The best question to ask first is what class or rules are you flying? Once you have that answered, you can pick an airframe. I see you are in Onterio. I'm not sure what is most popular up there, it might be a mix of Scale and B class open. Open B class uses .25 size engines. Current state of the art in B class is longer wings, 64-72" long. A Floyd is seriously out classed, for example.
However, if you are flying with a bunch of guys who mostly fly SPADs, Gremlins or other planes in the 48" span range, then you'll probibly be best staying in that range as well.
Some other planes worth looking at for .25 power (B class) (in the order I think of them):
The Predator series, Predator( 48" span), Panther (50something) and Predator X (72") from
www.TufFlight.com are very durable, great flying planes.
The Avenger from
www.TeamSeaholm.com is one of the best planes out there. This is AJ Seaholm's design he is now kitting.
GRS models sells the Falcon, a 72" flying wing that is amazing in the air, though suffers a bit in the durability department.
Lee Liddle and (I think Roy Appleton, going from memory, might have something wrong there) are kitting Lee's Cobra. The Cobra is one of the best handling planes out there.
www.hattrickrc.com, run by Dr. Evil, has the flat bat, a very durable, and very solid performer.
I don't know if Ben Morrow is still kitting Pirana's at
www.downhomerc.com or not. If so, the Prianna is a very good plane as well.
One thing about combat, the pilot matters a heck of a lot more than the plane. The Avenger and the Cobra have probibly won more contests this year in B class, but mostly because they are flown by guys like Eric Wegner, AJ, Lee, and others.
The list above is far from complete, and there are a lot of other options that are darn good planes.
