Ive seen the Mig 29 UB two seater at FHC, Paine Field WA, but not an SU 27. The SU is a massive "fighter"!!! I cant believe how the AD model dwarfs the CARF Euro! Wow thats a big buggie!
Nice transpo-cart!

SU 27K was the navy variant with canards and other slow speed aero aids.
SU 37 was the technology demonstrtrator for thrust vectoring, has canards and other developments - never went into production
