The 100 turns a 15 x 6 faster than their bench mark.
Horizon's specs for the 115 are somewhat surprising, I just ran 14 oz of fuel through my new to me 115
This engine is clean running throughout the entire rpm band. It has so much compression, I chickened out on using the chicken stick and went straight to the starter. The Sullivan Hi Tork turns it very well. The chicken stick would have notched the backside of the Xoar.
