The set up for the 108 mph is Supertigre 61, stock muffler, robart retracts, JR radio., he also had a run of 102 mph. didn't get mine because my engine went lean and then some engine problems so will try again this weekend. The other plane which has the same setup as mine was having some gear problems so no speed check there. These NitroPlanes Bobcat will go faster and I'm expecting 115 mph from mine. This is a level pass so the speed is good for flat out speed. I will post more when we fly this weekend
