Is there a weight limit? Is 260lbs too heavy?

On their website, 260 lbs is the cut off for the high flight, which is where they send you higher and faster with the instructor.

From the iFly website: "All flyers must be in good health and physical condition. All flyers must weigh less than 300 pounds, and flyers who weigh between 260 and 300 pounds must bring this to the attention of an iFLY representative as additional restrictions and instructor scheduling limitations may apply."
