I never thought much of most airplane foams, though depron is pretty tough, but this stuff far surpasses it. This foam is more like those stiff swim float board , or boogie board material, almost indestructible.
The speed and response of this little thing is wild fast and precise, because it is very light!
My ZMR 250 clone with no camera gear or landing gear dry is 360 grams.
This CK-250 w/landing gear, fpv camera and vtx comes in at 314 grams!
The ESCs' that come with it are HobbyWing which I like alot, and the motors look and fly good. Don't really know anything about the OrignHobby 1806 motor. Wonder if it is their motor or rebrand??
The aluminum is good grade, and the camera dampers are nice and durable. i would like to get some of these dampers to replace ones on my 250. The only thing plastic are the ESC windows and the landing gear. I also have discovered that heli style landing gear on a 250 is very nice and convenient! Landing and take off is so easy with them on just about any surface.
I am counting my pennies and seriously thinking how I could pull it off and get one ordered and make it 4S with just a tad bit bigger motors and esc.
