotter is a fireboat based in Buffalo New York & is also one of the oldest fireboats in the world . Near the end I almost had a disaster where I just touched the Ferry boat because I use a I-Phone to record videos & also run the models transmitter & some times I get distracted .

brave borderer 4th sea trial!

Typical yorkshire weather, after 5 minutes it chucked it down so had to make a quick retreat. used just one 2200 3s lipo for now but need a bigger lake/pond really as can only give full power for 3-4 seconds, so stop -go is not good but was hoping to get some good photos-videos, but the rain stopped play till another day.
Edit, forgot to mention. most of run on centre prop only. the last 5 seconds or so is full power, well nearly.

Looks good Roger,
Whilst the comments on paralleling LI-POs are correct. I have never had an issue. I have used two identical cells and fully charge each separately until the charger cuts out.
Would never try two partially discharged cells as then the current might flow from one to the other creating the overcharge rate problem
Recently decided that rather than use two cells, why not use one at once? This reduces weight and eliminates the concern.
Think you need a larger pond! Glad to see the weather is consistent with my memorys.

Brave Borderer 2nd trial, new battery

I've replaced the old 6v sealed wet battery with a lipo 3s,11.1 volt 2200mhz, 100c spectrum smart battery. so the 1st run was cautious i just fired up the centre prop to see how she performed, well i was surprised at the turn of speed she had on just 1 prop, and how well she planed, it was a little awkward filming and controlling the boat by myself as i was the only one pond side. this was not without mishaps though, see 2nd video
After checking the boat over she was found to be unmarked and no bits missing, not bad to say she hit the pontoon at full speed, took off and plunged back in at the other side.
So the second run i started on the centre prop and then opened her up on the outer 2, she shot forward and immediately stalled, dead in the water. luckily i could reach her with the ponds barge pole to pull her to the side. i found the fuse had blown , i had fitted a 20amp mini flat fuse, i didn't have a 30amp only another 20amp which blew just as quick, upon opening up the outer props.
any ideas anyone or will a 30amp do the job, or a 2s battery? help any suggestions considered.

Hi Ronan
Thanks for your input.
Its starting to make sense now.
I bit the bullitt and bought a lipo battery and charger. I ended with a spectrum smart 2200mhz,3s, 11.1v,100c.i had a choice of a 30c but thought it may not be man enough for 3 motors so looked at the 50c, but was out of stock, so i ended with the 100c it was the same price as the 50c anyway. The charger was a spectrum smart type to. This monitors the battery and hopefully does everything automatically.
Once again thanks for your help and encouragement

Hi Roger,
You are learning well! A similar road to the one I travelled a couple of years ago.
Hard to see the fuse block on my Brave now, but here is one am assembling for my next project. Got my fuse blocks off Banggood, they offer both 4 and 6 fuse ones.
Used a 6 on the Brave as wanted a fuse per motor, currently using 30 A capacity. Should protect the 50 A ESCs. Bigger fuses and even re-settable ones can be fitted into the block if warranted.
The home made buss bar and battery connector are visible.
Hope this helps.
Rowen
100C should be more that adequate, mine is 30C. You should be able to drive a welder with it too!
