thanks for the update Pat, looks like winner. I am still in awe of the fact that a 73" wingspan 1/4 scaleish airplane can be flown with a 1.20 sized 4 stroke! I have had several 1/4 scale airplanes and all of them have had the 1.60fx and peformance was good but never great. This is a great accomplishment if it turns out to fly well on the YS 1.10
