Thanks all for the help. I guess the way I see it is:

1- The 25cc is a little on the small for the 1/4 GP Giles 202 & GSP Katana 1.4 If correct what would be a good choice for these birds. I have a US41.

2- Would the 25cc fly a 1/4 cub of something like that? If so, which one do you suggest?

Thanks, Randy
