sig sukhoi
We have a few of the Sig Arfs at our field, and they look very nice. One flier has the FPE 2.4, one has a U.S. 41 cc, and the one I like has a G-62.
Both of the smaller gas engines don't seem to have enough umph, but do fly the plane ok. The G-62 is probably a bit too much, but boy does it power through the maneuvers.
