He's still not said what he's sending me yet but from what i can gather it's just going to be a service pack 2.
I'm getting a new pair of knuckles when i get the car back but the one that popped was OK so i think i'm going to re-use that, wait until it pops again, then put the new knuckles on with the Arrma balls and see how i get on with them, i know it's not a permanent fix, but hopefully they will hold on long enough until the "new" batch comes out. It's not like i'm jumping it 20 feet in the air or anything i think the highest it will get is about 5 feet where i'm using it at the minute, I'm scared to take it to the bmx track. I guess i'll just have to work on my landings 😁 to be fair though i didn't crash it once in the 40 minutes i got out of it and only 1 "bad" landing that didn't break anything!
