    ๐Ÿ“ Lipo battery charger
    10 days ago by drspock ( Petty Officer 2nd Class)
    Flag
    Thanks for the tips JB.
    I do believe it is genuine.
    I have seen the copies available.Even the genuine ones have
    variants,including different balance ports,which can catch out anyone.
    The genuine ones do have a hologram.

    ๐Ÿ“ Lipo battery charger
    13 days ago by drspock ( Petty Officer 2nd Class)
    Flag
    Continuing the saga:
    The charger has a battery test facility.
    This shows a) total voltage 3.7V rather than the 11.1 to be expected.
    This seems to explain the "no battery" message,because the charger is looking for the 11.1v to be expected from 3S.
    However when the battery is metered,it shows 11.1V. This
    suggests to me that the charger is not detecting two of the cells.I can only now get a new charger and hope I am correct!
    Thanks for all replies.

    Thank JB,
    All settings correct.
    Tried different charge modes.
    Metered battery right up to banana plugs,also across each cell on balance lead. ????????! If I do not connect balance lead,it says
    "connection error".Connect balance lead " no battery".Just don't
    Know.charger is powered on AC lead,230V.

    Hi Rick,
    The case is that the battery is more expensive than the charger!

    Hello Chaps.
    Ihave a Imax B6 V2 lipo charger.It has been used about four times over two years or so to maintain charge on a Turnigy 4S battery.
    The last time I used it,it indicated a faulty battery;upon inspection,one cell was completely "puffed".
    I now have an Overlander 3S battery that today I tried to charge (It is new and unused).The charger says " no battery".when starting to charge.
    I have metered the main battery leads,and get 11.3V.
    I have metered across each balance terminal and get 3.7V on each
    cell.So,battery looks OK. How likely is it that the charger is faulty
    or was damaged by the faulty Turnigy battery.I am in unknown territory here,so would really appreciate any advice.

    Hello chaps,
    Although not in imminent ( is that correctly spelt?).need,I would like a decent flag/flags on my crash tender.
    I have bought becc flag before,and found it stiff,flimsy,and generally unrealistic.I paid too much from an Australian supplier which was also pretty poor.
    Can anyone recommend a good supplier (in this case an RAF flag)

    Hi Graham,
    Referring to your reply on the latching relay,mine has arrived from China after nearly three months!
    My question is;what connectors did you use on the pins?
    Thanks in anticipation.

    Sounds better than grain filler for protective purposes.

    I am building a large wooden kit from Vintage model works.
    Even though the ply is very good quality,even after two coats of a thick etch primer (my little foible|). there was a deep grain showing through.I could have applied innumerable coats of paint,with rubbing down between each coat,but I thought this is not a new problem,there must be a better way.
    I tried Rustins grain filler.Applied with a brush, squeegeed into surface,left overnight.Next day sanded with 400 wet and dry.Wow!
    Perfect!
    Just sayin!

    Hello chaps. I originally searched for this subject under RC and electrics and was surprised no one had already raised it.
    I am running a Tornado thumper 4260/06 500KV in my 46" crash tender,with a 90A Seaking ESC,and 55mm 2 blade prop.
    The maker suggests a 3S to 7S Lipo battery.Does 7S even exist?
    Question is, taking cost into consideration,what "s" voltage is appropriate? I will be switching 12V LED lights as well.Would 4S @
    14.8V damage these? Grateful for any advice!

    Is what the name suggests,very flexible strip wood that needs no further treatment to bend it. Good luck.

    In respect of the Vintage model works 46" Crash tender,I am struggling to find 1/12 th scale crane pulleys;there are loads of small stuff about,but I cannot find anything of a realistic size.The crane (davit) hook is a big problem.Any steer would be valued.

    I am building the Vintage Model Works 46" crash tender,and with the aid of Robbobs build log,it is going pretty well.
    I successfully steamed the gunwhale and chine stringers.However,the rubbing strakes would not have it!
    I have seen a passing mention on this site of flexible beech,and looked at a couple of suppliers;the price is a bit frightening compared to obeche strip, but I ordered some.
    What a revelation! It is ridiculously bendable! Job done.
    I am reluctant to advertise anyone who has cost me money,but have to give others the chance to avoid hours of unnecessary grief!There are two suppliers,and both are low on stock at the moment,but Cornwall model boats are very reasonable with postage,which makes the price more palatable!
