    What motor are you planning to use with the BB220? I found that the rear plate on the older P80 gearbox was hard to use for anything other than the CIM motor and ended up making my own replacement.

    Since I don't have enough pain, misery and frustration in my life I am going large brushless outrunner
    Start-up torque will be interesting - my usual approach is go big and low KV on the motor then sensorless
    Be fun finding an ESC that doesnt turn into a toaster and dont get me started on VESC.

    Did i say I don't have enough pain, misery and frustration in my life

    Got my custom Neumotor shafts back along with my broached gears. I can now do a final measurement check and put the order in for waterjetting
    This will allow me to put the 2 drive pods together

    No banana's were harmed in the making of the new shaft

    The work was done by D.C.V. Precision Engineering at Aldershot

    Is this robot going to be the new Tornado/Storm 2? Those look absolutely vicious for drive motors.

    I love the idea of interchangeable weapons. The Battlebots teams seem to put alot of effort in that area
    You then have to think about the drive system being more a weapons delivery platform which is a bit of a challenge as a really like small compact robots

    My first objective is to get the drive pods completed and then do some basic driveline testing. The choice of ESC is quite limited as I dont want to spend MGM money but then smoking a few Flier's you could of bought them. I am hedging my bets and allowing Ampflow A28-400 to fit if needed but I want to persevere with brushless. I got there in the end with feathers with alot of iterations and have a quad 5060 feather in the works (yes , stupidly overpowered but who says spending days building something with the expectation it will get smashed up is rational)

    Nice! I'm quietly trying to make the move over to brushless too. Bought some for my next featherweight and I'm looking into heavyweight weapon drives - if Ellis with Pulsar, and the Big Nipper team can get them working well, then hopefully so can I.

    I do like the Battlebots style, it feels like a fresh approach with a lot of diversity. Admittedly a lot of BB teams have much more funding than us, but I definitely feel there's a place in Robot Wars for lighter-armoured, fast aggressive machines, as we've seen recently to some extent. All the best with your brushless endeavours!

    That custom shaft looks excellent! If you are planning to run the motor at its full 53V rating, you need a 300A ESC to cope with the motor's 15KW peak rating and there are very few choices. I have no idea if its possible, but simon K firmware on the Hobbyking Fatboy2 ESC would be a cheapish option.

    It gets tricky for sure. I want to run at 10S which narrows the choice even more. There are a number of 8S controllers around e.g. Big Nipper team run ToroRC Beast with custom software. The Flier ESC's due higher voltage but are the typical generic Chinese ESC. Some heavies have used them e.g. Sabretooth. If Brushless Rage was built that would be nice

    Fliers should be SimonK compatible. Just need the right flavour of code. Go for the 400a ones at least - they have the same fets as what even hobbyking calls a 250a (dlux) esc.
