my 2 cents...
Another vote for MIP. Compared to Bondhus they seem to last forever, though I should say the bondhus ones have ball ends.

The shims fit the flange bearings nicely, and are only 0.12mm thick which allows fine adjustments to the bearing play. After reassembly it felt much tighter, and without and grittiness; especially cool that the arms weren't wobbling back and forth anymore. I got 3 flights in heavy winds the next day to test it out. Despite the winds I could easily notice how much tighter it flew, and the major wobble during spoolup went away.

Anyways it's affirmative: the Calandra shims are a must for dealing with lose fitting flange bearings!

When I put my Tarot 450 sport together I had to remove the shims on the flange bearings in the washout arms or else I couldn't tighten the screws without the arms binding. And on the mixing arms I ended up having to put a 2x3.6x0.2 washer in between the bearings to prevent them from binding.

I always use mip allen wrench. to me, they are the best.
Yes that one only I bought a 1.5mm hex only, and a phillips set. I don't think the hex driver is quite as good as the Align but I only use it for the feathering shaft or screws in hard to reach places because of it's longer shaft and smaller handle.

Received my Emax ES9258 and installed it last night. Man, that thing is huge!! It almost looks comical in comparison to the cyclic servos. (In the photo you can see how it dwarfs the MKS DS-480 sitting on the table that it replaced.)

Did a test flight under the floodlights in the backyard last night and I'm impressed. Absolutely solid as a rock, with full pitch pumps giving maybe 2 or 3 degrees of tail kick. Can't wait for this weekend to really test it out. Tic-toc heaven, here we come!!! (I just know I'm gonna total this poor heli on Saturday. )

The ES9257 is the same size as the ES9258. I can't believe you have it on a 250. You might as well put clown shoes and a red nose on it as well.

Hmm, just noticed the 9257 is same as the 9258, but 5 grams lighter due to plastic gears. Is there any need for metal gears on a tail servo? Would probably be better off with the lighter plastic gear version since I've had to add lead to the nose to get the balance right.

i got my KFC HEAD and did a pre flight test , this thing flys itself . this isin't flying , this is more of a relaxing day at the field . i like it though , but wont buy another because of the cost . flybar free , flybarless 200 more donuts . the good news is it used analog servos for the cyclic , just need a basic digi servo for the tail.
still in one piece

Well I finally found a solution for the links rubbing in the corners. I put a 450 Pro flybar cage on it. It worked perfectly with the Sport fixed links (the Pro links are actually too long), the only adjustment that was needed was shortening the servo to swash links by one turn and lengthening the pitch control links a few turns to bring the washout and mixing arms level at 0 degrees. The helicopter also seems more stable with the wider flybar cage.

Starting at around 8 degrees cyclic at maximum collective and with the stick in a corner the top of the flybar links will rub the blade grips. But this is still a lot better than having links rub the mixing arms under the same conditions at 6 degrees cyclic. (and I won't be using 8 degrees cyclic or flying with the stick in a corner anyway)

Found another US based clone distributor, they're selling a WinRC 450 Sport kit for under $50 and a lot of WinRc Pro and Sport parts. Located in Elk Grove California.

Ordered a pack of these apparently brass boom holder bolts.
