Mine is a great flyer as well, I have a G26 on it. Mine wants to pull to the left on take off when I bring the throttle up slow, so I initially bring it up slow for about the first 10 feet then go about 3/4 or more throttle and the tail lifts up nice and it tracks straight with just a little rudder input. I do have quite a bit of nose down trim though that I haven't been able to fugure out why. I'm wondering if the top wing needs a degree or so of nose down incidence.
