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!!

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😁

Found it would fit in the paddling pool, so being a nice sunny day, thought it was about time to wet its' bum. So bright today, smoke and water was hard to see, (I can't win ! - either too bright or too dull😐) Anyhow, everything works well, (just need to adjust the rudders,- bit of right needed), plenty of grunt (only about 1/2 throttle max here,- mostly just 1 motor - don't want to bash the paint off !)- bit hard to control in a small tub !,- needed someone to hold it.
Next stop, the lake !, after I modify the launching trolley and making a stand. Unfortunately can't demo the stereo working due to new YT music censoring rubbish. No different to sitting at the beach with a radio, but YT warns you about copyright which is just moronic.

Hi Bill, wasn't game to try that, kept trying to bash itself to bits. Hopefully be out to the pond soon, just sorting the launching trolley out. Restrictions make waiting for things (sponge tubing in this case) a pain, slows every simple 5min job down to days.😐

Hi Peter, wasn't room for a heck of a lot of testing really, and nowhere to tie anything to that wouldn't have damaged something. The music is a problem because of the algorithm YT uses. seems to pick up the most obscure music (even old rare 70s stuff) and starts warning you about copyright . Don't know how it does it, but I've even tried Cuban music, and it still picks it up (mind you who's going to have a go at you from Cuba😁) The bit of rubbish stuff I made on a free beat site got past it though,- strange ??
Even if you play the music,- (obviously in the model vid) it will still pick it up,- and if someone is parked next to you in a car with the stereo going and you are recording something else!! This is just beyond stupid, as you are using it for private purposes and not being paid for doing it. Seems like the whole world is - 'cant play this, can't record this, can't video this, can't have kids playing on swings, might hurt themselves, can't make noise' etc etc. The govt can record people without them knowing, but you can't !!! All about control. I'll do a vid on the water with music - "I was just videoing someones' boat sir" and see what happens.

Ever felt sorry for those Philipino static models you see all over the place? Well I did and bought this launch from a charity shop in Didcot for a fiver. I reckoned that the fittings were worth that even if the change to working model failed. Fortunately, the model floated about right as it was and I managed to save a lot of weight to allow for the added weight of motor/batteries/ rc gear etc.
The project has not been without its problems but it should be finished and ready to maiden within a couple of weeks. Not sure that I would do this again but it has been interesting......... I intend to mount it on a boat trailer rather than a stand. Report more when she is launched.

Scratch built motor gun boat from Bangladesh.
Tried my best to upgrade it into a brushless one. First attempt was brushed and it was kind of a pain in the ass.
It runs far better now.

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.

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.

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.

Transferred this from my build blog. Quick vid of the starting - sound/ smoke /water exhaust sequence (water not plugged in, but can be started a few seconds later than the smoke). Smoke starts first to heat up, then air pump (timer for 5 seconds delay) then water (TX switch,) - could put in another timer to make it fully auto, but enough spaghetti there already. Also handy for future water cooling if the motors need it (fan cooled so probably not needed.) Left stick is held over to start the sequence, then released to turn the smoke and air off.

Finally had a chance to do a test on Pilot 40 project that was my lockdown stay home project . Change the props to 50 mill.4mill.threaded & now I have right prop & left prop Replaced the Sabertooth speed control as it was to hard to control with my Airtronics transmitter used a standard Hobby King speed control changed the wiring terminal block to a larger size as the one I first used was to hard to put wires in it . I always have trouble with mounting so glued the motors in with some goop & there just fine now

Fitted the new 550 45T brushed motor as a replacement for the ancient and slow 70s Graupner monoperm. Goes a lot better now and has a decent speed range. Handles and rides quite well for a skinny boat. Prop is a Graupner 40mm 2 blade (don't know the pitch, -fairly fine) Using a 2200mAh 2S LiPo battery which probably gives around an hours running slowly, or 30 mins of hooning around.
Battery was only charged to 8.25v and ended up at 7.7v. (45%) after about 3/4 hr. I'll probably fit a Hobbywing ESC as well, for a bit better reverse action, as the El cheapo car one is a bit slow finding reverse at times.

Part 1. ideal conditions; nearly 30°C, cool Bier at hand😜
Sea Scout built by Dad in the early sixties with a Taycol Target and 6V lead acid wet cells (very wet😡). Renovated and dragged into the 21st century over the last several months 😉
See Build Blog 'Sea Scout 'Jessica'' for details!
Motor: Propdrive 2830, 1000kV, 30mm 3 blade Raboesch prop. Quicrun 16BL30 (30A) ESC with BEC.
Tested with 3 battery types, all started with 99% measured capacity-
1. NiMh 4.2Ah 7.2V, nom. 408gm.
Result: Speed sedate (OK 😉scale river cruising!) No planing.
Max current: 3.6A
End status V / capacity left: At end of short run ca 3 mins. 7.78V 99%.
2. 2S LiPo 4.0Ah 7.4V nom. 257gm.
Result: Speed still sedate but due to lower batt weight at least the forefoot came out of the wet stuff! Max current: 4.1A
End status V / capacity left: At end of short run ca 3 mins. 8.25V 93%.
3. 3S LiPo 4.0Ah 11.1V nom. 315gm.
Result: Now we're getting somewhere!!😁
Good speed, manoeuvrability and planing 😊 Max current: 7.5A
End status: 11.95V 74% after several long runs, ca 20 mins total.
Estimated (extrapolated) endurance on a 4Ah LiPo around one hour - mostly 'full bore' - 'Pedal to the metal man' 😊

The competition!

Final run. (Beer was getting warm😁)
Cap'ns log entry:
Boat dead-weight w/o battery: 1.8kg.
Spray rails to be added!😲
Slight list to port to be trimmed.
Rudder servo to be reversed!!😲
Keel protection to be added: some scratches and flaking from stony sloping shore 🤔
Summary: much as expected👍 Forget anything less than 3S.
Anyone want to buy a batch (4) of new 2S 4Ah 45C Lipos? 'One careful owner'!
Happy boating people, Cheers Doug 😎
PS Many thanks to Camera girl Gisela 👍

Hi Will,
The videos were all taken at stage 3. 'Now we're getting somewhere' with the 3S LiPo.
As depicted in the report there wasn't anything worth filming on either the 7.2V NiMh or the 7.4V 2S LiPo. Plod plod boring! I wasn't really surprised. I just wanted to know 😉
Cheers, Doug 😎

well finally got there. she sits a little low in the water, but evenly along the water line. this was with the battery central to the hull. when powered up the centre screw alone moved her quite serenely and was very manoeuvrable. when power was added to the outer screws I would say she didn't plane well as she wasn't going fast enough. even with all props on full power, I think also she is to heavy and the battery too far forward.
So to remedy this I moved the battery back a compartment, positioning it over the 3 motors , it was a tight squeeze, but fitted just.
This sat the stern down a little and the bow up and gave the impression of planeing, she still not fast enough though. the scale speed still doesn't look right.
I'm going to have to have a rethink on this one. having said all this though she looked well in the water if i say so my self.

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!!
