We have had every size Stinger at our field. I had a .40 an have a based giant (Super Sportster like 89" wing.)

All fly well. The bigger the better. The 60 should be nice. They do like being overpowered, stick with the high end of the recommended engine size.

With low throws, they handle as easy as a trainer. They can be quite responsive. Not a 3D or aerobat, just a great combo of low speed, high speed and responsiveness. These are everybody's "just fly for fun with no hassles" planes. Most have warbirds, Extras, bipes etc that we fly for a challenge, but keep the stingers for every day use.

BTW, beef up the wing saddle at F2, trust me on this.
