Noob Question - when to change blades

[Woodstock]

Hi guys,

Newbie question here, but when should i think about changing my main blades? I have a mcpx that has been having a couple of run ins with stationary indoor objects (desk, table, sofa, radiator.... You get the picture ) how much damage is aceptable on the main blades? I have a few dinks on the edges but the heli appears to fly ok. Do i just wait until an issue becomes apparent?

in general any damage is a no go but mcpx just use your commonsense dents will be fine, if you get a crack on tailing edge abit of glue is good but only till next blade strike but any splits on leading edge replace or big cracks or if it becomes unballanced.

i know its little but can do some damage so try keep it away from eye level especialy if blades have slight damage

all the best terry
