Hi Guys,

I am using the 8425's in a jet at the moment in Australia and yes they are the same servo as the 8411.

I do not know why they have different numbers but it seems to be a local (ANZ - Australia and New Zealand) thing.
This is the same story for the 9401 mid size servo which is the same as a 9411 everywhere else!

Perhaps it is the local importers way of identifying servos and confusing people.
They have succeeded on both counts!

regds,

Dale
