    Peter,
    If you measure the dinghy and then the gap between the crane jib(taking into account the supplied hook) according to the plans it is touch and go if the hook connects directly to the middle bench and not as per the building instructions(which use carrying chains.If you do not shorten the tubing (BK12 on the plans) it might work but looks wrong. the other alternative is to shorten the side rail by 2 uprights and use a chain but you may have a problem with the mooring bollard.
    This seems strange me offering advice rather than asking for help!!!!!

    After nearly a year and with a little help, advice and guidance from members (I tell lies it should be a lot of help) with special thanks to Martin I HAVE FINALLY GOT MY DUSSELDORF WORKING!
    I could not get the switch module working (and still do not understand how it works) decided to set a reduced operation, and only use the GR-16, 8 channel receiver.( the manual says I can run two receivers and when I tried it all that happened was the operations were duplicated.
    What I have done is to ignore the anchor winch (Water is too deep in my pool and tiled floor), the hoist and winch at the stern as the dinghy is too big to go over the side rail and the raising/ lowering of the monitors
    The lighting (except the blue light) and radar motor are wired together and manually switched on before the boat leaves.
    So far this leave me an unused receiver!
    I programmed the boat pre-set on my transmitter which automatically gave me steering and speed controls on the right joystick and training of the monitors on the left joystick( the two cabin monitors on horizontal direction and the bow monitor on the vertical).
    Some of the wiring had only two wires to the receiver so would not work, this was overcome as follows: the blue light had a blinker switch. I used uno switches to operate the searchlight motor and the pump( I was going to use three Krick uno switches) but after couple of weeks found the receiver would only operate two!
    So I have finished up only using 7 channels!
    I intend to now tidy it up and see how it operates in my pool hope to video some results and post later!
    THANKS for all the help given to me and watch out for Graupner problems (Manual in excess of 100 pages not counting the receiver)

    When I retired went to Spanish lessons and said to the profesora
    "Tengo un rollo de papel higiΓ©nico que enumero mi trabajo. cuando termino un trabajo, arranco esa pieza. Por cada uno eliminado, mi esposa agrega dos mΓ‘s.
    In English, I have a toilet roll which I list my work. when I complete a job I tear off that piece. For every one removed my wife adds two more!

    Martin, followed your advice, I have connected the two receivers (tried binding together,individually and from different power sources) only to find they duplicate each other every time, so have 8 channels(plus 8 duplicates). all channels I tried switches will work if using a servo but apart from the blue light (which has a blinker unit) all others are on permanentely (the switches,even set on transmitter) do not work.
    have 3 channels available to run3 motors
    radar(on permanentely),searchlight and water pump(as necessary),also 2 sets of lights(if all lights are on together and search light as necessary).
    could connect lights to radar motor to save one switch which makes one short.
    Cannot have all monitors together as two on cabin are facing aft and one on bow faces forward( might try reversing bow monitor servo)

    I may have a faulty switch module and just accidently found out the Robbe switch module is conpatible to the Graupner hott systems!!!I am therefore getting one, changing the wiring as per the original wiring diagram and hopefully getting further on( may even complete) and get things working as it should!

    I am back again! still having problems!
    I have been able to connect the blue flashing light and allocate it to a switch via a Krick Ro8220 binker unit!!!!
    I then wired the running lights together and tried to allocate a switch so I could turn them on and off at will, the allocation was successful (tried the flashing light which works) but will not turn the running lights off or on, tried them on the channel and switch for flashing lights but still wont work( they work if I connect them directly to a battery).
    Have tried every combination of 2 & 3 wires without success! any ideas?????

    sorting out and checking wiring, so far so good! put boat in water today to check for leaks( and basic driving and turning) pool 8M*4M, not big enough as boat goes "mas rapido". found I had 12mm water in hull, fortunately not affecting electrics, My own silly fault, did not make sure water inlet pipe for pump was above water level! now letting it dry out but thinks that is the only water ingress!
    next stage RADIO SETTINGS but will do 1 at a time, Garage now warm enough to work in without gloves.

    have been moving forward slowly from restarting from scratch, reading manuals and have changed the speech on transmitter to english( the controls have been changed some time ago).It is saying " receiver voltage" on the transmitter it is showing 2.7v, I have then checked the voltage going into the receiver (trying several cables and even plugged power supply directly avoiding the switch)and is 6.5v so is it a faulty receiver or the transmitter?

    Mouldbuilder,
    How did you get on with the programming, I am still having difficulties and being helped by G6SW( see Graupner Mc-26 on Forum)
    If your system worked OK, did you make a wiring diagram? as I nearly ditched my transmitter so may try your system!

