If there isn't any combat in your area and you and some friends want to get into combat, there is no better time than now to go to the SPAD website. Download the plans and build a couple of combat planes. If you want to use 40 or 46 size engines, build Daggars or Darts, if you want to use 25's build HOR's. This will give you cheap airframes (from 10-20 bucks) to play with. Coroplast wings generally only cost about 5 bucks to repair and they are tough to last through midairs.
Now it is true that under the right circumstances you could loose battery, radio, servos, engine and airframe, but I think I've only stripped several servo gear sets, I've never lost an engine though I have replaced throttle arms and I've never lost any battery or radio. On the other hand I knew a guy that lost 2 receivers and a battery one weekend. More often than not you will experience airframe damage and that's about it.
It is addictive and fun, SPAD's keep it cheap. Just remember to keep a little safety in mind and you'll have a great time.
