It is a big heavy model with a large presence in the air. Fly`s like its on rails, tracks straight. Recommended C of G is good, only requiring a dab of down inverted. Roll rate is slow and at the recommended throws do not use exponential, but use 40 to 50% expo on elevator. There was a carbon rod missing, and Hobby88 kindly offered $10 off the next kit I purchase in Lieu.
