For a summer job I teach model rocketry at a summer camp, obviously after 8 weeks it has gotten old so to keep it interesting for me and the campers we try different things, because of the nature of rocket engines they produce alot of trust and move at high speeds (exactly what makes them interesting) the problem that this creates is a small change in the aero dynamics quickly becomes an extreme change in direction, this makes crashing nearly inevitable (any one with model rocket experience will tell you the flight seldomn goes the way you expect it to.). As much fun as a radio controlled rocket sounds it also sounds impractical (not impossible) if you want to try it look into basic stamps and light weight servos. Something I have found the kids like and is more fun is remote controlled air craft we built a couple of these one summer with the intent to race after a dissappointing finish in the first race a friend and I put rocket engines with a modified ignition system on ours and won (although we overshot the target by 500ft) If you try this make sure the nose is pointing up at ignition. My advice is find a long stech of private land to use any thing used on public land must be approved usually by a fire marshall. Good luck.
