Slightly confused newbie by JOHN Lieutenant   Posted: 7 minutes ago
hi ya J that looks like an Mtroniks speed controller in the pic - does this one have the button on that you press to set it up? because I know what you would need to do is set your trim in the neutral position for the throttle and then go through the procedure of switching on the transmitter and then the receiver and then pressing the button on the speed controller so it recognises where neutral is. I believe some of these Mtroniks are something like 100% rpm forward and something like 75% rpm in reverse. If this idea doesn't work you could always swap the wires over on the motor. (NOT ON THE BATTERY) 🤓 Chinee smokey come out of speed controller if you do dat 😲 John

Painting by MouldBuilder Admiral   Posted: 18 hours ago
I must admit that the painting process is not my favourite. It takes so long and time is always at a premium due to work commitments. I rush it a bit so that the build can continue. I fitted all of the windows into the deck structure and covered them with the low tack film. I then primed, two coats, painted, two coats followed by two coats of lacquer. I am quite pleased with the results even though it is not perfect. I decided not to fit the deck until all of the electronics, including the ESC, battery and receiver had been installed. This is because one of the big problems with this model is the lack of room to work in once the deck is in place. Another problem I encountered was the fitting of the tiller cranks onto the rudders. If the instructions are followed, it is almost impossible the adjust or remove them once the deck has been fitted. I solved the problem by reversing the cranks and bending the connecting wire to miss a bulkhead support. The screws can now be reached from the deck opening. I have now completed the majority of the painting and have started to assemble the remaining parts. Currently I am doing the wiring of the lighting and making a couple of circuit boards. There are a lot of wires involved so to reduce the amount I have decided to us e a common negative. (Cannot remember what this is called right now). There are still a lot of wires and they are mostly coming out from the cabin structure. I have decided to introduce some nine pin connectors to make cabin removal a lot easier. This is quite a big job and will take a little while. I really enjoy this bit. The results add that little bit of extra satisfaction when it all works as it should.🤓 The top search light assembly came as a bit of a surprise. It is manufactured from nickel silver plate and requires soldering together. Even though I am a precision engineer, I have not soldered a box since I was at school. Once I stopped burning my fingers with the heat, I quite enjoyed the assembly even though it would have been useful to have an extra hand and took the best part of today to complete.😤 I can honestly say that I have enjoyed most of this build and even though earlier on I was thinking to avoid Aero-naut models in the future, I have changed my mind. They are very cleverly designed. I expect to complete this model some time in March. That would be the first for me to complete in recent times even though I have two others on the go and one new one in its box ready for a Summer start.😊

Billing’s Boat J-502-Progress by Ron Fleet Admiral!   Posted: 3 days ago
Small boats have less access below the deck. I might use a flat battery pack instead of the quad shown here. The model tested well in the laundry tub under power. Much left to do yet, glad the electronics work. A mini rudder servo is being added.

Precedent Fairey Huntsman by bthart Apprentice   Posted: 4 days ago
I have for sale an unfinished Fairey Huntsman 31, I started it approx 9 months ago as a project with my grandson but his attention has now turned to model railways, subsequently I have now lost interest in completing and sailing it, the boat is approx 90% complete and comes with new RC equipment battery motor etc, I am looking for £250 just to recoup the costs and to put to his new model railway. I live inStoke-on-Trent if anybody would like to have a look,

PS Iona - paddles by Harvey Kitten Lieutenant   Posted: 8 days ago
I decided to build the paddles on my 3D printer, working off the plan rather than building in brass as this should be much quicker... should be! Feeling confident I designed ver 1 & printed it out... and scratched my head a lot to see how this was going to fit together. So ver 2 was much better and almost looked like it would work. Ver 3... same etc. Ver 4 👍 This would assemble looking like paddles. I decided against feathering paddles having talked to a few paddle steamer builders - it seemed more complicated, used slightly more battery power and in 1:36 scale would make little difference to performance. Having built one now I would probably make a few changes but it looks and performs ok. The assembled paddle is attached to a 4mm stainless steel drive shaft with brass bushes. I have recently added some pins to ensure they don't come loose on the lake.🤓

Building the Cabin. Part 1 by robbob Fleet Admiral!   Posted: 9 days ago
The superstructure of the launch is very simple, and from a practical point it was designed to give the crew a large field of view across the river and fast access in and out to deal with emergency situations. Consequently the construction is quite basic and would be quite straightforward if permanently fixed to the boat but this cabin needs to be removable to give access to the battery location and motor. Because of this the cabin needs to be a strong and rigid structure of its own and yet fit invisibly to the rest of the model, it’s also only a three sided structure because of the open access at the rear and that alone will be a point of weakness to the structure. I started by glueing the internal bracing strips to the insides of the deck sides as described in the instruction sheet and some strips that form the base for the sides that sit on the deck, these also needs to be sanded to an angle to sit flush on the deck and also create a vertical face that some further strips are fixed to which meet the inside walls of the deck well. Although all the parts for the cabin are accurately laser cut I chose to do a dry ‘test fit’ using pins and elastic bands to hold the side panels and roof braces together. This 'dry fit' was neccessary because I had previously decided to fit false obeche panels over the balsa sides and floor of the well to get a better surface to finish in the way I intend, balsa does not have any pleasing grain and does not look good even when stained, so I pinned all these panels in place to account for their addition to the internal dimensions of the well deck. When I was happy that the geometry of the side panels and front window panels was correct I glued all the roof braces in place and added some reinforcing fillets to make it more rigid, temporary braces were glued across the front and rear of the assembly to keep the whole thing rigid and square during further assembly. The pins and rubber bands were used to pull in the side panels while the aliphatic glue set. All of this was done with the cabin on the boat so that the correct ‘dry’ fit converted to a permanent fit. Part 2 will continue with the addition of the front window panels and roof.

