Acro RC airplane

First try to made a rc airplane with a 3d printer.
Result is 440 g. with battery
You can see performance test of motor with various prop
Motor is a multistar V-spec 1808
20A Esc (that is limit if you use a 3 blade prop)
and a 1000 battery
I use balsa wood 4mm for reinforcements near motor and for servo supports
I use a polyester rod for move the rudders (reinforced by cyanoacrylate glue)
Note: this motor has a high torque, so i need use a mix in transmitter radio for give anti-clockwise set on wing ailerions, connected to engine power
