I bet your buddies are flying some type of SPAD. Check out
www.spadtothebone.com . You should be able to find someone on that site who can provide you with an ARF. There are other designs out there that are much more durable, but if your buds are flying spads, you are probably better off flying what they have. The spads fly good, are easy to build, and are fairly durable. You will have a blast. You can also check out
www.rccombat.com to find out more than you ever wanted to know about rc combat.
