    How are you running the NTM-4248 on 12S? A 5S rated motor will melt pretty quickly on 12S, or are you just powering them from one 6S pack?

    You are looking at the wrong thread; check the next line down for the 3/8-24 drill size. That chart says a Q sized drill which is right between 21/64" and 8.5mm :)

    Sorry, a 5/16" hole is too small. The tap will be cutting more than 100% of the thread depth, which is an excellent way to snap it. You are looking at the hole size for a UNC 3/8-16 thread.

    The bore is already 3/8" - the tap will slide right through. The centre of those hubs is actually a plastic bushing so the bore diameter in the aluminium is more like 0.5". A 3/8-24 tap needs an...

    The hubs have a smooth bore are designed to run on a 3/8" axle, not a drill motor. You need a hub with a thread in it - I'd get a local bot builder with a lathe to make you a set.

    1) Hot-melt glue - its ugly AF but works. Most builders use 3 wire RC cables with a single connector at each end.

    2) You can usually just solder up a Y cable but a more elegant solution is to...

    Unless the batteries are different voltages, there is not much point in having separate lipo packs; they are not likely to become faulty and if they do, it probably means a lipo fire that will stop...

    You can get extra long shafts for the Banebots P60 gearbox; making your own shafts is a precision job that needs both a lathe and a mill.

    There have been some successful bar spinners using the A28-400 and it has heaps of low-speed torque, so I don't see why not.

    The A28-400 motor is (or was) a very popular motor for lightweights. They run very hot, so the new fan-cooled version is a good option and you definitely need to get a spare set of brushes as they...

    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....

    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.
