I've got the Burrito and the Extreme flight edge 540, both on 46's. I think the Burrito is better with the 46. I'm getting a Saito for the Edge 540. I'm not happy with it on the 46. Both are fantastic planes, but it's just my opinion with a 46, the Burrito is better. The EF Edge really needs a 50 2stroke or bigger 4 stroke to do it's magic.
