With the stuff gathered weeks ago I was finally ready to enjoy one of my cars here on our lawn.
The first target was finding the correct gear ratio to run my Kyosho Ultima SB on the grass without overheatings.
Unfortunately the Ultima motor plate doesn't allow the use of 18t and 19t pinions without using a larger spur, so I had to switch to a 20t pinion that seemed to be a good compromise.
Unfortunately something went wrong and I've ground the 76t spur. Without spares in my bag: end of games.
