I dont know of anyone that has used the 13x4W on this model on a two stroke...

Personally, I think I might go with something else.... its not an ideal prop on the four strokes but then you are looking at lower rpm.

Try it and let us know, but dont forget, C50 is not a Fun Fly so dont expect it to fly like Hype on this blade..

3010s have been FLYING out the door !

I got all the ones with broken boxes ! Just enough to kit out my C50 in replacement of the orrible 591s.

I have the APC 14x5N on now too so as soon as I have tried it I shall let y'all know...
