Good morning, i would like to drill a bore on the top of these struts https://hobbyking.com/en_us/alloy-oleo-legs-205mm-straight-1-40-50cc-class-2pc.html
to fit the pin of these retracts https://hobbyking.com/en_us/servoless-retract-with-metal-trunion-for-large-models-51mm-x-43mm-mount-2pcs.html .
Does anybody know which is the maximum depth (more or less) that is possible to drill without damaging the internal system? Thank you
