The whole reason for this came about last summer at our field fun fly when we had the drag races. I had the stock head setup and I moed down 11 oncomers with the rappy. I was crowned Drag Queen. I was scared to death standing behind this ship as it spun up to 2150 ready to launch. I was convinced it was going to explode on launch. It never did but now I will feel much more comfortable drag racing this ship. This cost me all of $150 for the used X-Cell parts.
