I had a spool issue on my 180rx. Spitting and sputtering with varying rpm and temperature and eventual shutdown. Luckily it was prior to takeoff. It was similar to issues I've seen with high humidity and temperature. The day it started though it was 60 degrees F and 10% relative humidity. I set the spool to very slow and seems to have resolved the issue for now. Looking forward to the update and getting my throttle response back. Model is grounded until then. Now that I know there is an issue I probably wouldn't have messed around with ithe settings and just put the model up. I am not condoning or saying this is the way to stop gap this issue, I am just saying what I did based on symptoms the turbine displayed at the time.
