Hi Scott,

Yes I've seen that problem before; shame there's no way to fix the casting.

I've bench run the 185 for nearly a complete tank and had no sign of the issue repeating. Power is good (7100 rpm on 21 x 10.5 APC) and idle very consistent. However I have yet to re-run it in the air and after sustaining damage to my Axiome + wing, will be unlikely to run it for quite some time. I'll let you know if & when I do

Best wishes

Keith
