i have this plane. for a year now. ys 63 13 6 apc prop. when i was first looking at it. everybody was saying how ugly it was. ill tell u its not ugly. its a nice looking plane for the money. it flys great and is alot of fun. it lands nice. if i ever got another. id put a saito 100 in it. the 63 does real nice. as ys is great. but a bigger engine would be able to hover the plane. the 63 will just barely hold it at wide open. so its not enough to hover and pull out of it. but it flys really well. im sure ud like it. knife edge, snaps. this thing will even do a knife edge loop. but it does not have quite enough power to take her to the top. just about. but a 100 shed be bad......... hope this helps.......