1950s sea commander refurb. by Colin H. Fleet Admiral!   Posted: 15 days ago
Thanks for all your comments and input. What i really need now is a copy of the templates sheet so that i can cut some new parts to replace some of the missing ones . I have ordered a new rudder, and new plexi glass for the windows. Already in hand is an Mtronics Viper marine 25 amp ESC. 12 volt 7ah battery, Futaba 27 or 40 Mhz RX. Futaba servo. Just awaiting the motor from Doug (RN in Munich). We are going to repaint the Hull in White, Cabin sides in Dark Blue, Cabin roofs in White. The decks will be left as my dad made them, just cleaned and a fresh coat of varnish. the inside of the hull is well sealed already with bitumen (original) which is still allright. Next stage start rubbing down the hull ready for the glass cloth and Ezekote resin. at least i can do this indoors in the warm, workshop too d*** cold. Thats all for today shipmates, more to come, Cheers Colin.

Ultimate Enticement by Puddle-pirate Chief Petty Officer   Posted: 18 days ago
This is a 1984 re-issue of a Lindberg Chris Craft Sport fishermen purchased used on Ebay. Some of the parts where broken and some partially assembled. The model did come with 2 MACK RC motors and some fabricated wood parts, including a template for the aft deck. The interior was assembled from quarter scale doll house items except for the dinette. There are 4 underwater LED bulbs with a dedicated power supply. The running, interior and radar unit are powered by a separate systems from the hull electrics. The second Li-po battery is for backup and balast.

Palamo's Fishing boat by GARTH Admiral   Posted: 21 days ago
Well it's winter here in Hamilton Ontario & I decided to R/C a kit by Ocio Creativo 1/45 scale length 410 mm fishing boat .The model is a static kit so the trick will be installing all the R/C equipment . The challenge is the bulk heads are solid & will need to be modified for motor ,stuffing box , battery ,Etc .

6 Volts of Course of Course! by figtree7nts Fleet Admiral!   Posted: 21 days ago
Captain's Log: The right battery for the job! I found a battery that volts and amp's are just right! The most important thing the right weight! The battery weigh's in at 3 lbs. 1 ounce. Which is just right for the Brooklyn! Give or take a once or two.... But, can be adjusted to trim the water line! The battery is a 6 volt 8.5 amp battery. Which will power Brooklyn for 2.5 hours. Or 1.6 hours with her smoking unit on! Brooklyn will run on 5.2 amps with the smoker. Or 4.0 amps with out the smoker! Unfortunately you live and learn. I tried using the batteries from. Serenity, she's 12 volts 2.5 amps! This was no good, not enough power! Also the 12 batteries weigh too much! So, A 6 volt battery was the way to go! Next is replacing the motor and smoker! Am expecting the motor this morning! Will soon order the smoker! And again she will be completed. For a spring launching!👍

AIR FOR STEAM by Colin H. Fleet Admiral!   Posted: 23 days ago
Small compressors as in car tyre pumps would do it but the drain on the battery would be quite high. A small compressed air cylinder with a regulator could work, but where you would be able to get one I don't know. Cheers Colin.

AIR FOR STEAM by Newby7 Sub-Lieutenant   Posted: 23 days ago
Hello All Thinking out loud when I research steam engines it seams after they are built or after repair they are tested on an air compressor is it possible to set up a model RC boat to run a steam engine with air if so would it be by compressor or a compressed air bottle . If by compressor is there a small enough unit to go into a boat and be battery operated any ideas . Rick

Fairmile D 1/24 Scale Build by reilly4 Fleet Admiral!   Posted: 28 days ago
I am afraid that I disagree with the comments about Doug. They do not reflect Doug's comments or intentions. We are here to offer assistance to those that request it and others that may learn from the comments etc. Doug offers some of the best most practical advice from his experience. A Fairmile D had 4 engines and props. If you want to recreate it as a true scale model then that is the the aim. You are entitled to have one prop, one engine and one SLA battery in your boat. It may plane for approx 10 minutes before it slows and drops off the plane. I had such an arrangement a few decades ago in an old MTB, but have learned from it and moved on. I would not advise this arrangement with all the newer motors, battery types and ESCs available. My Fairmile D has 2 x Speed 700 motors and NiMH batteries. It runs on plane for an hour or more. My newer Vosper MTB and La Combattante III boats have 2 x brushless motors each and the same NiMH battery packs - my choice. Other people use LiPo batteries. We respect all modellers and their quest to build 'their' own models. Nothing wrong with having the best advice available, so modellers can make up their own minds.

Fairmile D 1/24 Scale Build by bikerjohn57 Sub-Lieutenant   Posted: 28 days ago
Don't quite understand why you would want to run four props & motors. One of my fleet is a old Precident Perkasa, in all wood including the hull. Powered by a 12v 7ah lead acid battery a single 550 motor and a three blade prop. As you can probably imagine she is heavy but still gets on the plane to mimic the real thing, will admit the motor did get a bit hot untill I fitted a heat sink with fan cooling. I also have a Hooben Perkasa in injection moulded plastic, yet to be built but intend to use the same set up. Cheers for now John👍
