Miniature Aircraft Nitro/Gas Helicopters > Bearing part numbers tight shaft?

I have been looking for the bearing part numbers for the extreme. I can't find them anywhere. Anybody have a bearing cross reference chart? I have about 6 shafts I purchased for spares. I do not remember them being this tight. I mean they are so tight that I have to tap them in and have a hard time removing them without a puller. Have I missed something?

Go to the Bocca bearings site. They have a kit that has them all listed.

What I am really looking for is the main shaft bearing sizes. I want to replace them with Boca bearings. I have a ton of other bearings

I'm wondering this too...for a stratus though. The bearings are not listed anywhere in the manual

Along with other common parts, like tail gears (the old plastic ones anyways) and the tail shaft, etc...)

I believe they're 10x19x5 can anyone confirm?

Thanks for the post NewHeli, I know the bearings are the same for the stratus. I have 3 but I want to go to the Boca bearings. In the kit it lists 10 mm bearings but a total of 5, 4 one size and 1 other that are all 10 mm. I may just order them directly.

For future refereance, if you email bocca bearings and tell them what you are looking for they can tell you the size of the bearing in question. Especially since they have taken the time to make a "kit" for all the bearings included in the heli.

The link I attached in my first post is the kit fot the Fury Extreme and it is the same bearings for the stratus.

I contacted MinAir and they said that they should be tight but maybe I have some oversized shafts. Dr Ben could you jump in on this. I know tight is good but this is really strange.
