there not durable, but that is good I do recommend them they save a lot of costly parts. Like servos, feather shafts and more
If your a beginner I would "NOT" upgrade to the aluminum parts. Just stay with the stock parts they are cheap. And I think some of them are made to break to save the more costly parts. I have a lot of crashes under my belt and I went all aluminum up grade. I would have saved a lot of $$$$$$$ if I would have bought stock parts until I got to be a good pilot. When I crashed my 230 s ,It was a bad crash. Because the main grips broke nothing else did. I know that save me $$$$. And servos. Plus these cheaper small heli's are not worth up grading wait until you get a big boy heli. Or a up scale small Heli
