I want £250.00 for her, it cost nearly £400.00 to complete and no I have not sailed her on the sea as it is nearly always too rough on the south coast. I am also an O.A.P. and need the funds, thank you Brian.
Hi there thanks for the interest in the San Diego. She is actually just white and blue. Her dimensions are 52" (1320mm) long, 9.25" (235mm) width and 15" (385mm) high. Hope this helps. away now will answer on Monday any more enquiries, thanks Brian.
Thank you, yep put it on the water and another ESC packed up! Replace the ESC and it went very well but need adjustment of the batteries. Now it goes on the plane at a very scale speed. No need to go to fast as it is a working boat after all. Will try and get a video but it has gone home now so I will ask the owner to get one.
Maiden voyage of American Enterprise on Poole Park Lake 10/2/15. Leopard 4074-1400kv x 2 Mystery 100a ESC x2 all watercooled. 4 cell lipo 6500MA. Went very well until one brand new ESC packed up! Second one to do this, bit iffy I reckon. Turns a treat and very scale like in running.
Thank you Derek for that info I did look at the Turnigy motors having had them in aircraft and them being reliable. That sounds about right combo doubled up would make it go. My Riva has outrunners with a cooling mount on each and cooled ESC's. The inrunners with jackets look good but way over power I think, to high a Kv making them more suitable for racing machines. Thanks once again, brian
HI there, new project: Robbe San Diego super yacht. I want to put twin brushless in her, has anyone done this on this forum? If so would they be kind enough to assist me in letting me know their set up and performance. Or, could anyone advice me. I am thinking 500 watts per motor similar to my Riva. The boat is going to weigh about 5kg. Its 1250mm long by 250mm wide. Thank you in anticipation, Brian
First trip out 100Mtrs coupling broke, calmest day for weeks took an hour to get back!! Built from plans supplied by Colin Smith. 38/32 brushless motor, 125A ESC, 4 cell lipo. When It went It went! Motor, ESC and motor mount water cooled. I will get a new coupling and try to get a video of this hope we have some more calm days.
Thank you for letting me know the result, It Is all a great experimentation, but helps If you get of to a good start. I'm pleased that you are satisfied, but It might be worth different props. Have you a watt meter that will read In the boat and save results so you can see what power Is being consumed for best performance? Placing In water and holding on Is a good way but not perfect. I trust the water system Is running OK as well, Brian.
HI thanks for your Interest, Yes I used brushless outrunners on an aluminium mount. I used Hobby King water cooled ESC's using two separate Inlets with two seperate outlets. The ESC's have four nipples so the water run Is thus: In through the scoop on one side of the boat onto one side of the ESC and out through the other side to the second ESC then out of this ESC to the scale outlet on the boat; repeat this on the other scoop and the other side of the ESC to the other outlet. I put the ESC's close together In the centre of the boat, this way If one side block the other will hopefully still work to keep the ESC's cool. The motors get get warm but not hot the ESC's remain cold. I have run this set up for up to 15mins with no problems, Poole Lake Is a brine so It Is Important to flush every time I have put a T junction In both sides and use that with a syringe. orry to be a bit long winded , If you can't understand my dribble contact me and I will try a drawing or photo, Brian
HI there, I got my hardware from www.gianhien.net, they have several models In different scales look at my build blog for my 1/7 scale Riva on this site and you will get some Idea of what you get, 21 day delivery from receipt of money sent Western Union. Quality good but not excelent, as long as you keep It waxed It will last. Hope this helps, Brian
