Thanks Doug. I will try to digest the text and have a go. I will be using a 6v bulb. Good job I cannot blow myself up with 6v.🤓😱😊

Thanks for your help again Doug. It is the circuit diagrams I have difficulty with. I can make the circuit with one. I particularly have trouble with the ic`s as to which terminals to use. I want to use a timer chip to flash the blue light, with a variable resistor pot to adjust the frequency. (Something like that anyway). I will dig out the circuit diagram I used to make a trafic stop signal for a railway crossing. I was hoping to adapt this one.🤓

It has been a busy time at work which means that I have very limited time to build at the moment. All things considered all is going well. I have started the superstructure. The components are requiring a lot of additional work to fit them. I am glad about this as it is all good experience. My sandpaper and files are glowing due to over use. I have found a very useful filler at my local model shop made by Red Devil. It is extremely light and sets in a very short time; ten minutes. It says that it can be painted after ten minutes. Don`t think I will test this. I have fitted the deck and sanded down the hull sides to match. I think the weather is almost good enough to start the painting. I am still a little concerned about this particularly with the use of masking tape. I am worried that the previous layers which are covered by the tape will peel on removal. Can anybody tell me how long to allow paint to dry before applying tape and how long can the tape stay in place. I am using Tamiya tape. I have decided to illuminate most of the lights and will make a module for flashing the blue light. I have lots of electronic components here as I enjoy making prototype circuits. Unfortunately, my love of making these boards is not matched with a knowledge of exactly how they work so I am sure I will be asking for help with the circuit diagram. I have all the components here.🤓 Well that all for now. I am currently constructing all of the deck items. This I find more difficult due to the manipulation of very small parts having `sausage fingers`. Must buy more tweezers!!😊

She looks super Doug. The Swan didn`t look too impressed though. I hope my PTB performs like that. Hope I can do a paint job like that as well. Really nice test lake. I am concerned that my river might be a little choppy at times. I managed to totally flip the Genesis during the trials. Great first trial.😊

Krick Police Launch by MouldBuilder Commander   Posted: 23 days ago ✓ Like This Post   ( 2 )

I have just started to build the Police Launch that I have had for a while. Work commitments have left me with little time lately but hopefully I can get a good run on this one for a while. I hope to finish it by late July which just leaves me enough time to send it to Hungary so that I can test it. The kit is said to be good for a beginner. This would be good as many years ago I built a Patrol Torpedo Boat which took me five years. I am currently restoring this one as well but I think that will take most of this year to complete.😁 I have started by buying the speed controller. The motor is a 400 brushed. Probably not going to be too difficult to keep up with this one. The kit itself is not too bad considering the price, but I do feel that the ABS vacuum formed hull could be of a slightly better quality. Also I am finding the ply wood to be rather brittle. Does anybody have an idea for a good filler to use to fill the chips which will take to acrylic paint. I have prepared the hull and added the propeller shaft and rudder holes. Care taken here to avoid splits in the plastic. Cellotape on both sides before drilling helps.🤓 I have assembled the internal parts which hold the motor, battery and rudder and also fitted the prop shaft.😲 I will start on the deck and superstructure next. An additional note about the kit. The instructions are reasonable but they are in black and white which is not helpful considering they are photograph based with text. I found a PDF on the web which is in full colour. Why don`t Krick supply this. Surely not that expensive.🤔

I have brought the wiring home we with me. I will change the switch and take it back with me in August. I must admit that I thought the stern was a bit low in the water. To evenly distribute the weight, I put in two batteries as suggested. I will try to move the batteries forward to change the centre of gravity.😊

I have now left the batteries at a storage charge of 3.85 volts per cell. I will let you know where they stand when I return in August. The ammo boxes are a great idea. I bought two from ebay at £12 each. They are of super quality. I have transported one with the boat to my boating river in Hungary. The other is here. Thank for all the advice. It made things a lot easier than they could have been during my first uses of LiPo batteries. They are much easier to use now that I have some experience.😊

A short video of the first trial of my Genesis 9000 Offshore Power Boat. This is a boat to use whilst I build others. The trial was seriously hampered by a faulty main switch. The insides must have fallen apart during transportation. I did manage to get an electrical contact to get around five minutes of the trial. The boat ran well but I will have to adjust the rudder to give more movement. Just after the video ended, the boat hit a ripple whilst turning and flipped over. No water entered the hull so all was good, except the switch now refused to work at all. The trial was ended and unfortunately will now have to wait until I return to my river in August.😤

I plan to try it for the first time next week in my local river. I would like to thank Doug (RNinMunich) for all his help to get the boat connected electrically as I have not used brushless before and needed to complete quickly. The boat is on it`s way Doug. Note. It is faster than 24km/h. Ran out of options. The instructions say 55km/h.

