Did more work on Spur 2. Sorted out the internal layout. Done lots of grinding to give clearance to wheels etc

Hopefully get through enough construction in the next few days to work out if its viable to enter for the champs.
Have a few bits on order that hopefully be here next week.
Contacted Alien Power on their 4260 Sensored Outrunner brushless motor 300KV 1500W which has been out of stock for a while.
Apparently they are having to use a different factory and the new style motors for these will be stocked in March - and not a mix and match with the old type :(
So I have to buy 2 new motors for Olaf
I've now got Spur 2 back to the stage of running. Haven't got the weapon built but this is a big change

Decided to test the pushing power. The gas bottle is 20Kg on an uneven dusty garage flow

Such a solid, compact robot. Nice work.
That particular type of tread on the wheels is exactly what I'm going to be looking for for retreading my Banebots wheels on Reaver. Is that just stuff you had kicking about or was it from a specific place? Looks a bit heftier than your standard bike tyre tread patterns.
Agreed, fantastic looking machine, very solid abd powerful.
I got it from Halfords. Looked for something with a close tread pattern. Werent the cheapest (about 20 quid) but great gripQuote:

Had a great time at the champs and learnt a lot about my robot
This is how it looked going into the champs - shiny

The rear motor eats brushes. I think there are a couple of reasons for this
- lack of airflow
- old motor with worn armature
First fix is I have ordered a brand new motor
We had fitted a magnet on the scoop. Boy did this work! In fact far too well (I did on reflection order too big a magnet). This was nicely solved in one of the fights where the epoxy resin broke, magnet went free. At that point Spur could drift nicely , normal service resumed :)
The scope was a temporary measure as I had ran out of time to make an active weapon. On reflection I have scrapped the idea for an active weapon. Running a couple of DeWuts it has loads of push. Therefore gone for a redesign at the front

I am going to move the TZ85's out of the rear wedge and fit to the battery box now I have a bit more space. This will give more airflow around the rear motor and make removing electronics a lot easier.
I will try and get it all back together but might be Portsmouth.
Oh - need more silver paint :)
Well took Spur 2 for a run out at Portsmouth which is nicely just down the road
Not a good day
Tested the bot on the bench at home, everything fine. Retested on the bench at Portsmouth and it ran fine.
Took it to the arena, put the link in - nothing, no response to the stick.
Went back to the bench and after much plugging and replugging it appears that one of the TZ85a's BEC's had died. Pulling the channel wire out of the plug and connecting direct onto the receiver and it worked again. One TZ85a with failing BEC
Went in for the second fight and drove into the arena. Handling was off though and after a very short run around ended up going round in circles. Eventually Beast flipped me out
Back on the bench appears that the TZ85a completely failed :(
This brings the recent total of dead TZ85a to 3 including those from the champs. One died because some swarf entered into it (of all things!)
Ordered another one - hopefully this wont go pop
Was it one of the original ones that were in it for the champs?
And I think you mean beauty, though seeing beast in with the feathers would be entertaining.
