Jetcat balancing
 

I have just bought a second hand Jetcat 160 which has 5 hours on the ecu.

I was surprised to see the standard of the grinding on the front wheel, which I have read online is nothing to worry about and is a second balance done when the engine is assembled?

Do Jetcat sell these as new with grinding like this on the front?

this is normal dont worry
jetcat balans the turbine wheel and shaft
and then they assamble the engine
and then they balans the compressor like this

I see similar on mine. I am guessing they grind that particular location for a reason and looks hard to reach hence the freestyle grinding pattern.

Normal for all brands, and you're glad it's there!
