took it up for its first flight today!!!!!! It couldnt of gone any better!! I checked all my throws and made sure everything was operating ok..then I fired it up and slowly started to taxi down the runway. I then throttled up gently and she tracked nice and straight with almost no rudder input untill she left the ground at a nice rate of climb...It didnt need a lot of trim adjustments so I was real happy about that..I flew about 5 flights today and let me tell yah, that os .46 has more than enough power for the plane...
