RE: OS Vspec question.....here we go again
If you look at any nitro engine the backplate will always have some marks. The backplate holds the conrod onto the crankpin.
Anyways Ive taken the pic last night with my phone if the qaulity is not good enough I'll take another with a decent camera.
It is difficult to see the wear feeling it is very loose. I havent had that much play on any Nitro engine ever.
