I've been looking at the GSP Zero and the Ultra-RC zero and the price span is so much that I could get the GSP Zero and put retracts on it and still come out looking good. Now I'm sure that the Ultra-RC Zero is probably a better kit from what I read on the forums but from personal experience some times a higher priced plane doesn't always hold true in being the better quality plane. I really like the Zero because when I go to fly-ins and meets you don't see a lot of them out there and I like to be a little different. I've got other projects on the table at the monent but I'm thinking ahead for a winter project.

Note:
I had a CMP Giles 202 73" and same here, no manual just a print that had exploded
views. It did have the CG and the throws.
