I bought one too.
I was going to ask what the short standoffs are for, but looking at the pics , they are for the dle30/35 the long ones are used for the eme 35 (which I'm using)
I found a fault in the brushed motor on mine, the brush mounts hadn't been crimped to the black housing on one side, so they were flopping around,an easy fix, but a few may not have noticed it.
Getting it all lined up and running true was a bit of work but it appears to be ok.
I haven't done the final fitting of the prop bolt yet, what would be the best thread locker for that?
