OS91 FX equivalent?
 

Hi all

I am thinking of buying and converting a speed plane (called "Cobra" from Fliegerland shop, Germany), which is normally powered by an OS91 FX or some even fly her with an OS 91 VF ducted fan with a 10x10 prop.
Of course the plane is very very fast (150mph+ easily)

Wingspan about 1.20m
Weight 2.5kg-3.0kg (I am not sure with or without motor, probably with OS motor)

What would be a good electric motor to get similar speed. Which prop? What ESC?
I would like to use my LiPos (Turnigy 6S 5000mA)

Any suggestions are appreciated.
