Just wondering if anybody out there is seeing good endurance times from their uavs. I am trying to get about 20-45 minutes of flight. I know that is a long flight time at 45 minutes but it is uite reasonable as well in some competitions. I was building an electric senior telemaster and then making a longer dihedral wing foil to the extend the lift and overcome some of the drag on the smaller wing.

If anyone has any thoughts about the airframe I would appreciate any responses that you can send. the UAV will have less than a kilogram payload with camera and autopilot.

Thanks,

Dan
