favour (McMaster Carr)
Indeed I won't be surprised if the new rods to fit snugly into the pounded
out holes... that would be "too easy" lol (but not ideal as they will
pound out again sooner de to uneven seating/support)
In case they are too tight, I have also sourced a 0.098" reamer locally
(equates to a #40 drill size).
Finger's x'd that this works, as the hinges on the aileron and anit-servo
tabs are glassed in on one side :-(
Cheers,
PeteZ
