1. It's a 5B
2.Gearing is all stock KM which I assume is the same ratio as stock HPI 5B?
3. All terrain tires so not the grippiest on grass.
4. 990
5. Normal unleaded with Putiline MX9
6. 25:1
7. A few shades below paper bag brown
8. Less then 9 tanks
9. Yes phone GPS, big run and even tried on tarmac....
I think it's all grip related as it wheelies on demand when there's enough traction.
