I agree with the above advice. I admire your resolve to fly the plane yourself (I have ALWAYS performed the initial flights on my planes.)

What I have to add is: Get a spotter.

In other words, have an experience pilot stand with you when you fly. They can give you advice and offer help if you get into trouble. It is VERY nice to have an extra set of eyes on your plane, especially if problems start.

I've been flying for six years now. I am self taught. I flew over 400 flights last year. 300 on giant scale. I fly aggressively, low 3D, IMAC, pattern, you name it. I didn't have a serious crash all of last year other than one or two hard landings that tweaked my gear a little. I'll keep tooting my horn, I am probably the best pilot in my club of 150+ members. Why am I tooting my horn? To make this point... I still use a spotter for maiden flights.

Cheers
