hey no problem man
i just wait on my fiberglass spec cowl to come in

,i think she will look alot better ,if the 13/4 flys the way you like then fly it ,i have a 14/4 on my magnum .51 xls,and had no problems ,i have about 20 flights on it ,and about a 100 take offs and landings [they are my favorite]

,i love the way she flys with the big prop ,it acts like a climb prop on full scale pa-18 ,will post pic when my new cowl comes in
im trying to make scale gear ,but having trouble ,i think ima have to shell out 120<br type="_moz" />
