Well we wouldn't want that in reality Chris.AHHA i thought that would arouse you J/R :rolling: :tongue-out3::smiling2:an yes there is a possibilty
chrisb
Sure you will sort it out
boatman's 1/72 HMS Tiger C20 build
- Thread starter boatman
- Start date
Sure you will sort it out
HI Pete no i dont really like the idea of doin away with the fuses so i may keep these big fuses but i need a fuse box for thes big fuses do you know where i can find a big fuse holder ? or i may just solder the wires to the blades but not keen on that idea
chrisb
Would it be possible to use a fuse holder from a car!!
Maybe a trip to a local scrap yard with a selection of useful tools!! Hammer, jemmy, or something equally as destructive - but useful!!
No way would soldering fuses into the circuit!!:flushed:
Halfords, or any local car parts shop.

Do the larger fuses fit into standard 1/4" push-on connectors?

HI Doug well all the car scrap yards around here are all closed up as 90% of us car drivers have fairly new cars so the scrap yards have all closed im sad to say as i use to enjoy havin a look around the scrap yards for bits of my old car an no im not goin to solder the wires on as sent for a proper maxi big fuse holderWould it be possible to use a fuse holder from a car!!

So that will get fitted in the ship along side my normal fuse box so i will have the best of both worlds an i think i'll keep all these big fuses just in case i do need them as tiger is a very heavy model an movin her in the water must take a good bit of power an i may need to buy some bigger props but will see on that on sept warship day an cheers for your ideas
chrisb
OH HELL Pete im not thinkin this morn proberly got to much sun from on the beach yesterday but ive sent for a big fuse holder off ebay an paid a couple of quid more but never mind
AN YES Pete i thought of that an no the fuse blades are bigger as i was thinkin along them lines of usein them to make my own fuse holder which would have been easy but no shot down in flames again but ive just ordered one an my idea will be to leave in the normal fuse holder an fit the new big fuse holder along side it an then fit spade connecters so i can just unclip the wires from the normal fuse box an clip the main feed wire into the big fuse holder an have the same idea on the other side to feed power through a heavy duty
Y lead to both the 320 amp ESC 'S THEN TO ALL 4 MOTORS hows that ?
chrsb
I still think that the root of the problem is why the motors are drawing so much current. Are the propshafts turning freely Chris?
It must be getting pretty hot inside the hull. Do you have any way of recording the temperature? Maybe a greenhouse min/max thermometer? I sued to have a pile of little stick-on discs that change colour at a particular temperature, but they've all gone now. Something like these: https://uk.rs-online.com/web/p/temperature-sensitive-labels/7799779

HI Pete yes the prop shafts turn very easy so they not the probs an the big apetures in the hull sides have a back on but no top so the wind or air can blow through freely an there is a small fan nr the base of the second funnel that is running all the while suckin cool air into the hull an then a big 3 inch fan that i can work by R/C EVERY few mins so coolin should not be a problem an thank you for info on them sticks an ive been told that i am wirein up the batt wrong as i always fit the neg then the positive the off in revese is this correct ? an the 3 mm led in the gun is workin ok thank goodness an when paul looked it seems that the gunfire unit has to have about a 5 second delay before the gunfire an gun flash so my mate paul must have been lookin at it when it was in delay an also one of the probs i had up the pond was a dodgey r/c plug on the BIG RUDDER BUT GOES OK NOW AS FITTED A NEW ONE an out of the 20 plug leads i had when fitting it i had to go an pick a bad one just my luck an i also fixed the bowthruster now workin ok so all i need now is the motors then im back in bussiness an tiger can come out of drydock yay
chrisb
There isn't a circuit until both are connected, so it doesn't make any difference which you connect first.
Pete
Chris, using bigger props will just make your problem worse as the motors will have to work harder so drawing even more power, something I learned from flying electric powered model aircraft.
YEA Andy you make a good point but i was just thinkin of prop thrust as to get tiger movin i think the 33 mm props i have on are to small but will see on that but cheers for the info as i dint think of that
thanks
chrisb
Hi Chris
Just had a quick catch-up good to hear she's in the water now and I obviously hope you sort out the power issues.

I don't know what to say Chris. An exceptional amount of work and just about there. I am certain you'll sort these final issues but you must be very frustrated.
THANKS Andrew yes i hope so too
AN HI Jim yes i am as the probs on this ship are twice what ive had on all my other ships but hope to sort this soon but it may take severall trips to the pond to get the probs sorted as yes everything goes great at home but up the pond with waterload on the props is when the probs start but im goin to keep these super sized fuses an fit just one in to power all 4 motors an see if it will fuse as there is a heck of a eletric current goin through these ESC's an motors an the motors i will get will hopefully if i can get them will be about 8 v up to 15 v so they should be able to take the power with out blowin fuses
chrisb
What a terrific ship she is Chris.
It's been a joy for me to follow her build from chocks to pond!
You must be well chuffed to see 'Tiger' finally on the water.
Congratulations on a job well done. :thumb2:
Can't help with the tech. side, but I'm sure you will sort it toot sweet........

AN Many thanks Ron yes she looks great on the water an i was very pleased she dint sink as some have what others have built but to me this fuse bussiness is a dissopintment as she only sailded for a few mins before the fuses blew due to high eletric currant goin through the system an this fautly motor may have been the cause an hope 4 new motors will cure the probs an she will sail ok as rudder probs is already sorted so will find out on sept the
10 th on next warship day
ATB to you an your sir

HELLO GUYS
well the big super sized fuse holder has arrived an i know Pete who is an eletrcain may balk at this idea of mine but im goin to fit this big fuse holder in next to the normal sized fuse box an ive worked out how to wire it in an get the best of both worlds so when new motors are fitted if she still blows them small 40 amp fuses then i will remove them an leave the small fuse box empty an then fit a supersized 4o amp its special holder an then try an if it still blow due to high currant then ive no choise but to fit in a 50 amp big fuse an then see what happens an by gum its big an the wire is thick as a pencil pic of it below

I think I would have just ran a single in line fuse en each motor and see if it was the same motor every time was popping the fuse. I see that the ESC you show is up to 16v you are going to put two 12v motors across one. So 24v load on a 16v ESC...but what do I know, just those I have seen have been evenly matched from battery to motors, fuses and controllers.
HI Ian yes you are right there about fittin a fuse to each motor but up the pond i could not do that as dint have the right eqipment an it must have been done up the pond to get water prop loading an could not have done that when i got her home as no waterloading could i so that would not have been right but i do see what you mean but dint think of it as i thought as them grouapner motors had been interfered with i just thought it was them but one thing puzzeles me where do you get 16 v from do you mean the motors ratein togeather ? as ive used this set up for all my ships same motors but different ESC 's sorry my reply a bit mixed up as just had some bad news
cheers for you thoughts but with all new motors there should not be any probs hopefully many thanks Ian
