Based on what I found on ze interwebs it seems to work on the same scale as traxxas.
Also Florian Kreyssig uses 50,000 Reely on his 5x5s apparently (probably in the core) which gives further credibility to my claim. (

I have 5K maybe use it for the core and get 30K for pieces, or what other combo would you suggest? (e.g. 30K for pieces, 50K for core?)
