Hi. I'm getting a hornet for Christmas and I've read here that it's a good idea to upgrade to ball bearings. Well, as I'll be putting it together over Christmas, I thought it would be a good idea to get the bearings ready before the build process starts and not have to order them half way through the build. Please, can someone tell me how many rubber sealed and metal sealed I will need? Or is there a complete bearing kit available that i could buy?
Many thanks
