Rudder set screw sizing?

[teddyboy]

Ran my UL-1 this weekend and it ran great, with the exception that all of the setscrews in the rudder vibrated out. Does anyone know the metric size of these screws where as I can order some.

Thanks for any help!!

The 2 that are on the rudder that hold the shaft are 3m x 4mm long - do you need the one that holds the servo arm as well?

Thank you, I just ordered a bag of 20 from Microfastners for about $1.80.

Plenty of spares. I will have to use locktite on them in the future.
