boatman's 1/72 HMS Tiger C20 build

[boatman]

+1, but with care - most multimeters won't handle more than 10 amps.
Pete

WELL Pete if that the case then my meter wont be any good then
AN cheers Pete for that bit of info

What multimeter do you have Chris?
Could you split the power circuit of Tiger into sections and measure the current in each?

[boatman]

Have you got inline fuses from your motors? Maybe also a inline fuse on the lighting circuit, just in case.

HI Si yes both ESC' are rated at 40 amps each so ive fitted two 30 amp fuses in to protect them pic below you can see the twin 30amp fuse box with the glass top just below the main cooling fan an the motors are all wired in as a seperate circut with its own 12v 12amp hr batt

Just had a quick catch up on this epic build Chris. The Helicopter hangers look the business and the lighting really does bring the whole ship to life. I've run out of superlatives to describe this build. Suffice to say you're a very talented man!!!

All the best mate

That photo is superb , just shows the level of devotion and or madness Chris.
Hope you are both well .

AN THE LIGHTING an servos circut is again a seperate circut with their own 5 amp fuse x 4 in the PDB board pic below Si so this is how i wired up all my ships but i must admit that ive never used the PDB board so thats a new thing in the circut but thats what it ment to do distribe the power evenly through out the circuts of the ship

Plenty for thought there Chris from the guys on the batteries .
Sure you'll sort it, but at the moment becoming a frustrating problem .
You definitely need those fans to keep the kit running well .

HI John yes this is a frustrating problem as ive never had this prob before on all my ships so must be something like the PDB board that ive fitted or that voltage reducer as its getting hot when things are running but got to be sorted i just fitted the mini 6v fans just in case i may need them as no good building the S/S an then realising i need them cooling fans fitted do it would be a lot of reworking to do but all i will do is just dissconect the fans wires in the hull an tag them fans so if i do want to use them again all ive got to do is reconnect them so no probs thanks John for stoppin ATB

Strange Chris. The lead acid shouldn't cause a problem, even under load, if they were weak and not holding a charge properly I would expect a drop out without much heat.

I remember the fused PCB, rogot about that, sorry. Stumped to be honest, only difference to your other boats is the PCB, maybe you need more heavy gauge wiring or the board is goosed.

Hope you manage to figure it out.

HI again Pete this is my multi meter i presume what you mean

AN Pete that how ive designed the power system around two batts as ive done this on all my ships so one batt to power all asserorys an one batt to power the motors so its a two circut system an ive never had this problem before as my nimtz an my now norfolk are both desinded like this an they ran lovely

AN IF it comes to it to have more power than i may fit this 20 amp hr monster batt but its so bloomin heavy but the ship is desinded to take the wheight but this is only as a last resort an you can see how big it is an the scales when i wheighted it went right off the an hit the stop but have to be very carefull with this if the strap brake an it drops on our feet it would break the foot an then hospital job

Might be the voltage reducer, though the byproduct of dropping voltage is heat - simple way of dropping the voltage is by fitting a 6v light bulb in series (the wire comes from the positive side of the battery, and then carries on, but not to the negative terminal) also acts as a fuse

HI Paul yes hanger bay does look good an even better when i fit in x 2 1/72 seakings bein serviced by the ground crew
( Suffice to say you're a very talented man!!! ) well Paul im beginning to wonder about that i may have over reached myself on this ship

Chris, not really at all 'up' on electronics, just got a sort of grounding in electrics due to running old motor bikes, and fault finding on them.

Hi Chris
I really hope this power issue gets sorted. So much has gone into this amazing build it seems so unfair that you have such a problem at this stage. Keep at it. You have the skill, the patience and Jen to support you :thumb2: :rolling:
