I recently purchased this kit for $40 from Great Assembly, and was really impressed with the quality & precision of the CNC work. I'm currently running this setup on my OS .15 CVX Hyper w/19cb & 73t Delrin spur. I am very pleased, and see a big difference in the responsiveness of my Maxx. Engagiing of the clutch is instantaneous, and I have seen no unusual wear or heat discoloration on the cb as many have claimed would happen using Al. shoes. All in all, I believe it to be a great kit, a tad pricey but the guys at GA stand behind there products...
