I have stock props and generic props on my mini.and I have untighnd them numerous times and put them back on due to me trying to fix motor caps from vibrating.i tryed sticky adhesive but it didn’t work so I left them like it was.. just wondering about how the different props could effect the mini.i did even them out tho one of each on each arm.also how me untightning and tighten the screws could effect the mini.the yellow props are of course the generic
