I flew a lite squared tri-gear model 4 with 912 uls and it came out to 725lbs. Flew great. Lots of avionics and nice interior. Also flew SkyStars factory Lite Squared. It flew OK but was kind of draggy the way it was configured even with the 100 hp Rotax up front.
Remember that is the same wing and engine that lots of guys are flying 800 plus pound model 5,6. & 7’s and having tons of fun. You may find ways to lighten it after purchase. Just weigh it after and calculate the weight and balance. Oh, and congrats on your purchase.😀
