Sadly as I expected I havnt been able to spend much time in the past couple of days working on Trojan but I have made a few important decisions.
For the drive in Trojan 2 I had about 3.5 gear reduction with one sprocket system going from the motor to the two wheels.
To make things more reliable I have decided to go for two separate systems. First reduction through spur gears to the front wheels then 6mm chain and sprockets to the rear wheels.
Already done some work towards this by constructing one of the wheels and nearly hacksawed all the sprockets. Lots of arm work needed!
After watching some past videos I realise that having the biggest motors in the world wont mean jack if you dont have grip to take advantage of the torque. I have more grip but I still will be wheel spinning constantly. So I decided to get more speed and changed the reduction from 3.5 to 2.
This will make the robots max speed of 20mph! But should still have the torque to push other robots quite easily. Should be entertaining!
So just ordered some sprockets and now doing 2 chain systems. If things are a bit crazy I can just go to the
sprockets and the 3.5 reduction.

Also thinking about the lifting prongs at the front and it might be tricky. But I think a worm gear reduction from a drill motor will have good results. Needs to be an afterthought as I need to work out what weight i have.
Also had a quick sketch up in 3d of the next feather. Bit more impressive looking but probably won't be as good.

This weekend will be set on finishing the chassis and all the tiny little plates that attach around the wheels.
Wow I might even look good to possibly make Guildford but personal promises need to hold up. I am not going to rush.
Few questions
Is 6mm chain fine? I used to have ⅜ and that was far too big
Suitable featherweight armour nowadays. Ali, ti or steel. Would 2mm steel be a deathwish on the front plate? I had 3mm ali plate on the top for a long while and seemed fine against little hitter. Last time I fought a featherweight spinner was back in 2003 so my experience with them is limited
Lastly how do I set my avatar to appear in my posts?![]()
