The ST90 will fly it okay but that's about all it will do, just don't expect the model to have much aerobatic performance with that engine up front. I had a ST90 in a 68" span CG Extra and at 8.75 lbs it's flight performance was just so so.

The site is wrong, it's actually a 72 or 73" wingspan. They never changed some of the specs since they stopped selling the old (ripped off) 120 Yak.
A 1.20 2-stroke was right for that plane (69"). My guess is you will not be happy with a .90, regardless of what plane you got (69 or 72).
Ideally, a 1.50 4-stroke would be good.
