noticed the other day my on arm on the inspire was lose, so I shimmed it up like on the youtube video I saw using a piece of bicycle tire tube and shes rock solid now but in the process of taking it apart I noticed a we small crack its not very big but has me a bit worried if its okay to fly like this, ive included a photo of the crack what do you all think the rest of it looks good except for this or is there a way I can fill the crack with some sort of glue, I dont think its gonna crack any more but has me worried, what do you think?