    Just heard I can get my cable from my postbox Monday so will be able to sort the wiring, trying to work out wiring plan (see photo), what do you think?
    In case I get fed up have ordered a Tamiya Konghead 6x6 car kit from cornwall so I can relax a bit, have plenty of areas to play with it( due wednesday)!

    Jonathan,
    regarding previous entry about graupner 3970,emailed Krick and just received a reply"With the module from Graunper you can switch a consumer on and off. The module is connected directly to the receiver and is not available. An alternative from us would be the Uno switch article number 67201 from us."
    looked at comparision and found" the 8249 is designed to be used with the robbe/Futaba Multi switch"(see photos).am now wondering if I used wrong units (used them as recommended in build instructions and wiring plan)?
    Regarding brainwave started transmitter and very quickly wished I had not as could not find switch settings"NOT A HAPPY CHAPPIE"😭😭😭😭
    Am wondering if I was to reduce the number of channels, by putting all lighting together and removing the servos for the vertical movements of the monitors, would it make it easier? but it still means setting the transmitter up!
    Because of the hassle, I am seriously considering having a break from the Dusseldorf and making another model before having another go

    I have been checking and cofimed all wiring is correct and no sign or smell of cooking except for the common earth, which have to sort). unable to upgrade wire to swg22 as our village is in lockdown,we can go anywhere in arboleas but not to ALBOX 7km(where my mail is delivered) away as is outside provence unless I try to play hide and seek with the guarda! I have found 1 servo,pump as well as the 8249 reversing module no longer work and will have to replace!
    question, is the graupner3970 Switching module multi-function SXH the same as the ro8249reversing module f. multiswitch? if so might go that way and decide and order the next model i want to cut down delivery charges
    Might have had a brain wave regarding switches after reading notes several times, could it be that you select the channel the drag it down to the apropriate switch and "set"it?

    have been checking the wiring and replacing some(found by chance the wires I got were SWG-26 and have ordered some SWG-22 (think it is better and withstand higher power) so will replace some wires when it arrives.
    have checked the circuits, both before and after the block connecter and apart from 1 Servo all OK.
    Now to set up receiver to switch module patch cable OK, 3 polarity inversion cables made up and checked(will upgrade when new wire arrives),so have to sort power supplies and where their wires go? then back to setting up the mc-26!

    Charged up batteries yesterday for an hour, and again this morning whilst making up test cables cut the common earth wire thus removing all wires and plugs to the switch module except the patch cable and am replugging the receiver checking each one before and after(using channels 1 and 2 which are pre-set on boat setup) to check my wiring so when it gets to the muti channel module any errors have to be in the programming .
    Incidentally before the above, I plugged in the new( rewired with the matching cables)"polarity inversion modules" and tested them all seems ok,Stopped to see F1, brought back some memories(both good and bad) when the car brewed up, fortunately driver got away with it, not a good sight if they dont!
    slowly progressing!

    Not sure I understand your wiring diagrams?
    Page 7 of 3972 Manual (Ihave a later version which shows different dimensions and weight but comments are the same) it says" through the suitable cabling of connection cable the functions can be powered by a single power source (I assume this is the feed from the receiver) or separately by different power sources". This intimates the 5 motors and the pump should have there own individual power supply, rather than my initial impression of page 11 "connection of a big function to channel 4A and the common earth" with a light for each ( I thought they were isolation switches),thoughts please ?
    Switched on the transmitter and the wired up receiver(Power and patch cable only) and got no light on the receiver so am now charging up the batteries so will remove the common earth wire and start again tomorrow AM. F1 race at 3pm tomorrow (spanish time)

    Jonathan and Tora Dog,
    I agree with Jonathan down to the multimeter and yes I do have one:
    I understand about the 3972( I think that is the reason for the polarity inversion modules for use with the 8249 transistor pole reversing modules) your wiring sketch is very similar to the "connection of a big function to channel 4" except that they recommend a common earth, page 11 and it shows power in on X1-4c and negative X1-4A which I have done but not yet plugged in.
    Tora Dog,
    Thank you for your input it is appreciated and "many hands make light work"I was originally concerned about the 2 banks of sockets on the Graupner and was advised that the Robbe multiswitch 8369 was a two way switch and the Graupner 3972 uses a single switch with a common earth hence the second bank and the polarity inversion modules

    Jonathan,
    got cable and plugs yesterday and have made up 3 polarity inversion modules and plugged them into the switch module (no power connected yet). this morning made up the 2 "connection of big function to channel 4" and plugged it into the switch module.
    looking at it it seems the power in(x1-4c) is the same bank as the return on the inversion modules. Is this correct???
    If yes I have found my previous big function plug was wired incorrectly(had power in on X1-4B) possible cause of cooking the 8249
