Hey everyone, great site with a ton of useful information. Any idea where I can get a video or description of how to remove and replace the Tail gear/pulley assembly? Can't seem to find this info anywhere, and it looks like a bear to replace.

Thanks!

If you look at the "bladehelis" channel on YouTube, you can find the maintenance videos contained on the cd that came in the box with the 450 itself....plus all of their other videos.

I just used this guide, and now I have a spare motor waiting to go in, with some lovely
Boca Bearings in there

The stock bearings were a little tough to get out but came eventually

So when trying to place the C ring back on, I lost it in the carpet. I don't suppose I can find this C ring anywhere to purchase? A whole new motor for a part worth pennies stinks.

Stock motor - I bought some Traxxis e-clips that worked fine. I don't know the p/n off the top of my head, but I can look tonight.

I have quite a few, so if you can't find them locally, I'd be happy to send you some. No charge.

Thanks for the offer!

I did find the c ring with a magnet thankfully.

Scratch that...while placing the clip on the needle nose and about to insert in the plastic bag, it popped off...no idea where it fell, unlike last time.

Finally. Found it again, and after 2 quality engineers assisting, it is finally back on. What seemed to work best was tweezers. Got it in the groove easily and then used the tweezer tip to push it on. Worked on the first try. Needle nose pliers were not working.

I measured the c ring for future reference.

Inner Dimension diameter is 2.5 mm (.098")
thickness is .38 mm (.0149")

This one should work. ID is .102 (.098 is within its tolerance range) and the thickness matches at .015.

Hey, Blade..Can you make the circlip on the 220 motor smaller, Please.
Oh, and can you please magnetize it too?

[Diogenes]

What's the bearing size on the 440 motor? Is it a 3x7x3 like the 420?

Got a motor that I broke dwn today that you can move the inner race on the bottom bearing side to side with the shaft out

Shaft has marks but not grooves, which I think will be ok

I think Coco66 miked it out for us on the 450x forums. You should be able to find it under advanced search if you look for his posts.
