"Thank you for the ebook. This book was as good as the helicopter one if not better. I wish I started with your airplane ebook first and then the helicopter, because your airplane ebook explains all the parts of a plane which you can use that knowledge for understanding a helicopter better! Anyway, perfect job thank you. I wish you and John would write more books to document your knowledge for novices like me.
