Secure the hatches and raise the flags ! by robbob Fleet Admiral!   Posted: 4 days ago
Hi Colin. Welcome to the forum and congratulations on your good choice of model 👍. I bought all of the brass pins I used from a UK based eBay seller http://www.ebay.co.uk/itm/SOLID-BRASS-PANEL-PINS-15mm-20mm-2... I can't imagine that something similar would not be available in Oz, try a good joinery or cabinet makers supply outlet. I mostly used the 15mm size and used, quite surprisingly, a total of around 500 😱. These pins have a tapered head rather than a flat one so that they can be punched flush, or just below the surface of the wood very easily. This is important when pinning the side and bottom skins so that the pin hole can be filled and sanded to give a very smooth surface for finishing. Also, when pinning the thin wood strips always pre-drill the wood to stop the wood from splitting. I'm not sure if CMB supply this type but Javro, who replied earlier, may be able to confirm this. Good luck with the build and please do think about posting a build blog on this site and ask as many questions as you need to. As I discovered, the help and advice you will get will be invaluable. Rob.

Hi Paul. I will certainly video the maiden voyage, I'm just waiting for the lake conditions to improve. Thanks for the good advice as always. BTW. I like your 'noisy fireboat', sounds really good, those transducers are very effective 👍 Best. Rob.

Secure the hatches and raise the flags ! by robbob Fleet Admiral!   Posted: 15 days ago
Having spent so much time adding fittings and detail to the removable cabin roofs and hatches the last thing I want is for them to be dislodged and see them sink without trace 😱! Having used some amazingly strong neodymium magnets to hold the foam tanks securely in the rear well I was confident that they would be more than powerful enough to hold the various roofs and hatches in place so I scoured eBay for some suitable sizes and shapes. I settled on two sizes, 25x6x3mm and 12x6x3mm and ordered 10 of each, more than I need but so useful to have in the bits box. A word of caution with these magnets, always slide them apart and avoid letting them crash together as the impact can easily break them into pieces, as I discovered. Thankfully I have some spares ! For the engine roof magnets I made a couple of small plywood brackets into which the larger magnets are fixed with epoxy and these were in turn epoxied onto the inside faces of the engine room walls. The mating magnets were let into the underside of the roof frame and firmly glued in place after double checking the mating polarity and orientation. An identical method was used for the forward cabin roof but using the smaller magnets. For the removable panel in the centre section over the motor I used a single pair of small magnets on the rear edge only as the front of this panel is held under the cabin door in a rebated part of the floor that forms the threshold of the door. I had to fit a small brass handle in the rear of this panel so that I could pull the panel up and away as there is no other means of doing so without, I made a ‘hook tool’ from some brass wire for this purpose. The floor panel in the rear cockpit is secured on it’s rear edge by a pair of the larger magnets, the forward edge being held down by the towing hook bracing stays. The removable hatch in the rear cockpit floor was also fitted with two pairs of the smaller magnets let into the underside of the hatch and the hatch framing of the floor. One of the brass handles that I that had previously set into the hatch was bent up slightly so that I could use my brass ‘hook tool’ to release it from the magnets hold. So now all the roofs and hatches are firmly secured by the concealed magnets and are easily removable without any fiddly catches or fixings and now there’s now very little chance of them coming adrift and disappearing! The final finishing detail are the two RAF ensigns, one on the mast and one on the stern flagstaff. The ensigns were made by Mike Allsop Scale Flags & Ensigns who was very helpful and advised me on the most suitable sizes for the 1:12 scale of my boat. His flags are extremely well made, excellent value for money and look very realistic when flying and fluttering !! Mike can be contacted at: scaleflags@outlook.com or by telephone on 01476 573331 They are hand made from a fine and flexible silk cloth that behaves like a real flag even in a slight breeze and are easy to fix with diluted PVA glue. The smaller flag was fitted to the lanyard on the mast as described in the supplied instruction sheet. The ensign on the stern flagstaff was very carefully formed and glued so that the flag was not fixed in one place and could rotate around the shaft of the flagstaff as this piece screws into a brass fitting on the rear deck and this will ensure that it will always find it’s own position. A small brass ring was formed and glued to the flagstaff below the ensign so it would always stay at the top and not slip down. So, all hatches battened down, flags raised and ready for action. That’s just about everything finished now barring any trimming and ballasting required and is ready for it’s maiden voyage. I hope that all of you that have been following my blog have had as much enjoyment reading about my build as I have had in the building and finishing process 😁 And a big thank you to all that have contributed so much with encouraging comments, suggestions and advice 👏 😍

