The 0.91 2 stroke is larger than Sig recommends for this model. Any issues there?
Not if you know how pull the left stick down.
I was recently in the market for a motor like this and was looking for a .91mag in the $150 dollar range and best I could find was closer to $200--I bit the bullet and paid an extra $65.00 and bought the SA100 banking that I will not plant it in the ground and will be flying it for a long time.---BTW I would have bought the ST.91 a year ago and still think it is a lot of bag for the buck.
