K4 yo
*snort*  Noob plane.  Everyone flies them.  Getting as bad as the Spitteen. 

 The look I am visualizing on RB's face as he read that.  Priceless.  

Kidding.  Love the K4. Handles great...fast...climbs like a bat out of hell.  My issue is the big tater tossin' gun.  I'm am a average shot (at best)...but i just can't hit anything consistantly. That's the main reason I fly the G14 more often. 
Strangely, I can hit fairly often with the same gun in the Ta152....but I think that has more to do with the extra 30 rounds of ammo. I also find it easier to get shot angles that compliment the 30mm in the 152 than I do in the K4.
