Hi, Lots of factors to take into consideration, 1 specification of motor 2 voltage to be used 3 size and weight of the boat 4 speed you wish to achieve 5 Current limitations (20A) Besides the above if it is a brushed motor and your limit is 20A I would opt for a propeller of 30mm to 35mm (low pitch). The old rule for Brushed motor is do not use a prop any bigger than the diameter of the motor. the bigger the prop/pitch the more current and a hot ESC. Act with caution, put a 15A fuse in line just in case to protect your ESC. It is difficult to give advice there are lots of unknowns.
Mornin' John (aka Sleepless in Unknown, UK, 😉) That's exactly the jig I found recently for the batch of XT connectors I bought when I finally went LiPo (better than NUTS!). Ref. your 'wall wart' (horrible expression, must have come from our 'colonial brothers. Sorry Ed!)- If the resistor burnt out I'd be very surprised if the rectifier wasn't also damaged. Check the voltage with your multimeter in both AC and DC ranges and let me know the results. Also give me the data of the 'wart'. Input voltage, W or VA rating, output voltage and current. Should all be embossed on the thing somewhere. Cheers, Doug 😎
I do remember that there was a number of variations of this type of tug that used the same hull but with slight changes on deck but I can't think of there names at the moment, they were all called flying ..... It will come to me when I stop thinking about it 🤔
Looks like it could be a Thames Steam Tug, I'm not sure ! I have just acquired this lovely hull and I am not sure of it's build or origin. It is fibreglass and is 57" (1450mm) LOA X 14.5" (370mm) Beam. It has a very basically built superstructure which I don't think is appropriate. I would be very grateful if anyone has any idea what she is and any other information as to weather it was a kit that has been modified. I would love more information as to scale etc. Regards your shipmate. Ballast AKA Alan.
Hi Ron, Thanks for your comments. The small Tug (EMANUEL) is 16" long, scale unknown. No crew as yet, but will try some of my model railway figures. The larger Tug (VALIANT) is 48" and is 1/32nd scale. But using 1/35th scale crew. As for your Gipsy yacht. I'd love a copy of your plans, could it be possible to copy and email. If yes I'll pm you my email address, it's quite possible I have a suitable part built hull that was donated to me at a show last year. Cheers Colin.👍
Two models seen at the Plymouth Gin Factory in the Barbican. Whilst there I had to sample the product and chose the Plymouth Navy Gin, which is gunpowder proof at over 57% and like drinking a single malt compared to a blend. Recommended. We were in Plymouth for the IMASS shipwreck conference the next day, which ranged from Byzantine to WW1 Naval shipwrecks, including HMS Hampshire and HMS Vanguard.

Not quite a build as I found it on Ebay but I have added to it. The barge was build in the 1970's and was very well made. Design is unknown to me but I first assumed it was a thames barge based on the sail layout. I was so convinced I dyed the sails red and built some false side keels. Then I saw another model thames barge, it was longer and narrower with a slightly different sail set up. So here I was a sailing barge with red sails that wasn't what I had thought it was. What else do you do apart from making it fun.
Thanks Dave, you've set me off on another adventure into the unknown but I think I'm learning....do I need the Arduino UNO controller and could I control two motors off it (it doesn't matter if the speed is the same ) . If I don't need the controller ,could you explain a bit more about using the POT (presumably a potentiometer?)
