I hesitate to post this as this thread is about the Extreme Extra 300, but this might clarify some of the misconceptions about full-scale competition...The full-scale competition world really has no relation to how well a model flies - as most models have been significantly altered from scale to improve their flight performance.
From a full-scale perspective, the Sukhoi and Cap 232 have dominated World competition for the last 15-20 years. No other airplane even comes close in number of competition wins. The Edge, recently, has shown very well in the hands of Kirby Chambliss. The Extras were slightly successful early on, but haven't been for many years. The Yak 55 is an older design (1980's), is all metal and heavy, but is still very successful at the Advanced level (Unlimited is the highest). The Yak 54 has not been successful at any level of International competition. In fact, to the best of my knowledge there were only 12 built, and several of those have been destroyed in accidents. That isn't to say that the airplane isn't a good airplane, is just isn't the mount of choice for top level pilots.
I have flown and competed in both the Sukhoi and the Yak 55M (not SP) and they are both really nice airplanes. Very similar in feel. The Sukhoi is lighter and ours has more HP than the Yak 55M, so it does have more performance. It is also a cleaner design using a composite wing rather than aluminum with big rivets, so that only adds to its performance. I would guess that the 100% price difference between the Sukhoi and Yak equates to a 15-20% difference in performance.
As far as the Yakk 55 "SP" that is an entirely different animal. It is a highly modified Yak, done not by the Yak factory, but by a third party to attempt to make it competitive at the world level in Unlimited. To the best of my knowledge, it hasn't been successful.
