Disabling engine damage in config (Hughes H1A payware)

Good evening. I recently purchased the Hughes H1A payware aircraft and even with "engine stress causes damage" unchecked in the settings, it will still die and crash even when I keep my RPMs low kind of like the default P-51 racer. I suspect this is a feature of the addon itself and I've looked thru the config file and cant seem to find anything. I've also noticed the engine just self destructs whenever I pause the sim then start it again. Does anybody have any tips on how I can disable this.

Thanks.
