Well I got mine in the air today it flys very true, rolls are axial and fast on high rates I have 3 rates set up from mild to wild. I am not over powered with the 23cc gas but it was slightly rich and maybe not the best prop for the plane further testing will have to be done before I consider an engine change. One thing that really impressed me was it locked into a harrier with no wing rocking solid upright and slow got it into a knife edge spin and could change the rotation rate with the throttle it does pull to the canopy a little but not bad more when doing high alfa knife edge. I am looking forward to fine tuning this plane to bad winter is approching fast I am going to like this plane