I had the colours mixed but unfortunately I could only get 2.5 litres of each. Enough for 100 boats I think. 🤓 I will start the spraying when the weather warms up a bit. That leaves me time to start on my new Police Launch project. Oh and launch and test my new twin hulled offshore power boat.😱

Please can I get some advice on LiPo batteries. I intend to buy a 3300-5000mAh battery to run an offshore power boat model. I will be taking the battery with me to Hungary to use on my local river which I have found is ok as hand luggage properly protected from short circuit. My problem is that at present, I only go there three time a year so the battery would remain unused for 4 months at a time. If I leave the battery with a safety charge, will it last for four months unused or will it fall below the critical voltage. If it is felt that it will not hold the charge, I will have to carry it with me forward and back. Thanks.😊

Thanks Boatshed. I have now purchased a brushless motor which I am making a mount for. I have a feeling that the lack of speed will be dramatically improved. I hope the hull will stand up to this dramatic improvement in power.😊

I would like your opinions please. I would like to paint the main deck and sides green and the anti fouling red. In my opinion, the best matches are RAL6020 for the green and RAL3007 for the red. It has taken me hours to come up with these but I would like second, third and fourth opinions. I have included a sample picture I found on a Google Image search. Thanks.😊

Hi Dennis. I have already purchased a brushless motor which will improve the performance significantly, I hope. One of my concerns for this change was whether the prop shaft could handle the four fold increase in RPM. The shaft is around 12" long. I am considering whether to make a nylon/acetal bush and push it up the shaft approximately half way to try to eliminate shaft whip should it occur. Is this thought to be necessary or am I concerned about nothing.😊

Thanks Jarvo and Doug. I will have a look around. I think there is a place nearby. I will ask my friends who run a garage opposite to my factory.😊 I will have to take some boat pictures with me for a colour match. Sanding to complete today, I hope, and then preperation for sanding sealer and my newly peuchased primer filler. Lots of work ahead. I bought another easy kit to do so I will start a second build blog soon. This one is a Police Launch with an ABS hull. The hope is that I can do both projects at the same time. Doing two things at once is not usually good for me. I have got the urge to get a boat onto my river as soon as possible. I just bought a cheap twin hull offshore power boat to keep me going.I go to Hungary in a few weeks so will send it there to try. I will video the test as it will be the first time in years since I sailed a boat, but a first for one capable of this sort of speed.😱 I will post pictures when I finally remove all of the paint from the MTB. I really appreciate all of the help given. It removes the trial and error which can be costly. Thanks.😊

Thanks Doug. I bought some primer but can use on another project. I will find the filler primer recommended. I bought sanding sealer also for when I am happy with the preperation. I have a 24litre tank compressor and special regulator and moisture bottle in the line. I also bought a second airbrush with a slightly larger jet. I know that you are in Germany, but would I find the acrylic paint in large quantities in a decorating shop? Professional paint outlet? Seen tiny pots in the modelling shop but I would need loads of those. 😊

Thanks Colin. Sounds even better. I will be spraying the whole boat Doug. All I don`t think I will do is the different camouflage colours. I will do the botton in antifoul red with a close match of Pacific green for the rest. Good luck with the removal of the brittle parts. I will not be tackling mine for some time as I have so much other work to do first. I will be watching your blogs with great interest. 😱

Thanks Kevin. A model shop just gave me a good tip. Buy a car screen washer pump for the water cannon on my new project Police boat. They said it would be cheaper than the model pump. Halfords next place to visit. Glad I could be of help Doug. I have bought the 50cal. guns to match the carriages. The assembly instructions are available on the site. Still worried about breaking them whilst removing them from the sprue.🤔I am a precision engineer but this still fills me with nerves.😱

