I had a Hobbico Twinstar (deceased) that weight about 8 lbs with full fuel (I belive that tha manual specified a weight of approx. 5.5 lbs.) I flew this airplane often in gusty winds, and I could hardly tell the wind was even there. Even though I gad to take off and land fairly fast, the landings were rock solid. So, I think a smaller, heaver airplane flies better in wind.
