The Airline is Boeing 737 full composite . but it is a oem models become start to selling , but don't talk too much here , it is customer new models , Airbus models is for another dealer will appear in market very soon , But also talk in PM . and the 737 photo will disappear soon , not good open here ! Sorry , The size still in 50/50 is which size 1/9 or 1/10 ?? in fact 1640 mm is not so big . the wing is very big . it wll load some power for flying . so i think don't do too big size . Can keep the length in 1640mm now . i don't want it size close to 120mm system . 120 mm totally cost raise a lot , especial the esc ! 120 A at least . and the fan motor also bigger a lot . and battery set also bigger , Keep it 90-100mm fan 8s battery . i think is ok !
