I am gonna run stock, any suggestions on changes to the car for a Challenge race ?
Thanks
HPI Challenge "Stock" means Box stock. You can change pinion. But you have to run a HPI tire and rim. You can change shock oil but you have to run the super soft silver springs.
The silver springs make the flexy flyer seem like a 1970's Caddy. It floats over bumps rebounding forever then when you turn the chassis basically barrel rolls over itself.
