Hi Roy, Like I already said in similar threads; pay a bit more for major producers, like Panasonic as you mentioned, and you are more likely to get what you paid for. No names are always a gamble. May be a super start-up, may be a 'let's cash in band wagon jumper! Whoever the 'supplier' is a relatively small number of manufactures are behind them. Yer pays yer money and yer takes yer choice! Personally, for the bigger, more expensive anyway, drive batteries I go for a supplier with reputation and known sources and reliable recourse without questions if you are not satisfied. For the little, cheaper, accus. for my Plastic Magic and auxiliary functions I am more inclined to experiment, log the results (manually!) and adjust future purchases accordingly. Regarding your super duper data logger; how has really it helped you? I used them often in my professional life, mostly as chief of the Rank Telecomm personal radio test department in the 70s and 80s, but now I don't need to sit in front of the PC analysing such data for hours. Time I could better spend building, sailing or solving other more interesting problems. Without appropriate analysis algorithms data loggers are useless. I have a thermocouple add-on for my multimeter which tells me if a particular cell is overheating compared to the rest. (The finger tip test usually agrees with the thermocouple!) This gives me a more useful indication than lots of abstruse graphs which you then have to interpret correctly. The money this cost you might have been better invested in a better charger as Dave M has already advised. I repeat what I said in the thread Dave mentioned: if I note that an accu. has a weak cell I degrade it to non-essential functions, nothing needed to bring the boat home! Each to his own; if you want to spend your time pondering over dubious statistics carry on and good luck! Personally I think Life's too short to waste on such things! If it woiks, don't fix it. If it don't woik fix or replace it, but don't waste time on bait digging when you could be fishing! Forgive me if I'm insulting your intelligence, for all I know you may also have 40 years professional experience in electronics. Let go! Cheers Doug 😎
[Score: 5/10] 72" Experimemtal Capable of 11mph and a runtime of 120mins Powered by Lead Acid (12v) 7Amp/h Batteries - Comments: Ebay Purchase. Originally a test tank model. Pumped water ballast no rudder or keel. Now fitted with lead fin ballast plus 2 7ah gel cells. and auxiliary motor. Sailing rig "A" class . 72in long 32 in beam .Hull strip wood deck fibre board. Sail winch and heavy duty rudder servo fitted. Design guess work !! Note picture of setting up rudder. 3 years work.
Continuing on - Grease up the prop shaft. Finalise the rigging. Another Radio check, with auxiliary motor, then disaster, Lost the hatch top, searched for 1 and 1/2 hours, no where to be found, Out came the saw and we has another cutting session and added some veneer, all was well.
Purchased on well known auction site. Boat very dusty/dirty but sound. It is from a Robbe kit that was around about 10 years ago and has timber decking, built-in auxiliary motor, navigation lights, etc. A deep clean followed by a re-paint of the superstructure, rub the decking down and varnish, followed by a complete rub down and re-paint of the hull brought her back to a fine yacht. She is about 40 inches in length and sails beautifully and has great presence on the water.

It was owned by an old gent who had passed away and was covered in dust and the ABS white hull had yellowed with age. I cleaned the yacht up, rubbed the timber decks down and varnished them, re-painted the superstructure, rubbed down the hull and spayed the hull a grey/brown colour. It came complete with auxiliary motor, batteries, sail winch servo, ESC and navigation light switching unit. The yacht sails perfectly and looks great on the water. A real bargain buy.
I like Douglas Adams books. ..(and Terry Pratchett too) But I was most attracted to Gusty Cat ... So.. Model of thames barge , build according to modified plans of sb Lady Daphne in scale 1:28 (length cca 1 meter ). it will be again a model with an auxiliary motor, staysail class. I am currently grinding the laminate hull with several layers of putty. It is an ungrateful job.
I spent 2 hours of solid surfing and found one other picture (which was of lousy quality and therefore no use). I hate to be beaten by things like this. One limiting factor is that the Independence class ships are all being replaced with new Literal variety of ships. RSS Independence has already been replaced by a new RSS Independence Literal class of ship. Sorry I couldn't be of more help. I have sent a mail to a friend of mine who lives in Singapore and is a Royal Fleet Auxiliary officer, to ask if he can find any info. I'll let you know when I hear from him. Again, apologies, Dave W

Hi Hammer Your build looks as if going to be really interesting, Are you building it from Scratch? Will it be RC or will it be Static display? If RC will you be putting an auxiliary motor as in the real one.
