Juanjulian, I introduced combat to our club last year and this year we have 16 signed up but only 6 on average show up for our weekly sessions. I designed a very cheap combat plane set-up and keep the rules simple. Throphies for 1st 2nd,and 3rd as well as weekly high score winner plaque keeps the real competitors interested. Having our club sponsorship helps as well. Our set-up is SU-26 and EXTRA profile foamies ($10.50 bought in bulk) and electrics from HobbyKing at $35. The electrics are reuseable if plane is damaged beyond repair. Planes are quick to build,usually 4-5 hours. The planes fly at around 45-50 mph and very manuavorable. The thrust to weight ratio is near 2:1. With only 4 catagories for points,scoring is easy and fast. No judges and each competitor keeps his/her own score with verification. We fly 12 sessions per year with 5 heats per session. That's 5 hours of combat flying and a plane is totaled on average every 50 minutes. Not that bad and usually they are repairable at the field in 5-10 minutes. We use 15 foot streamers on 5 foot cotton leaders. All these things add up to a sucessful combat event that endours. But even then not all will stay at it and attendance can be sketchy except for the real hardcore competitors. Hope this helps.
