It may be a bit expensive for some, but their rotor heads are one of the best qualities I have seen. I used their heads on 500, 600, 700 and 800 size helis and have never had an issue.

They ship to the USA and communicate very well over email.

Excellent, thanks for adding this one! I’ve never heard of them, but I’ll likely give them a try in the future based on your experience. I also like that they take custom CNC projects. I have a few things on the table that I might consider reaching out to them for.

Update: After being unobtainable for the last 2 years, the 500 scale plastic blades have returned! Unfortunately, this comes just after Motion stopped carrying 500 size fuselages..
