where to buy bearings in calgary?

[RDNanoGuy]

The bearings you need should be available at any hobby shop that deals in RC cars. Try pm hobbycraft up by big als or modelland on 17 ave sw.

The bearings you need are

7mm x 19mm x 6mm

And

8mm x 19mm x 6mm

You need one of each per mp40. Get the rubber shielded ones. They are quieter than the metal shield type.

Good luck.
