    Well an interesting Stevenage
    Spur 3 had plenty of push and was fast
    Need the front scoop to help throw some robots about
    At the end of session 1 a tyre came off - not enough screws and need to be pan head
    Fixed that
    Setup for session2 and had dramatic smoke coming from the bot. Crew did a great job of grabbing the robot and racing outside
    After a blast of CO2 worked out it was not lipo but a TZ85a. Once stripped down I could see that one of the motor bolts had come loose jamming the gear and stalling the motor. TZ85a vs NTM 5060. Time for a HK order
    Happy with the day though. Robot shows alot of promise and can focus on fixing various things

    Alex drove Spur 2 and that had a good day after working on strengthening the drive line. It did shed a tyre. Looking at them the rubber is getting end of life. Therefore it starts Sunday with new tyres

    Nuts had a great Saturday , Rory can write that up

    Been a while since I posted on this

    Put a front scoop on Spur 3 and locktite in all the important places. Should be ready to roll

    Started collecting the parts for Heavyweight drive gearbox. Since I was in the US I picked up some Neumotor 8019-150KV
    Its 1.2 Kg of motor goodness
    These are chunky and much more substantial than the Rotomax I was looking at. Once I have finalised the gearbox design I will be off to the local engineering shop for some milling

    Those motors leave the Rotomax range for dead! Any thoughts on the ESC you will use with them?

    So I see - I am using A Kontronk Kosmik 200 with my 8019 - its powering a weapon so I don't need reverse. The MGM controllers are well made and the tech support is super helpful; they offered to do custom code for me. VESCs are probably borderline for power handling and the guys over here are not sure how they will handle high pole count motors.

    Had a look at the MGM's, they are nice but pricey [increasingly so with the pound dropping!]. The Castle is looking more of a possibility. Rory was interested in fettling the Aliexpress. For now I will design space that will take either, have enough stuff going on to keep me busy

    Thinking about wheels, its been going round and round in my head

    I made wheels for Spur 3 from Nylon and its was a pain, modified Banebots for Spur 2 and blue tyred jobs for Spur

    Having seen castor wheels fail spectacularly at robot wars I didnt want to go this way for my heavy. Spent a ton of time trawling round looking for pre-made wheels I found these at TEP Technica Ltd https://www.technicawheels.co.uk/
    They are worth a look

    Even better they were about 20 minutes drive away



    Onto the next bits

    Well, I sat these 2 side by side and the size difference popped out (not surprising)

    On the left is a bearing support and pinion for a P60 Banebots gearbox. On the right is a BB220 gearbox an pinion
    Both will be doing the same job but in a feather and heavy. Just hope I dont mix them up
