Hey Russ
You and me have alot in common
I was in the electronics trade for about 20 years too !! ( ran my own lil business )
Also hated all that "digital ready" sh1t applied to components !!
Oh, and you are in the UK too.

Re prop balance - yep more important on these motors and some of the I.C. ones are really bad ( Taipan in particular )

I just got busy at work so better get doing what the boss needs me to do !!!

Talk later
