My personal throughts were to have 2 classes.
One being the Parkzone type Foamies, 480 size motor,cheap and disposable or easily repairable foam.
The other being a 25 size 2 stroke Glow of the type the Battle Axe is. The are other types of combat planes out there we could use.  I think even a design your own would be cool.
Here's a link to a fun combat event maybe a little large for us but you can get the idea.
This is "Total Destruction Combat in Mass

At the last meeting I brought up the Idea for RC combat at the field. I used to do this back in the early 70ies with a Honker powered by a TeeDee 049 it was a blast then.
Recently  I had a chance to do it again down at Liberty.
Most of the guys were flying Battle Axes power by OS 25 engines, but some of us were in the mix with Electric foamies.
I flew my old  PZ Corsair it lasted about 3 minutes before being taken out by a Battle Axe, but I had a blast. The Idea is to get the streamer not the Plane   
I looking to see if this club would have any interest in starting some combat. maybe 2 clases: electric fomies and 25 size Glow power.
attached is a link to my you tube channel showing the planes eye veiw of Combat "The Last Dogfight"  WARNING  it can make you dizzy watching it ~4 minutes long.
you can see what kind of donny brook it was.
