    (Pleasure Craft) "Jessica" A Sea Scout renovation
    Originally built by my Dad in the early sixties, fitted then with a Taycol Target and two very wet lead acid accumulators. First renovation about 26 years ago for my daughter Jessica, fitted with a 6V Decaperm. Performance was VERY sedate. Perhaps fitting for a Broads Cruiser? The Taycol will now go into the Danish fish cutter I am currently renovating. First two pics show her condition, incl. engine room, last year after about 25 years in the cellar. Last three pictures show current condition after extensive renovation, see 'Build Blog Jessica' and refit. Video shows her Sea Trial end of May 2018 https://youtu.be/b0BWJ3duzDw Now just cockpit fit to do and suitable crew to find. Can't 'select' Speed here as she wasn't equipped with GPS! But quick! Now she planes well so I guess I've turned her into a Sport Fishing Boat!? Rating I also can't select for myself, that's something for you guys to do! ;-) (Motor: Propdrive 2830 1000kV) (ESC: Quicrun 16BL30 Hobbywing) (5/10) Update: Crew have reported for duty๐Ÿ˜‰
    (Naval Ship) HMS Belfast
    Performance not yet known, still in the fitting out dock. Power is actually 2 x 6V 4Ah. ESC will be Graupner Navy V30R. Maybe 2 for differential control to support rudder. I've left 'Number of Props' as Please Select cos Belfast has 4 and this ain't an option!! Long term plans for smoke (borrowed from model railway kit!) lighting and gun control. Have already bought magicians 'Flash Paper' for main battery gun flashes. Ignition using old 'out of work' glow-plugs? Any ideas welcome :-) Ship is Graupner Premium line. NOT IMPRESSED with quality of cast resin parts, lots of air bubble depressions :-/ Fair amount of rework / repaint necessary! (Motor: Speed 540 x 4) (ESC: Navy VR30 or Viper Marine. Trials on 40MHz then 2.4GHz DX6) (7/10)
    (Naval Ship) Graf Spee
    It's a Graupner premium line ATR! ;-/ Wanted some 'quick fun' while working on more complex constructions (HMS Hotspur H Class Destroyer 1936, 1:72 and Type IA U26 also 1936). Didn't work out that way! On first test of motors and ESC I discovered that the shafts were so badly fitted that they were binding ;-( So back in dry dock for some hull surgery! That's why some inputs are missing above. Plan is to gradually add functions and special effects; lighting, gun controls, magicians Flash Paper for gun flashes. Maybe fired using my old glow-plugs!!?? Now I'm freshly retired I have more time for this ;-), as long as Gisela doesn't drag me off around the world too often ;-) I also have HMS Belfast from the same series (approx 1:128) also awaiting fitting out. More soon - don't hold your breath please ;-) in the pipeline is some 'Plastic Magic' with Ark Royal, Hood and Bismark all to 350 scale ca 70-80cm. Sorry been in Munich for over 30 years don't think in inches any more (except when buying mag wheels for the chariot!) Cheers, and as my German boating friends say 'Immer ein Handbreite Wasser unterm Kiel!) = I wish you always a hand-widths water under your keel. I sail on the lake in the Ostpark near me in Munich. Very convenient, right next to the Biergarten! ๐Ÿ˜Ž (Motor: 600) (ESC: Graupner Navy V30R) (5/10)

    "working a new one atm of a pt 109 boat, powerd by a jet motor like the origional design."
    Sorry Staffros, but I think you've got your wires crossed somewhere๐Ÿค”
    The PT Boats were never fitted with water jets.
    As far as I know water jets hadn't even been developed in the 1940s.
    PTBs were driven by 3 conventional shafts and screws powered by Packard engines.
    You may be thinking of the PBR (Patrol Boat River) as used in Vietnam.
    Otherwise known as Pibber.
    As I am restoring an old wooden PTB, and rebuilding as PT109, I have done considerable research on the PTBs. Mainly ELCOs like 109.
    Here's a couple of basic links to illustrate what I mean.
    PT Boat
    https://en.wikipedia.org/wiki/Patrol_torpedo_boat_PT-109
    PBR
    https://en.wikipedia.org/wiki/Patrol_Boat,_River

    There are plans and kits for the PBR on the market, and some examples of models here on this site.

    ๐Ÿ“ Brushless Motor problem
    13 days ago by RNinMunich ( Fleet Admiral)
    Flag
    "I assume the two x 10 Cell NiMh Batteries would be connected in Parallel not in series. Otherwise the voltage would be too high. Do you agree?"
    ABSOLUTELY NOT CHRIS!
    Connecting batteries in parallel can be dangerous, unless both have identical characteristics and charge states. Which is seldom the case! Danger is if that if one battery is at a significantly lower state of charge (voltage/capacity) then the other will try to charge it, which can cause very high current to flow --> FIRE๐Ÿ”ฅ๐Ÿ˜ญ So called Back Charging.
    The way to prevent that is to connect the two batteries via fast Schottky diodes to prevent the reverse current flow. Connecting two 12V NiMh (10 cell) in parallel still only gives you 12V supply for the ESC and motor.

    BUT, you NEED the high voltage to make the ESC and motor you are using work properly.
    Connect the two batteries in series; i.e. + of one to the - of the other. Giving a nominal 24V using 10 cells or 19.2V NOM for the using 8 cell batteries. If you're worried go for 8 cells.
    Should still give you decent performance
    Make sure that the two batts are from the same manufacturer and of the same capacity (mAH).
    When you get the new batts put them through 2 or 3 discharge / charge cycles to condition them for their new life ๐Ÿ˜‰ That will help to get them both to the same charge state and prolong their useful life.
    If you don't already have one I recommend that you get a voltage / capacity checker. Available all over Amazon/Ebay for a few quid.
    Happy Batting๐Ÿ˜‰

    Hi Jacko,
    " wheels needs to be printed photos as and when "
    Why not have a trawl round the RC car/truck sites?
    I'm sure you can find some suitable wheels (and drive train parts) there.
    Or with your skills, why not 3D print some rims?
    Then buy some RC truck tyres, to give better traction than the hard 3D print plastic.

