If you already have some experience flying models and just want a little rocket for under $150 including the engine, try the SIG "Wonder". I have built 2 before and am working on my third... well will be working on it when my house is finished being built. The plane is very simple. It is hand launched and has no landing gear, just a landing skid to protect the belly upon landing. They are designed for air combat which makes them fast and agile. I have a few other models, some scale and some not, and the wonder is by far my favorite for FUN flying. My first two had recommended size engines in them, the first a .10 2 stroke and it was good for learning the handling of the a/c. the second had a .20 which really put some speed into thing, and also made it very hard to keep it within sight because it has a span of less than 3 feet. My third one under way is built around an O.S. .40 which we will have to see how it works. All that i have to do is cover it and off to the field i go. I am actually really scared to fly it because i can only imagine how fast it is going to be... that just means that the engine will be deeper in the ground and harder to dig up when it goes in. Anyway, the kit is CHEAP at under $30 if you look around, and you can have an engine for less than $100. It also only requires 3 chanels, so a radio could be had for very little as well. Not bad for such a great little bird.
