I am using 1 12v lead acid battery in my sea queen with a brushless motor. It’s only giving me about 15 minutes on the water. The boat will get up and go for a few minutes but after that I can have the throttle wide open but the speed has gone. Can I link more than 1 battery together to give me a greater voltage which I believe a brushless motor can cope with. If so which batteries should I use and should I wire in series or parallel? I await your thoughts Thanks
I need to get a lot of weight into my Clyde puffer (approx 15ILBS) I have used a couple of old 12v lead batteries either side in the middle,have got a fair bit of room to play with at Bow end. Access to the stern is very limited and I need to get about 4ILBS in there as the prop is half out of the water. Any suggestions out there.
I have the Sea Queen which has a Jp C50-20 brushless motor. I use a 12v lead acid battery as power supply. The battery powers the motor and the steering servo. My issue is that when fully charged the boat gets up goes very well,however after about 10 mins I can have the throttle stick wide open and it's hardly moving. When I use my % tester on the battery afterwards it tells me I have 60% left. If that's the case way won't it go. Seems a false economy to charge a battery for hours for so little run time. Should I change to a different power supply or am I doing something wrong.
Can anyone tell me the best way to secure a fabric flag to a brass pole. Do I use fabric glue and wrap around pole,or just glue to one side of it. Or attach some thread to fabric and glue that to pole. Thanks in anticipation. 😊
I am building a Sea Queen,I have painted It with Halfords rattle cans and have got a really good finish on It as I used their leveller on It when It was touch dry. Question Is,should I add a clear coat or not. Somebody told me that I could use Sugarsoap Instead of a fine wet and dry to take the shine off. Any advice out there?
I have a Joysway Focus In bits. The problem I have Is that I do not know how to connect the two sails to the winch servo. I have done a little bit of research,pulleys and the loop system has come up a lot but I can't find any diagrams to put me on the right track. Can anyone help.
Can anyone help me the Winch servo on the Joysway Focus. I have got a Focus hull with Rudder and sail servo fitted. What I do not have Is any Instructions as to how to connect the two sails to the Winch servo. I have had a look on line and pulleys are mentioned and continuous loop. Can anyone help.
Thanks Chris, Boat Is still In build stage with a lot still to do,I can't see It being finished this year as I only do a bit to It when I have enough spare time. We are In the Dorchester area so may come down to Mangerton mill on 24th to have a look. Regards Richard
Thanks for your response,The brushless motor I have gone for Is a JP C50-20. I can not water cool It as the outer casing of the motor spins when used. I only got It last week so that I could get the mount and prop shaft lined up. I still have a lot of the build to go(not got the decks on yet). My local model shop would sell me a esc with a 65amp rating,someone else has told me to go 25amps over motor rating. I would of thought that If you have a 85amp motor you go for a 85amp esc. I have not thought too much about batteries yet,but looking likely to be lipo. Told that the 3 bladed brass prop that came with kit Is ok to use. Regards Richard
I am building the Sea Queen and have fitted a jp c50-20 brushless motor. Which speed controller should I use. The motor Is 85amp yet I have been advised to use a hawk controller rated at 65amp. Jp sell one which Is rated at 85amp which makes since to me,why would I want a lower rated one to the motor. Any advice welcomed.
I have just started putting the hull skins on the Sea Queen. I have tried to do It without using too many pins. Do I take the pins out and fill the holes after or do I use a punch to get the pins In low then put a scrape of filler over the top.
Just fitted stringers to my Sea Queen. Do I have to sand the stringers from bulkhead 1 to 6 to shape so that the skins sit flush on the stringers or do they over lap and the side skins come down to meet them and then are trimmed. This Is my first go at this and don't want to mess It up. If any one can help or has pics as to how the bottom skins sit I would be grateful .
