hsimmons, i just started flying my first giant scale. learned its a rascal to get started. i made a electric starter. in the process i decided to make a positive hold down that is working terrific for me while i start my big bingo by myself. it locks the front wheels in place while im starting and cant be released untill i go to the rear of the plane. if your interested i can shoot a photo of the hold down and email it to you. you will see in the photo that its very simple to make and takes the fear out of that 22 inch prop spinning in front of me
