Default Stihl FS 80AV Conversion

Gday to everyone here......
I am currently building a 1/3rd replica of the Graham Lee 7/8th replica nieuport 11 ultralight (Phew, confusing or what)
Reason I have decided to do this is because I was going to build the real replica however I am limited to space until I move

I am going by the plans on the Graham Lee, which is tube and raq wing construction
I really didnt intend to put a motor and RC equipment on it and get it off the ground, however why not ....

I am looking at using a Stihl FS80 AV Weed eater motor, however I havent had any experience converting this motor to be used in a plane
Details of the motor are below..... Any and all advice is more than welcome

The information below is for the FS80.. Dunno what the AV stands for and if it makes a difference to the engine information


Single Cylinder 2 stroke Engine
Displacement 1.55 Cu in (25.4 cm3)
Bore 1.34 in (34mm)
Stroke 1.10 in (28mm)
Power according to ISO 8893 1.3bhp (0.95kw)
Idle Speed 2800 rpm
Engien cut off Speed 10,500 rpm
Ignition - Electronic Ignition Magneto
Fuel - All position Diaphragm carby with integral Fuel Pump
Max Speed of output shaft (Cutting Tool mounting) 7,500 rpm
