We put one in our 310, I flew with it a little and it was ok at best, however I was just out goofing around nd and I think it was operator error.
My partner took it to Florida and it made a big difference, now t the freezer he was hoping for, but it kept his wife happy and the kids that normally get sick didn’t. In talking to him, it didn’t sound like it was fully putting out. Not sure if we have a problem or operator error.
We are down for a month for annual and avionics, going to Florida in August and can give a better pirep then.
