19Lbs..HOLY COW!!! Now you are making me wonder if my 160twin will even move this plane. It pulled my 13lbs 150 around with ease, and my other twin pulled my Hanger 9 182 ok with good climb rate....but it was only at 17lbs. I might have to go to a 182 twin...I'll start looking for one now,,,,even if I dont use it, I still have a 1/4 scale Cub I can use either on..