    Hi Chris,
    I kinda figured that ballast came into the SLA equation there ๐Ÿ‘
    I do that with my larger warships (ca 1.5m) as well.
    I too prefer 'power ballast' to 'dead lead' if possible.

    Reckon you'll be pushed to find NiCads nowadays.
    They're rather environmentally infradig these days due to the cadmium.
    I'd go for two (8 or 10cell) NiMh of the highest capacity that fit the budget.
    That should provide decent ballast and decent performance/endurance.
    You could also consider fitting one either side of the hull to help with roll stability in turns.
    Just a few thunks๐Ÿ˜‰. Happy sea trials๐Ÿคž

    Hi Terry,
    I note from the SLEC website that they recommend a Brushless Motor : 3536/8 1000Kv.

    "Parts Needed to Complete the Model
    10in x 4mm Prop Shaft PR830B
    4mm to 5mm Coupling PR840C
    Small Rudder PR833A
    2 Bladed Prop 40 with 4mm thread PR 834A
    Brushless Motor : 3536/8 1000Kv
    50amp Brushless ESC with Reverse
    3s Li-Po Battery Pack
    White Metal Fittings Pack Available Part No PR804A"

    Considering the size of the boat (25.75") and the motor diameter (36mm) I would be more inclined to fit a 35mm prop. I'd use a 3-blader but that's a matter of taste / aesthetics ๐Ÿ˜‰

    For reference, my 24.5" Sea Scout gets on the plane and runs very nicely with a 2830 1000kv brushless, 30mm 3 blade brass prop, running on a 3S (11.1V NOM) battery.
    See my trials results here

    Hi Rowen, Graham, Chris,
    All very valid points, but -
    I started with an even simpler thing - looking up the Specs of the components and Battery voltage required! (My test engineer instincts coming through ๐Ÿ˜‰)

    I believe that 12V is not enough for this ESC / Motor combo.
    I found the same manual as Graham and checked the ESC specs, see page 1.
    Esp. Operating voltage and Battery type (relevant for Cut off voltage!)
    The ESC expects a minimum of
    14 NiCad / NMIH cells, =16.8V NOM
    or 4 LiPo cells. = 14.8V NOM.
    So I strongly suspect that it detects a 12V SLA as a deep discharged battery and goes into Cut Off mode, i.e. shut down, with beep beep beep ... alarm.
    Unfortunately the ESC manual does not specify the default values.
    These may well be in the Programming Card manual though.
    Strongly recommend that you buy the programmer Chris, much easier and quicker than 'beeping around'.

    The motor spec also specifies higher voltage;-
    https://www.cornwallmodelboats.co.uk/acatalog/P4445810.html
    "Energ Brushless motor, suitable for large model boats such as Sea Queen
    Battery - 5-6 cell Li-Poly, 20 Cell Nimh (18.5V / 22.2V NOM Lipo, 24V NOM NiMH)
    Weight - 300g
    670Kv
    Connectors - Gold included
    Working current - 40-80A : Peak 85A
    Shaft diameter - 6mm
    Speed Controller requirement - 85A."

    So Chris;
    Either get another 12V SLA and put the two in series or (and much better cos the ESC won't recognise the two SLAs and may 'think' they are a 20 cell NMIH) get yourself a 5 or 6 cell LiPo.
    That will be much lighter and have a much better power to weight ratio than the SLA.
    SLAs are generally not happy delivering high currents.
    They were developed essentially for long term back up low current supplies.

    Hope this helps.
    Cheers, Doug ๐Ÿ˜Ž

    "You will also note there are no instructions shown.Silly Billy lost them,or rather put them somewhere safe a long time ago and now because of many and increasing senior moments canโ€™t find them!"
    Know the feeling Bill๐Ÿค”
    Had to grovel around the internet to find some instructions for my 1/350 Merit Ark Royal (1939). Had gone nuts tearing up the flat looking for them.

    These any good to you?
    See attached pdf.
    It's a slightly later version but the basics should be the same, just retooled I think.
    Your version, 05061, doesn't seem to be available on Revell's Download site.
    If not I can scan the instructions for my earlier version (05007) bought over 30 years ago here in Munich. First generation Revell version?
    I had just seen it advertised as NEW in ModellWerft (Model Shipyard), kinda German Model Boats, and thought she'd be a great partner for my 1/72 destroyer. I'll get to building her one day๐Ÿ™„
    Cheers, Doug ๐Ÿ˜Ž

    Trying to find a South American channel were you Rick?
    I was wondering if tube is correct for the TV antenna.
    On the plan it looks more flat to me?

    Glad you like the Eze-Kote Rick.
    I swear by it - especially when I spill it ๐Ÿค”๐Ÿ˜
    SFSG on the construction๐Ÿ‘

    BTW; Can it be that your shaft toob is a tad close to the rudder?
    Gonna need a real slimline prop!

    Hi Stephen,
    "Yeah who would have known I would get to being a fish head.๐Ÿ˜
    I guess that's better than being a 'Cod Piece' ๐Ÿ˜ฎ
    I wish you more steam to your drifter (might stop her drifting ๐Ÿ˜).
    Watching (and learning) with enormous interest๐Ÿ‘
    'Fair dinkum cobber!'
