The engine is not here jet but I will post how it performes.

Yes it is the new 82 AAC GK. Reason I choose it over the others is performance and weight and 251$ for the GK is unbeatable.

size HP weight (g)
.72 1.2 470
.80 1.3 540
.91 1.6 520
100 1.8 550

.82 1.5 462 (new)

For me it's the best power to weight ratio I've seen at fourstrokes.
