    Nothing wrong with having as many fuses as you want. The fuse is only in the rules to protect the Lipo from the rest of the bot and prevent fires not to protect the electronics.

    This part of your post is confusing me; 'split the circuit after the removable link before a pair of fuses'

    Does that just mean you want a separate fuse before each drive motor ESC? Not many...

    That is absolutely fine, they don't even really have to be charged exactly the same. Its when you connect Lipos in parallel that you have to be careful.

    Great event report Andy, that weapon hub took a real beating! You might consider 2024 rather than 7075 for the hub; its not quite a strong but it is also much less brittle and less likely to crack....

    It can be a LONG walk to and from the car park to hall 20! If you are lucky, car parks N2 and N3 will be open (they weren't for the last year's GSL event). Even then its not a particularly trolley...

    What does the gell-wrapped UMHW achieve structurally? If you want more strength and rigidity, just increase the tube diameter and it will probably be lighter than the plastic core.

    Go to the Roboteq site and download the manual. From my experience with a single channel Roboteq, it will run straight out of the box but a little customising will make it better. If you go that way,...

    It depends on whether that 94.5A is the continuous or the peak rating. Most packs state both and the peak is usually between 1.5 and two times the continuous rate (if the peak rating is not much more...

    The fuse is there to prevent lipo fires, not protect the electronics. The fuse rating is chosen to be somewhere over the maximum current likely to be drawn by all the ESCs simultaneously but less...

    For prototyping at least, why not bend some really heavy duty copper wire to shape? Its cheap 'n easy to get started with.

    Do you really need that high switching frequency? For the large, higher impedance motors that this ESC will be used for, manufacturers usually recommend lower switching rates. The ones I am...
