You might hop over to rcgroups, there's a whole section dedicated toward stuff like this.
Please be sensible about it, there has been a lot of bad press over the past few years and the FAA has really been breathing down our necks. Flying long range without line of sight with a spotter is illegal, same with flying over heavily populated areas or near airports. Stay away from full scale planes, stay away from roads/traffic and be mindful of private property, there is risk of draconian regulations affecting us all.
