Check out the SIG Sundancer. Not scale, but could be a home built. One in the club with a 50cc gasser and it flys a BIG envelope... Slow and gentle, but will do reserved aerobatics. I fly a Speedster with a Fuji 23 ( a 50 might be a bit too big) and is is a gentle flyer with no bad habits. Is acutally better looking than the scale plane as it is a bit longer and thinner. I had only one problem with kit, Formed windshield was 1/4 inch wider than fuse, no way to modify, so ended up making sheet windshield. Looks ok form 50 feet away. Cliff
