Giles 202
I am not sure where you got that a Giles will not 3D. I have a 42% Godfrey 202 that does a great job. Many TOC pilots used the Giles 202 several years ago. I think the Edge is more popular now because it is the newest of the standard aerobatic planes. You get tired of the same old thing so you change planes, designs, etc. Each pilot picks his plane for many reasons. Jason Schulman does not like the way an Edge flies, but is just his personal opinion. The Extra is more popular for smooth percision flying because it is longer. The Edge is more popular for 3D because it is short coupled. The same could be said for the Giles 202 vs the Giles 300.
Go ahead with your set up. It should do fine. Is this the Midwest kit? If so, watch the weight. I have only seen one fly, but it was heavy.
