Combat anyone?

I've been flying 3D and it gets kind of boring when I cannot progress beyond the rudimentary first stage. So I've been trying the Flea, flying the Red Butterfly, and thinking of more 'fun' models. Last Sunday I think that flying combat would be cool. I think it would be interesting if two or more models can be in the air trailing streamers behind them and each manouevres  to cut his opponent's streamers.

Rules have to be madeup, models should be durable, fast and manouevrable, cheap and look something like a plane that actually saw real combat.

I'm thinking of simple profile fuselage, flat compressed foam wings, 1/8" balsa stabiliser and elevators, beefed strategically with 2mm ply doublers, 5mm diameter CF tubes, 2.5mm diameter CF rods (slips inside the tubes). The wings need not have dihedral to keep things simple and maybe positioned somewhere closer to the centreline of the model for perhaps better flight characteristics, convenience, durability, and strength.
The motors should all utilise the cross-mounts so that motors can be swapped easily. This in turn is to be fixed to 3 or 4mm plywood firewall with bolts and blind nuts. The firewall is supported on 2mm ply pieces which is glued to the 2mm ply doubler. This feature's advantages are:
  • easy swap of motors upto 28mm diameter
  • easy placement of 3S1300mah batteries, ESC and RX
Two servos should be enough, one for the ailerons (or just one aileron) and the other for the elevator. And in the case of flying wings, e.g. ME163, as elevons.

The goodlooking side of the profile to be made from 5mm foam, if it is a radial engine, the spinner maybe left off, but if it is a sleek spinner faired nosed fighter, the foam profile should include the spinner (the propellor spins infront of the spinner). The left side of the fuselage should be covered with paper printout of the fuselage profile, this way the model is not bland and I don't have to spend too much time to pretty it up.

The wings are similarly constructed of 5mm foam, covered with paper printout, right over the hingelines of the ailerons.

The wings should be around 30" for 3S1300mah, 28mm motor, and maybe 24" for dualsky RTR motor.
