I just installed a OS50 in my raptor 50. I'm only getting 5 minutes of flight from a full tank. What is wrong? I know i should be getting at least 15 to 20 minutes easily. All i'm doing is hovering and slow fwd flight. No fancy aerobatics.

Does running the fuel too rich cause this? Wow, if so, it can cut my flight time by 1/3?
Maybe there's a leak? After about 5 tanks, I called it a day, there's fuel everywhere. Alot of cleaning up to do.

Thanks in advance for you help.
