Default Can a $10 "pattern style" airframe really exist?

Hi all,

Well, I've been playing with my pink foam again... http://home.comcast.net/~crazyherb-rc/
This is my initial design, and I'm sure it may have some distinct inadequacies to a $2000 carbon/fiberglass airframe.
I'm gearing this toward the average sport/3D flyer that may want to try their hand at a more "pattern looking" airframe for dirt cheap.
(Namely MYSELF)
It's actually a semi-profile (1.5 in wide fuse)...

This model, if successful will be scaled up to 2 meter class (3 in wide fuse) (I have an interesting twist I'd like to apply to the bigger one, but that's kind of secret for now).

Here's a few of the stats

Span - 48
Length - 48
Area - 705 (wing) 955 sqin (total)
Weight (dry tank) - 4.5 lbs RTF
Engine - .46
Prop - APC 11x5

With that being said....I have a couple minor questions, and I'd love to hear comments from ya'll.
(check the web link above for many more construction photos)

1. What are your first impressions? (Yes...I know it's PINK!)
2. Wing location? Horz Stab Location look ok?
3. I have a pretty square rudder....will this effect coupling ya think? How do you foresee the flight characteristics with this design?

The FAT fin and thick horz stab should help slow the downlines quite a bit....I've proven this with a couple of my other designs.

So...what do ya think? Like? Hate? Cool thing about this is there's about 4 hrs construction time...and about 3 into designing/drawing.
Can't really argue with that....hehe...

Looking forward to the creative comments!
