Good evening to all modelers.
I have to thank Roger for opening this discussion, because it is very interesting and brings me back to a doubt I had. A doubt that I would like to remove.
I went to look at the photos (because I didn't remember and I did it before unscrewing the covers) to see what threshold I chose for the fuse.
As you can see in the photo I put a 20 amp fuse (connected to the fastons).
It has never jumped until now but I'm afraid it's too low a threshold.
I would like your opinion and advice.
I did some tests to test the current intensity and chose a value double that at which the motor runs in water, almost at maximum power, without impediments.
The engine is a Graupner Speed 600, the battery is AGM lead, 6 volts 4.5 Ah.
