ok just to cover a few things in this firstly the sabertooth is not the best known thing for reliability, the feather 2 is a tank i ran one in blunt force trauma and it made it to the knockouts at tge fw chamos with no issues what so ever

if you ever want to step in the arena with any form of spinner ditch the aluminium and may i recomend hdpe insted you can buy it in sheets and cut ut with a jigsaw and there are a long list of very robust robots made out the stuff we used 20mm hdpe on eric and it withstood big nipper and Gabriel having a good go

the final best peice of advice i can give you is get it built, get to an event and speak to other builders we will all gladly give you our knowlage from our mistakes but dont be afraid to make your own

good luck dude and see you out there

btw if the builder of get shreckt is there and you wish to speak to him he really loves tinned peas they will tottaly get you on his good side
