Hi Doug. Thanks. You are right about the first aid. Clumsy. Good that my wife is a nurse me thinks.😆 No. This is my first attempt at spraying anything like this. That is why I ask a lot of questions. I try to build up knowledge and the courage to have a go. I was lucky this time, so far anyway. It is not perfect by any stretch, nothing like yours, but I am relatively happy with it. Takes quite a while with a 0.5mm nozzle but once you get going, you soon learn that the paint does not go on too thick so the chances of it running are less, I think.
Hello all. I have now returned to Hungary after 4 months. I left the batteries at a storage charge of 3.85v per cell. The reading now on both batteries is 3.85v on 3 cells and 3.86v on one. Strangely both batteries are exactly the same. Conclusion is that relatively new batteries hold their charge very well even if not used for months. I will keep checking them every visit. Unfortunately these batteries might not be used for a couple of years as I found that 2 4s 4500mAH units (using only one at a time with the other supplying balance in the water) were a bit too heavy for the boat and made it low in the water at the stern. I have replaced them with much smaller and lighter 1800mAH LiPo`s. We will see how long they last under load.🤓😉
Well another few weeks have passed and the build is progressing well even though work has taken up most of my time recently. I have started painting now and as expected, finding it difficult. Due to the time limit I have, only five days left, I have had to cut a few corners. Sorry Doug, I will try harder next time. I have decided to finish all of the parts before Friday and take them to Hungary with me to assemble. Not quite what I had planned, but I think there will be less or no breakage. I have added colour LED`s to the navigation lights also. I also have switches operated by the Radio. The Radar turns using an additional geared 6v motor and the water cannon will be working also...I hope. I include a few pictures to bring the build up to date. Trials should be in two weeks so long as I do not leave something important at home. I will add the final build pictures and video the event if I can finish in time.😉
Hello. I am updating the Aerokits PTB at the moment. I have had it for more than 30 years. I have been informed from several sources that it is an ELCO 80 foot. Unfortunately I have mislaid the plans. I am sure I have them here somewhere. If I find them I will try to copy and post here. I have pictured it in a Build Blog if you would like to look and see if it is the same model.😉
So, that is where the 50Cal guns are supposed to be😁 Looks like a similar project to mine. I could sail close by but I would be alone. The local club closed years ago and the pond they used is now a no go zone for boats. The river at my house has no flow as such. It is a tributory of the Danube which has a barrier at each end. The total length, about 15 miles, is a nature reserve and the water level is adjusted to keep it constant.The ripples are caused by the wind. The flip was caused by a bad Captain......probably.😊
Hi The Blacksmith. I am enjoying the build. There is a lot more work in this one than I was expecting. I do not expect a great deal of speed from this model with only a 400 motor, but I will just have to wait for the first trial to find out. I have two other projects on the go but I am putting all of my spare time into this one as I would like to complete before the end of July. I am modifying the lighting on the model to make the blue light flash, add proper navigation lights and deck lighting. Thanks for looking and commenting on the build.😉
The Police Launch is a Krick kit which I am currently building. It is a really nice project but, as usual, I just have to add things. The project is to make the blue light flash. The video shows the three stages of prototyping. The first is the circuit built on a Breadboard. The second part is the actual circuit reduced in size ready to hide inside the boat. The third part is the LED fitted in the incorrect position to show how effective it will be. I have added a trimmer pot to the circuit so that I can select a suitable frequency that looks right at a later date. Thanks to Doug for his help to get started and give me some hints about how the circuit works.🤓😊
Thanks for the help Doug. I only had a 10K resistor between 200K and 4.7K. I fitted it and the result was perfect. Before I did this, I fitted a 220K to R2. The result was a much longer on time and overall frequency. For a Police flashing blue light the 10K is perfect. I have now assembled the finished item ready for fitting. I did a short video of the breadboard setup but it was 60Mb so too big to send Thanks.🤓😊
Evening Doug. I have made up a couple of circuits. They both work well. I have fitted the variable resistor to your design and it works really well. The circuit components are as follows. R1=200k variable. R2= 4k7 resistor. Chip= 7555 CMOS. Capacitor after R2=10uf. Capacitor at pin 5 = 10uf. Single blue LED is 20mA with a 180r resistor. Battery voltage 6V. I have some strange results. The variable resistor works well but strangely, if I disconnect the capacitor at pin five, there is no effect to the flashing light at all. It still works well. There is also no effect if I increase or decrease the value. I am happy with the results but would like to increase the on time a little. Please can you tell me which component should be altered and whether the value rises or falls. Thanks for your help.😉
Hi Doug. It is a 1M pot. This is a single turn component. I also have 5k multi turn, 200k one turn, and 500k 1 turn. I have loads of resistors. 1,10 and 100uf capacitors.😊 The LED`s are 20mA. I have been reading the Tug lighting thread. Interesting. Thanks.
Hi Doug. Still waiting for some components to arrive so that I can try this circuit on my breadboard. One question though. My trimmer pot has 3 contacts. I assume that the middle one is the wiper and the other two are the resistor. Do I connect pin 2, the middle one, to V+ and the other two in line to pin 7. Could you suggest values for R1 and R2. The capacitor in series with these, would 100uf be enough to start and if not enough, how many additional uf is required to make a difference. By the way, the chip is a 7555 CMOS. Thanks.🤓
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.😊
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.😤
[Score: 9/10] 38"/3000g Genesis Capable of 15mph and a runtime of 20mins Single Propellor (2 Blade S Type 35mm) Direct Drive to a 3674 2074KV (2 Blade S Type) Powered by LiPoly (14.8v) 4Amp/h Batteries Controlled Through Hoddyking 125A Water Cooled (25Amps) ESC - Comments: I bought this boat to give me some running time whilst I complete a major overhaul of my Patrol Torpedo Boat and build my Police Launch kit. 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.😊