Servos & motor having a wobbly by EricMB Lieutenant   Posted: 18 days ago
Hi Doug and Dave, very sorry for the radio silence, day job getting in the way! Really appreciate the input, interesting to hear about your experience with the progress of technology, I guess in using digital RX and TX setups there are different issues that arise! So, to your kind advice - I unplugged the servo Dave, and no difference, which made me think it was the motor. I disconnected the ESC (and hence the power), added a battery input to the RX and all was ok! That made me realise that the power section was the problem, confirmed by a suggestion a fellow model Boater made about checking the battery - instead of chucking out 7.2v, it was giving about 5.3v! Recharged and hey presto - problem solved! Flat battery giving out interference!! Here's the system now behaving as it it should; https://youtu.be/VbGxC0VIo3A Thanks again for all the help and advice - very much appreciated. Regards, Eric

Servos & motor having a wobbly by Dave M Fleet Admiral!   Posted: 19 days ago
Hi Doug I well remember these chokes and that capacitor. I do believe modern thinking is to wrap the low current wires to the ESC round a circular choke, there are never any chokes in the supplied ESCs motor leads. I do recall advice on one of the forums regarding not putting any inductance in the motor leads, not sure if it was Electronize or Mtronic who gave the advice. They both adopted high frequency pulses for control a few years ago and there was lots of discussion as people upgraded their old ESC to a new one. Chokes were quite common in the past but the technology was vastly different to that used by modern ESCs. Are you sure the interference is from the motor? I had a very similar symptom with a faulty servo, very similar to that Eric is using. I have asked him to unplug the servo and see if the problem goes away. So far I have not had a reply so can only guess what might be the problem. Cheers Dave

Servos & motor having a wobbly by EricMB Lieutenant   Posted: 21 days ago
Thanks Dave, that's good advice, I'll try a different servo. I'm hoping it's not this as there isn't much space for a bigger one, but I guess a more expensive one may not cause the same probs?😜

Hi Nick, Yep, 'fraid so! Buy cheap - buy twice! Also the more expensive kit usually has much better manuals and trouble shooters supplied with it which help to avoid 'burn up' disasters!! They also normally offer advice and Help Lines. See also our comments in your 'Best Tx systems for Boats' post. Cheers Doug 😎

Hi Julian Please keep asking your questions. As a newbie you may well not understand everything we explain. You will not be alone so by asking questions there may well be others who will benefit from further advice and clarification. The more people we can interest in our hobby the better and I am more than happy to give help and advice. Best wishes Dave

I am making a Riva boat from scratch. Just a set of plans. Where can I get the accessories to go on this boat . It's 32inches long by 9inches wide.I found the advice from one of your members just now of several coats of varnish very useful.

I have a NiMh on it's way to me as we speak :-) - thanks everyone for comments/advice so far, once it's had a bit of a charge i'll try the various layouts and hope one will at least get the rudders moving

New to hobby by Dave M Fleet Admiral!   Posted: 30 days ago
Hi Larry As Doug says we need to know what you hope to achieve with your restoration? Also can you advise what modelling skills you have so we can pitch advice at the right level. Intially I suggest you use some soap and water to wash the outside of the model and perhaps layout and photo all the loose electrical bits so we can see what you have. I suspect this is perhaps a Robbe kit as some of the electrics seem to be of that genre. It would be great if any member can identify the model Dave
