This video follows on from my earlier post. I changed to running on a 5 cell lipo (18.5 volts) and I am very pleased with the Improvement over 14.4 volts Nicads. (Edit sorry Nimh`s) I put this link into my reply on my previous post but it didnt work as a hotlink so I am posting this.
The boat isnt quite flat out here due to the difficulty videoing and steering.

HI Les
What a bummer. Bread is not good for wildlife and certainly not for props.
Hopefully your motor should be OK as long as the wires are not burnt. if you have a multimeter you could check the insulation between the shaft and each winding using the highest ohms reading. it should be high, if low chances are there is an internal short. A quick check (on a lower ohm reading) between windings should give similar results between every pair, again any variance may indicate an internal short.

I am just building one of these on a wood hull, I notice you are running a single motor. Could you advise what motor you are using plus what prop please? Thanks Andy
Built from a kitishack kit 56" it runs on two Hobby King 750kv brushless motors I used brake pipe to make the motor cooling coils two 200a water cooled esc,s, I got the 5mm shafts & 42mm brass props and couplings from SHG models the power is supplied via two 14.8v lipos this is a really powerful boat
I think with two beefy out runners, 42mm props on 14.8 lipos it should be a very powerful boat. However I like big boats properly engineered. Well done. 😀
Northsider built from a Tyne Model kit
History M.T. Northsider & M.T. Ironsider:
Completed April 1967, at Richard bunston Hessle for the Lawson
Batey Tug Co. Ltd., at a cost of £106,500. Then chartered to the Tyne & Wear Tug Co. Ltd., working on the Tyne for harbour towage. Also visiting other UK and European ports during many coastal tows. After a long and eventful service on the Tyne, sold in 1996 to BaltagI Pilots in Bahrain and renamed 'BaltagI 6' there it remains in service today. M.T. Ironsider Completed September 1967, a sister ship to the Northsider, also chartered to the Tyne Wear Tug Co. Ltd., until 1992. Then sold to Proodos Maritime Co., Piraeus and renamed 'MegaloharI 12' still in service today.
Both tugs are similar to Alexandra Towings Tug, 'Sauria' which, was based at Felixstowe, UK. .
Ahoy
Here is a display model I built it is the late great RMS LUSITANIA scale 1/350 built for show only it took me 7 months to build a one of a kind kit something you don't see everyday built from a kit mostly scratch built did not like some of the kit parts so I made my own.
This was a precedent 49 inch kit that I made during last year. I wasn't at all Impressed with the kit. The precut plywood parts were cut with knife blade tools and the tools were obviously past their sell by date. The shapes were very poor. if I make another kit I will make a point of looking for a laser cut hit.
Having said that I am pleased with the outcome.
The bit I can't understand is that I was running the boat on 14.4 volts. I did nothing yet it cut out on the lipo at 3.3 volts per cell which would equate to 16.5 volts. if it had been programmed to do this it wouldn't have worked at 14.4 volts. its as if it had auto programmed itself.
HI Les
There are default settings in most ESCs and they change when you select a different type of battery. if you selected LiPo it recognised 5 cells and auto set a 3.3 v cut off. My latest LiPo 5000 suggests a cut of voltage of 3.4 volts so I suggest you look on the battery cover to see the recommendation. The higher power batteries are very low internal resistance and I believe this is why they suggest a higher cut off.
So yes your observation is correct
This was the 1-35 scale plastic model kit and converted to RC 3 props 2 working port and the starboard the centre is non running. Due to weight I used a 11.7 lipoly battery so it's fast but the running time is only about 20 30 mins
It won best in show in the navy boat section at our club due to the detail and the figures so can't be bad
Custom made rotating radar & gun director, flashing LED spot/signal lights, smoke system, RAM sound system "WHOOPER", RAM Bilge pump. Two guns are set to follow the gun director.
This model of a German North Sea FishingTrawler was built from a Graupner kit in January 1974. The crew are South American, the dog Welsh the owner English and her home port is Maldon. She is powered by a 6volt 400 motor coupled with a Viper 15amp controller and my Spectrum radio outfit. The 6volt 10 amp gel cell also acts as ballast.
Hey Mates,
This is my first attempt at stick building a boat. it's a DUMAS (model 1203) 33" 1:16 scale Coast Guard lifeboat. Am learning OTJ (on the job)....
The kit is approx 6-7 years old found it on EBAY for $77 USD. Nice wintertime project.
Happy Trails.....
BRAVO ZULU! WELL DONE. The USCG 44' Motor Lifeboat was my first RC endeavor as well, in 1989. My latest is a Barracuda RC Boats 1:12 USCG 52' Type F Wooden Motor Lifeboat. Can't wait for 2018 navigation season!
HAVE A SAFE RC BOATING DAY
FAIR WINDS & FOLLOWING SEAS
GOD BLESS AMERICA!
Built from kit . it has full lighting and smoke from the shrimp boiler (the lid is off my wife's coat )and working trawler nets ,( causes a right drag when deployed)
Aerokit Sea Queen I built this about 10yrs ago sold it by chance it made its way back to me this year in a sorry state so it has been given a full overhaul and runs like a dream
Thanks Sandy it is seriously fast two 1400kv motors running on 4c 5000mah lipos 90a watercooled esc I have just sold it as I am nearly finished building another Perkasa with the same running gear the deck fittings & armaments are from Battlecraft I will post some pictures soon regards Bob
