The Prototype flys almost identical from the flight reports I have read on the Sukhoi. Landings are as you mentioned extremely easy with the slightest touch of throttle, the big cowl slows her down nicely.
I have the Yak almost finished with a canister, I previously had a pitts wraparound but wanted to try the tunnel out. Now if the weather will cooperate I will get a chance to fly it... Should be fun with the additional power (I have a MVVS 45 mounted on the nose, which flew it very well previously)..
