Futaba servo arms for 500?

[mr2rbo]

Where can I find the Mikado servo arms for my BLS451 in stock? Can I use any other servo arm for this application? What about the DuBro arms? Thanks

I'm using the Mikado arms on my BLS451 and got them from Espritmodel.com but it looks like they are out of stock right now. Here is a link to Aero-Model that may have them in stock (didn't want to create an account to find out).

I'll bet you can use the stock arms that came in the servo package. One thing I found with the Mikado arms is that I had to add subtrim to two of them to line up at 90 degrees.

If the stock arms have holes at 20mm (flybar) or 16mm (flybarless) then you can use them.

Here are some from GrandRC but I'm not sure of the distances.

or Readyheli and cut them down to size

I'm sure there are other places...
