Bill,
As a relative newcomer (started in 2001) to carrier I would suggest the following if you want to fly in the event.
15 carrier is easy to build etc but the planes are actually harder to fly. They tend to be light and move about alot in any wind. What I would recommend would be to get a Brodak Guardian kit (or just the plans) build it with a couple of modifications that I got from Bill Calkins (he designed the kit). Put the controls on the bottom of the wing, not internal to the wing. Much easier to get to and adjust and you can get more line rake. Cut 3/8" out of the fuselage height, yeah just narrow it by taking a 3/8 strip out of the middle. Reduce the stab height by the same amount. The rest is just as the plans show. I might also suggest a single uniflow tank behind the motor and not the chicken hopper. I had some problems getting that to work right for me. It could have been just me not know what to do though. The slider works well and the hook mechanism is simple.
Get a Thunder Tiger 36, they are relatively cheap and are pretty powerfull yet very reliable. Reliability is really the key both in the motor and the plane. Many contests have been lost due to simple things not working correctly.
With this combination you can do well in Sportsman class in the first year of trying. If you keep the plane relatively light (under 40 oz) you should get 70 to 80 mph high speeds and the plane is capable of 3+ minute low speeds or more with some practice. 70 mph with a 3 min low and a landing is a score of 250 pts, very respectable in Sportsman.
One of the key elements to learning carrier, and getting into a hang is balance of the plane. I am convinced that anyone can hang a well balanced plane with a little practice. A badly balanced plane is a recipe for frustration. you want it as tail heavy as you can and still be able to fly it in high speed. In other words, the cg is very near to tail heavy but you can't have it too far back. I can't fly a beginner stunt pattern but learned to hang the plane without too much trouble. You don't have to be super flyer to do it. It just takes some time and practice. The other key is that things work smoothly, slider, hook and throttle. Get it right on the bench and the flying will be easy.
Let me know if that helps/encourages you or you have more questions. I like to promote the event, its a fun time and something a little different.
