If the doors are removeable, they only count against gross weight, not empty weight since they are not required for flight.

I don't mean to steal the thread, but you have experience with the Nano and I suspect at this point there are more people like me that are interested than own one. I'm curious if you have flown a gyro before or did you get any training before flying the Nano? How many hours have you flown it now?

Was that you flying the yellow Nano on YouTube?

Thanks for the update. I had no idea my son had left our basement and made promises to you!

I would welcome seeing pictures and video!
