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,

Glad you managed to source what you needed from the US. Can I ask how you are planning to ream out the hinges to take this new, larger pin, or are the hinges sufficiently worn that a 2.5mm pin will just slide in anyway?
Thanks

My hinges are worn and require replacement or reaming/fitting larger pins (a common issue for all us flyers). Std 3/32" 3087 welding rod would be a terrific idea for all new builders - to replace the factory-loose pins in std aviation extruded hinge material, and prevent/reduce this wear issue. Sadly, once worn, 3/32" will no longer fix a worn hinge problem.
Thus I am looking for a unicorn size 2.5mm (0.098") stainless (308/316 etc) close tolerance rod.
The only place I've found it is of course Mcmaster Carr - who will not take my order. Is there a kind USA-based Europa-ite willing to order for me and re-post to me up here in Ottawa, ON, Canada K2S1L1?
the item in question which may also be helpful for other builders/flyers:
https://www.mcmaster.com/rods/diameter~2-5mm/
"Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are precision ground to meet tight diameter and straightness tolerances.
Stainless steel shafts are more corrosion resistant than steel shafts but also more difficult to machine. 316 stainless steel shafts have excellent corrosion resistance.
Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.
