Jim, acording to my bathroom scale the Stinson weighs 21# minus the cowl and wheelpants, as flown today with the the homelite 33cc and 18x10 prop. This combo has plenty of onions for this plane. after all with 100.5" w.s. and nearly 1500 sq. in. of area the Stinson is just a glorified Piper Cub,ha,ha. speaking of multiple wings my curtis hawk is sitting upstairs just begging for a new homelite 45cc conversion.... That bipe flew like a big trainer with no bad habits and was very aerobatic, I even made several helicoptor-like landings in a stiff breeze... I think twin 33`s in your ME 110 at 30# should scoot along just fine. BTW how do you adjust the needles on you tripe? I used a pair of hemo-stats and turned em a little at a time, not the best way I`m sure but I did get em close. Ron
