I have an Arrow but I bought mine without an engine then put an O.S. AX 46 wich is more than enough power running a master airscrew 10x8 prop. I set mine up to zero thrust angle with the original clamp style motor mount. You have to use a little right rudder on take off but thats the way I think it should be. If you cock the engine slightly to the right you will have to use less rudder but this is a trainer also and part of learnig to fly is to use the rudder. Oh by the way snapping an arrow is fun just make sure you have the wing on good.l
