I bought one of these after my wife gave me a Saito 100 for Xmas. The Saito works very good but the plane is very underpowered with this engine I would go with at least a 120 or 150 if I had the choice. I know it is a scale type plane but it should have at least a "little" vertical and it doesn't with the 100. The plane is also one of the worst flyers I have had in 20 years. I know not many would agree with me - maybe it's just not my cup of tea - but flying it is about as exciting as "watching paint dry".
