I have a SIG Extra 300XS with a OS 1.60 in it. Its great for Pattern flying, but the elevators are too small to do 3D. Some people I've heard have been able to get the plane to hover,but I think thats it.
You Moki is more then enough power for the Extra 300XS
Sorry no Pictures. All Sig Extra 300XS look alike, except mine.
