We just finished assembling our Brillelli 40cc powered Yak last night and if the weather cooperates we will fly it this afternoon. 12 lbs 2 oz. Hitec 5645s on ailerons and elevators, 5985 on rudder and standard HS-425 servo on throttle. Fromeco 2400s on ignition and flight pack. We ran the motor last night and were very impressed with the power. We are running a Mejzlick 20x7. I'll post our results as soon as we get to fly it. Look for a review by Scott Stoops of this combination in an upcoming issue of Fly RC.
