So I'm about to mount the two front cyclic servos when I notice there are parts missing in my kit! Well, turns out I'm using an old manual and the "servo washers" are no longer included.
Seeing I have no washers nor servo mounts available, I was forced to stop the build for one day. Yesterday though, I was fortunate enough to get to borrow some alu mounts from a fellow Agile owner

While talking about our helis he could inform me that him and I are most likely the only Agile 7.2 owners in Norway

How bout that?
Anyways, I was able to mount the servos.
The servos were quite the loose fit, so I opted to shove them upwards to align them with the frame before tightening into place. I think I'll be revisiting these before maiden, as I'm not quite comfortable with the current solution (afraid the forces might push the servos around (even though I tightened them gooood)).
I also have some concerns about the height alignment in relation to the elevator servo which is mounted to the frame, opposed to the other cyclics which are mounted a top the drivetrain. This might cause a misalignment which again will give me problems at the swash. I'll deal with all this when I get to the head setup.
Took the drive belt out of its bag, wiped off most of the silicone grease and set it into place.
Before tightening the drivetrain into place, I loosened the lower bearing plate and also installed the main shaft. This to make sure there are no misalignment between the two plates.
Drivetrain mounted and awaiting motor.
Compared to the Goblin solution for tightening the drive belt, I like this one much better! There are no springs and nuts holding the motor in place - just four simple bolts. I will only set the bolts in place for now, as I will be removing the motor again later.
Bad picture, but can you see the sliding counter bearing under the pinion? Pretty clever
Motor in place, awaiting belt and ESC connection - which I'm going to to later on in the build.
Looking good so far.
