Something else to look at is a 90 sized engine. The Super Tigre 90 is a great deal at 119 at Tower Hobbies. The good thing with a 90 is that it weighs the same as the 60 and has the same size case, but you get a lot more power. Its like the difference between a 40 and a 46 sized engine. Same size and weight, so there is not really much reason to buy a 40 or a 60 you are better off with w 46 or a 90. This will allow you to move to a bit bigger plane later on as well. You dont have to use all the power of the motor but its impossible to make one stronger.

This advise a 50 cents might buy you a Coke.
