Typical yorkshire weather, after 5 minutes it chucked it down so had to make a quick retreat. used just one 2200 3s lipo for now but need a bigger lake/pond really as can only give full power for 3-4 seconds, so stop -go is not good but was hoping to get some good photos-videos, but the rain stopped play till another day.
Edit, forgot to mention. most of run on centre prop only. the last 5 seconds or so is full power, well nearly.
Looks good Roger,
Whilst the comments on paralleling LI-POs are correct. I have never had an issue. I have used two identical cells and fully charge each separately until the charger cuts out.
Would never try two partially discharged cells as then the current might flow from one to the other creating the overcharge rate problem
Recently decided that rather than use two cells, why not use one at once? This reduces weight and eliminates the concern.
Think you need a larger pond! Glad to see the weather is consistent with my memorys.

MODEL BOAT SAILING - AT BUGSWORTH BASIN
Bugsworth Canal Basin, the head of navigation of the Peak Forest Canal, was the largest and busiest inland port on Britain’s narrow canal system and the only one to survive intact. Famous canal and tramway engineer, Benjamin Outram, built the 14 mile long Peak Forest Canal from Dukinfield to Bugsworth, although plans to extend to Chapel Milton via Whitehough were never realised. Construction of the six mile Peak Forest Tramway in 1795 linked Bugsworth Basin to the limestone and gritstone quarries in Derbyshire, and the canal linked Bugsworth to Manchester and the trans-Pennine canal network.
Its correct in every respect and its the correct texture too.
Every single part of the kit was drawn in 3D cad (123D Design) and produced on a Forms2 3D printer. Then everything was scaled down to 1/16th scale and thse are now available from Tony Bakewell, the new owner of Speedline Models. See facebook👍
You might have something there! I think his expression probably has more to do with the threaded rod glued into his nether regions which attaches him to the thwart! 😂🤣
I seem to remember warning you about that Graham 😮
Same for Ben and the smoke for his pipe I suspect 😮😭
Whatever, good to see at least Bill in action again 👍

That planked hull is a work of art, and can be appreciated for what it is and the work that went into it. Painting is for hiding mistakes and filler. Regards.
I like your boat a lot you have made a really good job of putting it together and it sails rather well also. But I am afraid that I must correct your comment if the fact it is a North Sea Drifter, and has never pulled a trawl net in its life to date. The nets were paid out over the side and could be a mile long in length, the net hung like a curtain with floats on the top, and the herring were caught by the gills and unable to escape. I also have the Mountfleet Danny Boy and will enclose a photo. Regards, Gary
I should have mentioned it has a gas-fired steam engine, and in order to obtain access the super-structure and the fish hold lifts off along with a large piece of the decking. Regards, Gary.
Lucky you built a strong boat Roger😁👍 She's running much better now and looks good. 100c will give you a truckload of power !! You can never have too much power👍😁
I've replaced the old 6v sealed wet battery with a lipo 3s,11.1 volt 2200mhz, 100c spectrum smart battery. so the 1st run was cautious i just fired up the centre prop to see how she performed, well i was surprised at the turn of speed she had on just 1 prop, and how well she planed, it was a little awkward filming and controlling the boat by myself as i was the only one pond side. this was not without mishaps though, see 2nd video
After checking the boat over she was found to be unmarked and no bits missing, not bad to say she hit the pontoon at full speed, took off and plunged back in at the other side.
So the second run i started on the centre prop and then opened her up on the outer 2, she shot forward and immediately stalled, dead in the water. luckily i could reach her with the ponds barge pole to pull her to the side. i found the fuse had blown , i had fitted a 20amp mini flat fuse, i didn't have a 30amp only another 20amp which blew just as quick, upon opening up the outer props.
any ideas anyone or will a 30amp do the job, or a 2s battery? help any suggestions considered.

Hi Ronan
Thanks for your input.
Its starting to make sense now.
I bit the bullitt and bought a lipo battery and charger. I ended with a spectrum smart 2200mhz,3s, 11.1v,100c.i had a choice of a 30c but thought it may not be man enough for 3 motors so looked at the 50c, but was out of stock, so i ended with the 100c it was the same price as the 50c anyway. The charger was a spectrum smart type to. This monitors the battery and hopefully does everything automatically.
Once again thanks for your help and encouragement
Roger
Hi Roger,
You are learning well! A similar road to the one I travelled a couple of years ago.
Hard to see the fuse block on my Brave now, but here is one am assembling for my next project. Got my fuse blocks off Banggood, they offer both 4 and 6 fuse ones.
Used a 6 on the Brave as wanted a fuse per motor, currently using 30 A capacity. Should protect the 50 A ESCs. Bigger fuses and even re-settable ones can be fitted into the block if warranted.
The home made buss bar and battery connector are visible.
Hope this helps.

100C should be more that adequate, mine is 30C. You should be able to drive a welder with it too!
