@metalman;

If the capacitors are so big that they can store the energy from braking, they can smoke the controller as well, so you need another fuse to prevent that.. (not saying that you need a fuse, you actually don't need a fuse at all)

So if you completed the truck it's more of a driving fuse than an RC car.. More of a Radio Controlled fuse actually..

I have a fuse on my system as mentioned above. It doesn't seem to popular on this forum though. In my background in electronics, you are taught to always fuse a circuit - so I guess I'm hard-headed in that sense.

Anyway, from what I've found around the 'net, I can't find any other referenses to fusing a brushless controller being bad, unless you are using a BEC as stated here:

RC Power FAQ

I'm still looking...after all, my polys did cost more than my controller, and the fuse will protect them in the event of catastrophic failure.

Perhaps, as mentioned in the link above, the issue being mentioned with breaking generating high voltages is due to people fusing between the controller and motor instead of battery and controller?

Serum - did you get this info "from the horses mouth" or other bad experience? I'll take the fuse out in a heartbeat if I can find some good evidence.

It is about electronics, and my schulze 18.97 died because of loose connections with the batteries.. It died after i braked.

If you want to keep you batteries intact and don't worry about the controller, use the fuse..

and it is logicall that the motor works as a generator, it simple uses the low, near zero Ohms of the batteries for braking. the fuse will end in an endless resistance, so the energy can no longer be stored.

Those spike killing diodes might work well though. you can put them over the 3 wires of the motor.. or on the 2 batterie wires. they simple short when they get above a certain voltage. and they can absorb 1500 watt spikes and you can use them paralell. I will get back on the name of those things

They are called transil diodes.

Just for you Serum, as I still remember my old metal Tonka crane.
I just loved that thing

bought this for my Lad. he loves it, when I let him have a go :D
Its not a patch on the big yellow crane, although the exhaust stacks are still made of that bendy rubber.:o

The mighty crane?!!! I had that too!!!

I also had a Mighty Front loader.. He didn't survived the concrete i transported with it.. (my dad was building a new house, and i just had to jump in for help, you know how it goes..) Being 4 years old, owning a front loader of that caliber, you just have to show off..

It too had two rubber exhausts.. Mine is still going strong..
