The MVVS 1.60 (Evolution 26GT) is very strong, and reliable. Installs easy, Setup is easy, and Starts easy.... The price is high, and you must get a good muffler.... The wrap around pitts that Horizon sells is a good one... and tuned silencer from MVVS is very good...

I ran mine on several models.... 74inch Staudacher 13lbs.. great IMAC plane
84inch Taylorcraft 17lbs.. again great flying model
Hanger 9 Funtana 90.... good 3der
80 inch BalsaNova.... would hold hover at about 60% of throttle... 18x6Evolution wood prop, and tuned
pipe.