Thanks for all of your help. This is really useful information. I think I will leave the camouflage and just keep to the base colour. Would you paint to the waterline in matt red. I have looked at the shapeways site and they sell Mk 12 carriages in 1:35 scale which I think yours is at 28" over 80`. The gun tub was only placed on the deck for the photo. I have several pictures now showing the correct position. I will alter it and fit just before painting.😊 Thanks again. Peter.👍

Hello Canabus. Please can I take you up on the pdf files of the plans for my boat. I have an A0 printer so should be able to print them full size. I have looked all over for the originals without success. I am learning a lot as I go and wonder, looking back, if I have made a mistake. I bought the 3648 1450kv motor, yes, the beast. Just cannot help myself!!😁 Now that I understsnd these motors a lot more, I realise that it is an outrunner. Do you think I need water cooling and if yes, how is this done when the main outer can is rotating.😊🤔 Thanks.

Started the long job of sanding down today. I think this is going to take a while. During last week I spent the time removing all of the deck parts still attached. The motor, rc gear, rudder, batteries and prop shaft have also been removed leaving the basic hull and decking superstructures. I have visited my local model shop today to see if I can sort out the paint. I have decided on acrylic but the cans are so small that I would need loads. I also cannot find a suitable red for the hull bottom. I am looking for matt. I was also considering making the main colour Pacific Green or similar. I have found Navy Grey which might have to do. If anybody can help with where to source suitable paint in reasonable quantity I would be grateful. I have purchased the sanding sealer and primer. I was considering air brushing the whole project but not so sure now. Any thoughts?😁 I have taken pictures of the progress so far. A lot of sanding still awaits me.😡 I purchased two Mk 17 gun carriages for the tubs. I cannot believe it but they fit perfectly. A picture of these is also below. One last question for now. Should I brush paint, air brush or spray can. The boat is 40" long. Another long day of sanding tomorrow but with greater care as I am tackling the skins. I remember how thin these were when I originally constructed the model.🤔

Thanks Doug. Finally found the Robbe on Amazon for £42 plus delivery. I took your advice and ordered it as it appears to be the only one left anywhere. I will leave the battery until I get nearer to the re-launch. I also purchased the monitors and balance unit. There is no point in starting from total scratch. Thought it safer to follow your lead. Thanks. 😊Peter.

Thanks Doug. That really helps me. I have read a lot about LiPo batteries and now have a better understanding. This experienced help is perfect. I did buy the 100A car ESC as recommended by Canabus but Hobbyking did not have the suitable programmer. I have left a message so they will respond when a new supply arrives. I have looked elsewhere for the programmer but all of the stockists I found do not have any stock. Supply problem? Thanks again for all of your help. A lot of sanding down and painting awaits me for the next few weeks. I plan to drive to Cornwall Model Boats this weekend to see how it looks. I am getting that hollow feeling that I should get a new kit to run alongside this rebuild. Just for a change now and again you understand😁. We will see. Peter.😊

Thanks Doug. Do you have a preference on a charger and is the monitor I saw you mentioned in an earlier post important. Finally, for now😁, would a 5000mAh battery 3s be about right for the 1450kv brushless motor I bought. Thanks. Peter.

Thanks Mark. Is there an advantage in using two 2200mAh batteries in parallel instead of one 5000mAh or is it price. Do you have any views regarding a particular charger. I have never used LiPo batteries before and I read they can be problematic if not used correctly.😊

Hello. I hope I can get a little help with battery choice. I have been reading the comments above and elsewhere on the site, and have decided to go along the LiPo route. I purchased the Turnigy 3648 1450kv brushless motor along with the Hobbyking brushless car ESC 100A w/reverse. I have done a little research on this battery but still do not know the exact battery I should be looking for. Please can you help with the following: What voltage should I be looking for. To have a reasonable useage period, can you advise on a suitable mAh rating. Please can you recommend a charger. Should I have a charge alarm. Should I have a monitor for cell voltage. Are there any other accessories I should have. Thanks in advance. Peter.😊
