550,
Welcome to RCUniverse. You were very lucky to have your neighbor give you that RC plane and engine.

Unfortunately, the engine is definitely too small for that plane. It might have enough power to move the plane on the ground, slowly, but does not have enough power to fly it.

If you are serious about getting into RC flying, I would suggest a couple of things.

1) Flying an RC plane is MUCH more difficult than you think. The best idea would be to get a trainer type of plane, and find an RC club close to you. They will have instructors who can teach you how to fly the trainer. It might take as few as 4 or 5 flights with him, or as many as 40 or 50 over many months.

Most clubs require AMA membership (a national organization that provides liability insurance). AMA is like $58 per year unless you're under 16. You will also have to join their club, which can cost anywhere from $25 to $125 per year.

2) The plane you were given is not a trainer type plane and would be quite a bit harder to learn on. An instructor might not even be willing to teach with it.

For the trainer, engine, radio equipment, and misc. you can expect to spend anywhere from about $300 (if you can find all used stuff), to around $400 or $450 if you buy new.

If you want to sell the stuff you were given, the 20 engine, depending on what make and model it is, might be worth $30. The plane itself might bring $100 if it's nearly perfect. You can try to sell them on RCU in the For Sale forum. (Look for the right categories.)

(If you have radio equipment, transmitter, receiver and servos, you can use them in the trainer.)

3) If you try to fly that plane or almost any other without help, you will almost certainly crash and destroy it. At the very least it will need a lot of repairs before it will fly again. The plane you were given should NOT be flown in a school yard, or soccer field, it is too large and too powerful. You could seriously injure someone or damage property. (These can fly many miles if you lose control.)

I'm not trying to be mean, and I am not trying to discourage you. We want you to be successful so that you can have fun with this stuff.

If you don't have a source of income, or parents who are willing to buy you stuff, there are a couple of alternatives. I usually don't recommend these, because they don't fly all that well, they don't have the same controls as larger RC planes, and the radio equipment doesn't work with anything else. But, there are a few reliable, inexpensive 3 channel planes, like the FIrebird, Fighterbird, and Aerobird, that you might be able to fly on your own. They are small, foam electric planes that cost from around $70 to $150 complete with radio.

You will crash these too, but they are very light, can be flown in a large park, and because they are foam, they can be fixed pretty easily. They do NOT fly in wind! If the wind is more than about 5 mph do not fly until you have learned to fly it well.

Look around on this site, or do a "Search" for "Firebird", or "Aerobird", you'll find a lot of information.

Do some research on anything you might want to buy though. There are MANY inexpensive planes out there that will NOT fly, so be careful.

Good luck, and let us know what you do!
