    Based on your clarification i decided to keep the Lead Battery 6Volt for the motor. also because i need the load to keep the boat balance. Thanks Ron and Tica.

    Robert maybe first i need to understand if use a 6V lead battery pack or utilize Lipo 3S or 4S. After that i need to define how to proceed. My idea is always to reduce the park of battery, more i have more job is request for maintenance. Is not a problem of money the topic is that the boat will be use anyway not so offend and i do not like to keep a Lead 6V battery in stand by for long time. If you think is possible for me is much better utilize 3S or 4S Lipo but i need the tension reducer that need to be install before ESC in this case between exit of battery and entry of ESC.

    Sorry maybe i done confusion
    The original boat used a 6 volts. Later on i start to think that i can use the Lipo battery that i have for my gliders that are 4S with 3200 mA/h.
    But if i use this battery and i do not buy a new 6Volt Lead battery i can have problems with motor that works with 6V. Because 4S Lipo has 14.4 Volts. In this case i need a Tension reducer. But i need to put this reducer between the battery pack and the ESC in order to entry in ESC with 6Volts. Can i find a regulator? I can use also 3S Lipo that also i use for my airplanes. I can use 2 packs of 3S in serial in order to have always 11,1V but 2200x2 mA/H. But also in this case i need the tension regulator from 11,1V to 6V Base on it (if i use the Lipo 3S or 4S). Before my question was just to understand if i can use Leds of 12Volts with a battery of 6V as the original battery package, What about the light intensity? Thansk

    Carsten sorry
    come to my mind a new possible solution. Can i use for my motor Graupner 280 Speed not the regular 6V battery but a Lipo 7,2Volts? Because maybe is better the Lipo. To compensate the different in weight i can add inside some pieces of lead. What do you think? Or is better to stay with 6Volts Lead battery?

    Hillro, good morning, i need to ask the following
    I founded on Amazon a set of LED 3mm Dia at 12 Volts already with resistance inserted according the different colors.
    Question
    In order to avoid to utilize the 6V battery of the motor also for LED, in this case i avoid to see the LED blinking by the motor run, can i use an extra battery dedicated only for LED at 7,2 Volt? because the the LED has 12Volts? In different words can the LED of 12Vols work with 7,2 Volts? Thanks Fulvio

    Good Morning Hillro. My name is Fulvio and i write from Italy. After 20 years with RC airplanes now i would like to add a new hobby the RC Boat. Based on it i have a new project that is to renew an original ELKE HF408 Graupner. My wish is to add the lights on the model. I will utilize a 6 Volts lead-acid battery. I will use a Graupner Speed 280 brush motor. But the topic are the leds. I would like to switch on and off the lights by a regular servo (small one) that by the rotation of the arm can open and close the contact for the lights. I would like to make 2 lines, one leds line for the light on the boat (in order to give light on the bridge and inside cabin and the second leds line for the navigation lights. In this case i will use 2 servos. Now the topic is the follow: can you suggest some solutions? can you tell me some information's on the utilization of the leds? How to connect more leds tougher? Better to do a electrical split where to arrive with main power and then split different lines? Can i connect the leds after the battery and before the ESC? All the above questions is because i do not have absolute experience on the topic and also on the boats. Thanks for your support or the help of somebody else. If some body has pictures on the topic are welcome. Thanks Fulvio

    Caster good morning. My actual motor for the ELKE is a Graupner Speed 280.
    According the instructions the Max Ampere during the regular rotation will be 2,2 Amperes. In this case I would like to add a fuse on the wire + (red) but between the battery (lead-acid battery at 6v 4000mA/h) and the ESC correct?. How much need to be the fuse? 8 Amperes? 10 Amperes? Thanks

    Carster, thanks a lot fantastic you are simple the best. One more question how to check the right blade? because now there is one on assembled on shaft is a 3 plate blade but i do not know if is the correct one maybe i need to change but i do not know what to buy, The motor is the original one 280. I will utilize lead battery 6V. Can i Use Lipo at 7,2 Volts with original motor that run at 6 Volts? maybe for this reason better 6V battery. Moreover i have the ESC and it is ok but if i like to put lights that works at 3V how i can do to reduce the Volts in order to work with lights? One more question do i need a fuse on the line * between the battery and the ESC? Thansk

    Good morning to all of you my name is Fulvio and I write from Italy in order to ask if someone has the possibility to send me good pictures about the drawings of Elke boat by Graupner. I have an old model and I would like to revamping but I do not have drawings and instructions. I am glad if some one can support in in the new mission also because from 20 years I was involved just in RC airplanes and for this reason I prefer to have drawings, at least after I will ask some other support in order to set the Radio control in terms of ESC, lights on so on. Thanks
