3w-75ius vs 3w-75 qs
I will be putting one of these engines in an aeroworks 31% 540T, which also happens to be my first large scale plane. Since I'm new to gassers, will I notice a difference between these? Is the QS worth the extra $$$? Will the QS even fit in the Edge? Or should I just stick with the normal 3w75ius?
Thanks
