Mintor 140 Bearings

[rcaerobob at cox.net]

I'm sure both David Harmon (suggestion about 50-50% mix of methanol/castor oil as after run) and Tom Collins (BuyRC.com importer/distributor) will reply.
  I'm using the SS brg in my OS 1.60, and it is very clean after 50 flights.  I'm using spray Amsoil MP1 "metal protectant" on the advice of Dave Lockhart, and that's all in the OS.
  In the Mintor, I haven't yet run it, but WILL be using the Harmon 50-50 and Mintor-suggested procedure.  And SS bearings, if they are available.
  Just my .01 worth....
