Be afraid my friend. I love this model and have cartwheeled her many times. The stock landing gear sucks and relies on the spats to hold it in place. That is why you glue the wooden side panels inside them. Unfortunatly they aren't strong enough. I ended up fabricating my own gear with suspention using very small aircraft tubing. Even with my custom gear it is still very difficult to land. The problem lies in the bounce. Unless you grease it on you will bounce the airplane and due to the arrangement of the gear it will cause your angle of attack to increase dramatically. At that point the airplane pitches up and runs out of steam and lift, usually dropping a wing and doing the famous cart wheel. The key to survival with this model is to "GO AROUND!" on the first bounce, don't try and save it. Full power with a little right rudder, take her around and try again. I have an OS 120 also which is perfect for this model although 100 ccs would be nice at that moment of go around. I recommend finding an area to fly with plenty of room. I started out on a dry lakebed. I am going to try and replace the factory foam wheels with some softer Sullivans or something. Anything to cut down the bounce. Stick with it though. The model is a real crowd pleaser. Good luck
