I use the cheap little 250 canopies from HK. I actually just bought a fusano for one I am building for a guy. And the link for the pics of the Cx with canopy are here. Post 697. I have a fleet of these things and everyone is different. Even dual swash and dual swash flybarless brushless versions. My favorite boom upgrade is the Xtreme boom mount using a simple CF rod inside the boom mount after I cut off the exterior boom mount tabs. Then I use either 450 cf stabs or 250 cf stabs depending on whether it is for outside flying or inside.
