Chip thinks the 220 would be a great choice as well.............Cant wait to see how the 220 does on this Cap......My only concern is the ground clearance with a 20" prop....My flying field is not perfectly flat... One more thought....I changed the CA hinges to stronger pinned hinges (25% size). I have a similar size extra 300s that I used CA hinges on and cracked them on all surfaces (at different times of course)......EMVIN.......
